Installation of Jahia on various platforms

November 14, 2023

Jahia's official and nightly builds are distributed as installation packages, which contain the entire software suite (Jahia Core Platform, jContent web content management system, Studio) as well as the Digitall Website demo, several template sets and dozens of composite modules.

Main installation steps

  • Download the latest stable Jahia build from by choosing the right downloadable package for your operating system.
  • Double-click on the downloaded installation package, which will start the installation wizard.
  • On Unix servers with a graphical environment, you can start the installation wizard by running java -jar <your-downloaded-jahia-jar>.
  • On Unix servers where you have no graphical environment, you can start the installation in Console Mode:
    java -jar <your-downloaded-jahia-jar> -console
  • If you need to run the wizard in Console Mode on Windows, you will need to open your command prompt with administrator privileges.
  • Follow the installation wizard. See the next section for a detailed description of install settings.
  • At the end, you can let the wizard launch Jahia (if the bundled Apache Tomcat server was selected as an option). Otherwise, you can launch Jahia using the generated shortcut or within the created installation folder using a console window launch the command ./ (on Linux/MacOSX) or start.bat (on Windows).
Important: The first start of Jahia may take up to 3 minutes, depending on your hardware (initial templates publication and modules deployment). Subsequent starts will be faster.

Settings during installation

Installation path

There shouldn’t be any spaces in your folder naming. For example, C:\Jahia-\ is OK while C:\Jahia\ is not.

Installation type – Discovery install

This option allows you to discover Jahia without a specific configuration thanks to the installation of an Apache Tomcat 9 server & Sun Java DB/Apache Derby DBMS bundle. This installation also provides and deploys all interesting and available modules, applications and templates.

Default application server

The default Jahia version is distributed with an Apache Tomcat 9.0.x application server. No manual configuration of the server is required, as it will be directly setup during the Jahia installation. By default, Tomcat will use standard ports (8080, 8009 and 8005). Please ensure that you do not have any other servers/services running and using those ports. Optionally, you can change Tomcat ports during the Custom Install installation type. For more information, see Installation type – Custom install.

Default database

Jahia installs with the embedded Sun Java DB/Apache Derby database engine with the Discovery install option. If you wish to get started rapidly, you can use the provided database as is. With the Custom Install option you can choose to install Jahia to another more robust standalone database during the configuration wizard of Jahia. Please note that you cannot simply switch the database at a later stage on the same installation. You will have to export the content and import it into a new Jahia installation configured with the different database.

Installation type – Custom install

If you want to install Jahia on a custom environment (application server, database, mail server configuration, different port numbers), choose a particular operating mode (development, production, distant publication server), configure clustering or LDAP providers, you need to choose the “Custom Install” option.

Application server

The Jahia Enterprise Distribution can be installed with an Apache Tomcat 9.0.x application server. If you want to install into your own server, you need to deselect the Apache Tomcat checkbox on Step 5 of the installation wizard and click Next. On the next page, you will be able to choose whether the installation is targeted into one of these application servers:

  • Apache Tomcat 9.0.x (in case you want to deploy Jahia yourself into an existing Tomcat server other than the one bundled by default)
  • IBM WebSphere 8.5.5
  • Red Hat JBoss EAP 6.x

The installed Jahia will then include some specific configurations, which are needed to make it run smoothly in the targeted application server. See Application server specific installations for further information.


The embedded Sun Java DB / Apache Derby database engine, which is used with Discovery install option is not suited for production. During installation, you can choose between:

  • MariaDB 10.x
  • Microsoft SQL Server
  • MySQL 5.x
  • Oracle 11g
  • PostgreSQL 9.x

Note that you cannot simply switch the database at a later stage on the same installation. You will have to export the content and import it into a new Jahia installation configured with the different database.

During installation, you will be asked to provide the connection URL and the user/password for accessing the database.

Furthermore, you also will be able to set whether binary data should be stored in the database or directly on a file system (for clustered Jahia setup the file system need to be shared by all cluster nodes). By default, the binary files are stored on the file system, which in most cases results in a better performance as the file content can be directly streamed from the file system (utilizing low level OS mechanism) and a higher level of concurrency can be achieved. There is also an option present to define if the Jahia DB structure (tables, indexes, sequences) has to be created first (this option needs to be unchecked, for example when running the installation wizard for installing second, third, time and for cluster nodes).

Apache Tomcat configuration

This section is available only if you have chosen to use the bundled Tomcat application server.

Here you have the possibility to configure the different ports used by Tomcat.

Web application settings

Here you have the possibility to specify the context path for Jahia Web application. If you want to deploy it into the root context (“/”), just leave the field blank.

You also need to specify a login and password that will be required to access the Tools Area: monitoring and debugging tools embedded in Jahia.

Operating mode

Here you have to choose in which mode you want to install Jahia.

  • Development
    Enables Development mode for Jahia including access to Studio.
  • Development + Modules/JahiApps/Demos
    Enables Development mode and includes the set of all optional modules, template sets and pre-packaged demo sites.
  • Production
    Includes the core set of Jahia modules. Disables development mode for template deployment. Studio mode access is also disabled.
  • Distant publication server
    Enables Production but content editing activities are limited to the Live content only.

Just take care that even if you can switch later between the modes (you can reconfigure it in, some modules will be packaged only when you perform the installation in “Development + Modules/JahiApps/Demos” Mode. Installing in Production Mode, and then switching to Development Mode will activate the development dedicated features (like the Studio), but will not deploy the additional modules. You will have to deploy them using Module Management Panel in the Administration. Refer to Modules for more information.

Differences between Development and Production modes

Here we will list the differences in terms of available features and Jahia behavior between the Development and Productions modes. From the packaged modules point of view, there are no differences between plain Development (not the second option, which is “Development + Modules/JahiApps/Demos”) and Production mode.

  Development mode Production mode
Studio Yes Not accessible
Cache Display extra information directly in the rendered page by passing request parameter “cacheinfo=true” in the page URL n/a
Rendering Display extra view/area rendering information by passing request parameter “moduleinfo=true” in the page URL n/a
Error handling Exception stacktraces are rendered in the error page. Additional (more verbose) error reporting using ErrorFileDumper in the rendering of views. n/a
Rules Watch for changes in rule files under <jahia-web-app-dir>/WEB-INF/etc/repository/rules and automatically rebuild the rule base n/a
Job scheduling


(from Spring)

If a background job is scheduled from a Spring definition file, the job is recreated (all the job data is deleted) and rescheduled on each Jahia restart. Spring-based configured jobs are never deleted. If the change is detected in the trigger configuration the job is re-scheduled on Jahia startup.
URL rewriting rules Scanned for changes each 5 seconds. The rule base is reloaded if changes are detected. No implicit scanning for changes.
Groovy patcher Scans for new patches each 5 seconds and executes them. Scan interval is configurable at is set to 5 minutes by default. Scanning can be disabled completely.

LDAP configuration

In case you will use LDAP directory as a provider for application users or/and groups, you can choose to configure LDAP provider settings during installation. If you check this option, you will then access an additional screen, where you can setup your configuration for user and group providers.

If you do not configure them during the installation process, you will still be able to do it later from the configuration files. See LDAP for more information.

Cluster configuration

You can also configure Jahia to be run in cluster mode. If you check this option, you will then access an additional screen where you can setup your cluster configuration.

Here, you will have to specify if the node you are installing is the processing server. Remember that only one node of this type is allowed in the same cluster. See Clustering for more information.

You will also have to specify a unique server identifier (or leave the <auto> value for it to be auto-generated) and declare the IP and listening port.

System administrator settings

You need to at least provide the password for the root user, who, like a super-user, always has all of the privileges in Jahia. So, you should choose a strong password and keep it secret.

Mail server

Mail server: this field contains the SMTP host name, with advanced options.

Jahia uses the Apache Camel framework for messaging. The format of the mail endpoint should conform to the endpoint required by the Camel Mail Component (, for example.:


All parts except the host are optional. See use cases below. Mail administrator: the field contains a single e-mail address or multiple addresses (separated by a comma) of users who will receive system-level notifications (for example, about errors if this option is enabled).

Mail from: the default sender e-mail address for an e-mail message.

Here are several use cases for "Mail server" field values:

  1. SMTP server does not require authentication and uses the standard port 25:
  2. SMTP server requires authentication and uses non-standard port 11019:
  3. GMail example: SMTP server requires authentication and SSL enabled (or TLS):

  4. Enable the mail server debugging option to see the details of e-mail server communication:

Folder structure after installation with bundled Tomcat

The runtime data and main configuration files are by default located outside of the Jahia Web application. This allows for more clear separation of artifacts, better customization, production deployment and maintainability throughout the project lifecycle, including hotfixes and upgrades. We will reference further in this document the runtime data folder as digital-factory-data and the configuration folder as digital-factory-config. Here is a brief overview of the folders structure in Jahia along with the important files that will be used throughout this guide. The files and folders in the Web application (here under tomcat/webapps/ROOT) should be the same as what is on the other application servers. Note, please that some folders under digital-factory-data are created on demand (upon Jahia first startup).

Here is a brief overview of the important folders:

  • digital-factory-config/
    Contains Jahia configuration and license file under jahia sub-folder
  • digital-factory-data/
    Runtime Jahia data, including database creation scripts, modules and prepackaged sites to be deployed, JCR repository folder etc
  • digital-factory-data/bundles-deployed
    Contains all the bundles, corresponding to the deployed modules. Note: when restarting the server after flushing the contents of this folder, the modules present in the digital-factory-data/modules will be redeployed, but the other modules (uploaded via UI, RESR API, downloaded from store) will NOT be redeployed, and will require to be manually deployed again.
  • digital-factory-data/compiledRules
    Folder with the pre-compiled business rules, which are generated on module deployment and “cached” here.
  • digital-factory-data/db
    The database scripts to create the DB schema of Jahia and to connect to the corresponding database can be found here.
  • digital-factory-data/generated-resources
    Contains aggregated and minified CSS and JavaScript assets which are generated during rendering of live pages.
  • digital-factory-data/karaf
    The configuration and runtime data of the OSGi container (Apache Karaf).
  • digital-factory-data/karaf/etc
    Configuration files for the Apache Karaf OSGi container.
  • digital-factory-data/modules
    Modules and template-sets located in that directory will be deployed to the server on startup or whenever a file changes during runtime. Template-sets will be available in the drop-down list when you create a new virtual site, and modules will be seen in the left panel of the Studio or in the Edit mode.
  • digital-factory-data/patches/groovy
    Includes Groovy-based patch scripts. The folder is also “watched” for the new scripts during runtime on the processing server to allow execution of patches during runtime.
  • digital-factory-data/patches/sql
    Contains SQL scripts which are executed against database schema on Jahia startup.
  • digital-factory-data/repository
    The Jackrabbit repository home, where the workspace configuration, and version storage is located as well as search indexes.
  • digital-factory-data/repository/datastore
    The Jackrabbit datastore folder where the binary resources will be stored.
  • digital-factory-data/repository/index and digital-factory-data/repository/workspaces/*/index
  • The search indexes are stored in these directories.
  • tomcat/
    Contains pre-configured Apache Tomcat server
  • tomcat/logs/jahia-errors
    Folder where Jahia error dumper service writes error reports into.
  • tomcat/logs/jahia-threads
    Folder where Jahia thread dumper service writes thread dump files into.
  • tomcat/temp/jahia-jsps
    This directory will contain complied JSPs of the Jahia modules. It will include both compiled class and Java file for each JSP. This can prove helpful in case you have an error in a template showing in the Tomcat logs, for instance: illegal start of expression. If you want to make sure that all JSP files of the templates are recompiled after a change, you may want to delete the jahia-jsps directory and also the Standalone directory in work. Next time you access a page, Tomcat will recompile all JSP files used by the page.
  • tomcat/webapps/ROOT/engines
    This directory contains all the JSP, images and JavaScript files of Jahia engines (Content Manager, Content Picker, Live Content Picker etc.).
  • tomcat/webapps/ROOT/META-INF/context.xml
    Database connection information. This configuration is applicable only for Apache Tomcat server.
  • tomcat/webapps/ROOT/WEB-INF/classes
    Besides some configuration files, here you will find mainly resource bundle files used to translate the Jahia interface in other languages. There are normally at least 2 files for each language: and
  • tomcat/webapps/ROOT/WEB-INF/etc
    The etc directory contains most of the configuration files of Jahia. The config sub-directory contains several configuration files (log4j.xml, seo-urlrewrite.xml, etc.). The repository directory contains the configuration files for Jackrabbit repository. The spring directory may contain custom Spring bean definition files, but is empty by default. The internal Spring files are located inside jahia-impl-*.jar file.
  • start.*/stop.*
    The Jahia start and stop scripts.

Discovering Jahia - first usage

This applies only if you want to discover Jahia using the prepackaged demonstration site. It assumes that you have installed Jahia using “Discovery install” or selecting “Development + Modules/JahiApps/Demos” Mode, so that the example templates and the modules they require have been automatically deployed.

  • Open a browser and go to http://localhost:8080/start.Use the root user credentials set up during the installation process. You will discover the new Jahia landing page. Click on the “Create new Web-Projects” button and you're ready to create your first site.
  • Import the new “Digitall Prepackaged Demo Website” package. After successful import, click on the “Go to Edit Mode” button to see the Edit Mode for this Digitall Web site.
  • Switch to the Live or Contribute Mode and enjoy!

Installing a production server – additional steps

This applies when you install your production server, and assumes that you have installed Jahia in Production Mode.

Before being able to create your first website, you will have to deploy your custom set of templates and modules. But during the development process, you may have used some Jahia standard modules, automatically available on your installation. Notice that most of those modules were available because you installed your development server using the development mode. As your production server uses the production mode, only the core modules will be available. So, you also need to deploy yourself the standard modules you want to use.

  • Prepare all the JAR files for your custom templates and modules, and the one for each standard module you want to use. For the standard modules, you can either download them from the Jahia Private App Store (, or retrieve them from your development server (they are available in digital-factory-data/modules/). In case you download the modules from the Jahia Private App Store, take care to download the same version of the module as the one you have tested during your validation process.
  • In order to deploy additional modules, you could use a dedicated screen in the Jahia installer, where you are offered to provider a folder to additional modules, which have to be deployed to the Jahia instance, you are installing. Alternatively, after the installation you could use Module management screen in Jahia Administration or manually copy the required modules to digital-factory-data/modules folder.
  • The modules will be automatically deployed
  • Now you can either import your site data from an export of your integration/development platform, or create a new empty site.
  • Now let your users enter content on their site.

Different types of environment

During the life-cycle of a project you will need different types of environments:

  • Development environment - each of your developers will have their own environment. Those developer environments are normally much lighter than the one needed for production. Your developers can either use the integrated DBMS (Apache Derby) or use another DBMS (MySQL, MariaDB, Microsoft SQL Server, PostgreSQL or Oracle).
  • Integration environment - this environment will help you integrate the work of all your developers on the same platform and prepare the site(s) you are going to deploy in production.
  • Production environment - this one is the last step in the development life-cycle of your project.

Application server specific installations

Apache Tomcat 9.0.x

To deploy Jahia into an existing Apache Tomcat 9.0.x installation a number of required steps has to be completed.

Next subsections describe all those steps, which are all mandatory.


The installation procedure for an existing Apache Tomcat 9 is as follows:

  • Launch the Installer.
  • Choose the Custom Install (advanced) installation type.
  • Select only Jahia Core Platform + jContent pack, unselecting the Add Apache Tomcat one
  • On the next screen choose the Apache Tomcat 9.0.x as the target application server
  • Follow the next steps of the Installer.

Once the Installer is finished in your installation directory you should find among others the tomcat folder and, if the locations of runtime data and configuration folders were not changed during the installation, the digital-factory-config and digital-factory-data folders.


Further, it is assumed that your target Apache Tomcat server is installed in the <tomcat> folder and <install-dir> will reference the folder, where you’ve installed Jahia into using the installer.

  1. Copy the content of the <install-dir>/tomcat/lib folder into your <tomcat>/lib directory.
  2. If ROOT was configured as the Web application context name, remove or rename the default Tomcat’s ROOT Web application at <tomcat>/webapps/ROOT if it exists. For example, rename it to tomcat-root.
  3. Copy the content of the <install-dir>/tomcat/webapps folder into your <tomcat>/webapps directory.
  4. The configuration folder path (digital-factory-config) has to be added into the class path to make it available to Jahia. The easiest way is to modify the common.loader variable value in the <tomcat>/conf/ file to point to the digital-factory-config folder path. For example, if the Jahia configuration folder has a path /opt/DigitalExperienceManager-7/digital-factory-config than the value of common.loader should look like:

    If your digital-factory-config folder is inside the installation folder, you could use the path, relative to catalina.home, i.e.:

  5. Note, if you decide to move the digital-factory-data folder to other location, the jahiaVarDiskPath value in the digital-factory-config/jahia/ file should be adjusted to reflect its new path.
  6. Adjust the JVM and connector options appropriately (see the next JVM tuning options section).

JVM tuning options

The default JVM options of the Apache Tomcat must be adjusted to reflect the Jahia requirements. We recommend creating a setenv.bat (Windows) or (non-Windows OS) script in the <tomcat>/bin folder to put those options. An example of the <tomcat>/bin/setenv.bat for Windows OS could be:

rem ------------------------------------------------------------------
rem Jahia settings
rem ------------------------------------------------------------------
set CATALINA_OPTS=%CATALINA_OPTS% -server -verbose:gc -XX:+HeapDumpOnOutOfMemoryError -XX:+PrintConcurrentLocks -Xms2048m -Xmx2048m
set CATALINA_OPTS=%CATALINA_OPTS% -Dderby.system.home="%CATALINA_HOME%\..\digital-factory-data\dbdata"

In a similar way, the <tomcat>/bin/ script for a non-Windows OS can look like:

# --------------------------------------------------------------------
# Jahia settings
# --------------------------------------------------------------------
CATALINA_OPTS="$CATALINA_OPTS -server -Djava.awt.headless=true -verbose:gc -XX:+HeapDumpOnOutOfMemoryError -XX:+PrintConcurrentLocks -Xms2048m -Xmx2048m"
CATALINA_OPTS="$CATALINA_OPTS -Dderby.system.home=$CATALINA_HOME/../digital-factory-data/dbdata"

The JVM heap sizes (-Xms and -Xmx) should be adjusted according to your needs. Note that the minimal value of the -Xmx value, required by Jahia is 2048m. If you have chosen Apache Derby as the target DBMS server during the installation, the value of the -Dderby.system.home in the setenv.bat/ script should point to your digital-factory-data/dbdata folder.

HTTP/AJP connector tuning options

The following configuration for the HTTP and AJP connectors (configured in the <tomcat>/conf/server.xml file) is recommended [1], which includes maximum threads and accept count configuration, compression of the response content, and more.

<Connector port="8080"
maxThreads="300" acceptCount="100"
compressibleMimeType="text/plain,text/html,text/xml,text/css,text/javascript,application/x-javascript,application/javascript,application/json,application/xml" />
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443"
connectionTimeout="20000" keepAliveTimeout="300000" maxThreads="300" />
Note: This version of Tomcat is susceptible to the Ghostcat vulnerability, specifically to RCE (Remote Code Execution). RCE can only happen under certain conditions and Jahia should not be affected unless you open internal Tomcat ports to the outside. At a minimum, we recommend that you set up a firewall that blocks external traffic to ports 8009, 8080, and 8443.

Migration information

In case of migration from tomcat 8.x, please take care of changes in the default configuration about the Security Lifecycle Listener

IBM WebSphere 8.5.5

The installation and configuration steps for IBM WebSphere are covered on a dedicated page WebSphere V8.5.5 Installation guide.

Red Hat JBoss EAP 6.x

To deploy Jahia into an existing Red Hat JBoss EAP 6.x installation several required steps have to be completed. Note that here we assume the deployment into a JBoss EAP instance, running in a standalone mode with a default configuration profile.

Next subsections describe all those steps, which are all mandatory.


The installation procedure for an existing JBoss server is as follows: ul>

  • Launch the Installer.
  • Choose the Custom Install (advanced) installation type.
  • Select only Jahia + Jahia Core Content Platform pack, unselecting the Add Apache Tomcat one
  • On the next screen choose the Red Hat JBoss EAP 6.x as the target application server
  • Follow the next steps of the Installer. Once the Installer is finished in your installation directory you should find among others the jboss folder and, if the location of runtime data folder was not changed during the installation, the digital-factory-data folder.

Deployment preparation

Further, it is assumed that your target Red Hat JBoss server is installed in the <jboss> folder and <install-dir> will reference the folder, where you’ve installed Jahia into using the installer.

  1. Copy the content of the <install-dir>/jboss folder into your <jboss> directory.
  2. Continue with the steps, described in the next sections.

JVM tuning options

The default JVM options in the JBoss’ startup script (<jboss>/bin/standalone.conf.bat or <jboss>/bin/standalone.conf) should be adjusted to use server JVM ("-server" option), have at least 2048 MB[2] heap size (-Xmx2048m), if applicable, also adding other tuning options.

This can be done by adjusting the corresponding line in your <jboss>/bin/standalone.conf.bat file (Windows OS):

set "JAVA_OPTS=-server -Xms2G -Xmx2G"

or in the <jboss>/bin/standalone.conf file (non-Windows OS) – here we use larger values as an example:

JAVA_OPTS="-server –Xms4G –Xmx4G"

The following lines needs to be added to: On Windows OS:

set "JAVA_OPTS=%JAVA_OPTS%\standalone\tmp"
set "JAVA_OPTS=%JAVA_OPTS% -Dderby.system.home=c:\DigitalExperienceManager-7\digital-factory-data\dbdata"
set "JAVA_OPTS=%JAVA_OPTS% -verbose:gc -XX:+HeapDumpOnOutOfMemoryError -XX:+PrintConcurrentLocks"

And for non-Windows OS:

JAVA_OPTS="$JAVA_OPTS -Dderby.system.home=/opt/DigitalExperienceManager-7/digital-factory-data/dbdata"
JAVA_OPTS="$JAVA_OPTS -verbose:gc -XX:+HeapDumpOnOutOfMemoryError -XX:+PrintConcurrentLocks"

Server configuration (JBoss should be running)

The next steps have to be performed on a started JBoss server instance. Please, start your JBoss server instance from <jboss>/bin folder by using: On Windows OS:

standalone.bat -b

On non-Windows OS:

./ -b

The value after -b switch means that JBoss will be bound to all available network interfaces. You could use particular one instead, for example When omitted the JBoss will bind to the loopback address ( only. After the JBoss instance is started continue with the next steps.

Create management user

When JBoss is running, you could create a server management user (for accessing JBoss Management UI) by using <jboss>\bin\add-user.bat (Windows platform) or <jboss>/bin/ (non-Windows platform). Provide the required information to add the user. Alternatively, you could add a user in a non-interactive mode: On Windows OS:

add-user.bat -u manager -p manager_123

On non-Windows OS:

./ -u manager -p manager_123

Apply Jahia specific configuration

For configuring JDBC driver, DB datasource and also deactivating default JBoss ROOT application (in case Jahia will use ROOT Web application context), the following script has to be executed against running JBoss server instance from <jboss>/bin folder: Windows OS:

jboss-cli.bat --file=jahia-config.cli

Non-Windows OS:

./ --file=jahia-config.cli

Deploy and start Jahia

The configuration is ready now and we can deploy and start the Jahia. To trigger the deployment, you need to delete the marker file:


This will trigger the deployment and startup of the Jahia Web application.


Module deployment

Modules are extensions to Jahia, which are packaged as JAR files and can be deployed on a server. A module can contain different kinds of resources: JSPs, definitions in CND files, CSS and images, resource bundles, XML or ZIP import files, rules definitions, libraries, Spring files etc. Modules are deployed by using the built-in module management screen in Server Settings, using REST API (with supplied command line scripts) or by dropping them into the digital-factory-data/modules folder. When deploying several new versions of modules, it is advised to use the REST API (see Installing multiple modules) as it comes with an optimization regarding dependency resolutions: a single bundle refresh is performed internally at the end.

Module management UI

The module management UI contains an explicit checkbox for starting or not a module, uploaded via that UI, as well as a similar checkbox for the modules, downloaded from private app store.

For more information about the module management UI, see Managing modules.

REST API and command line scripts

Jahia provides a REST API for module management, as well as corresponding command line scripts in the Jahia installation folder (in a default installation they are located in the <jahia-install-dir>/tools folder). Examples of usage of such scripts are listed below.

Note that all the scripts are available for Windows (.bat), Linux and MacOS (.sh) operating systems.
To perform these operations with a different user from root (which is the user by default), you can change the value of DX_USERNAME in the file with the selected username who must have the administration permission "Admin templates".

Installing a module

./ article-2.0.2.jar true

Installs the specified file as a module and starts it after the installation. if last parameter (true) is omitted, the module is just installed, but not started automatically.


Installing multiple modules

./ article-2.0.2.jar faq-2.0.2.jar --start

Installs the specified files as modules and starts them after the installation. if last parameter (--start) is omitted, the modules are just installed, but not started automatically.

Starting a module

./ org.jahia.modules/article/2.0.2

Starts the article module version 2.0.2. The org.jahia.modules/article/2.0.2 is a full module key in this case, which is composed like <groupId>/<artifactId>/<version> string. The start/stop/ uninstall commands can operate on a full module key as well as on a short one, like article/2.0.2 or event article, if the corresponding bundle can be resolved by that key unambiguously, for example if there is only one bundle with symbolic name article installed on your Jahia instance. The shorter form will be:

./ article

Stopping a module

./ org.jahia.modules/article/2.0.2

Or in a shorter form:

./ article

This command stops the target article module.

Uninstalling a module

./ org.jahia.modules/article/2.0.2

And the shorter form:

./ article

Uninstalls the target article module from your Jahia instance.

Notes about deployment into /modules folder

The deployment of modules can also be done by dropping them into the digital-factory-data/modules folder. This folder is “watched” for changes (new modules are dropped, existing modified or deleted) and actions are performed by Jahia to react on those changes. The folder supports module operations in “hot” (online, while Jahia is running) as well as in “cold” (offline, when Jahia is shut down) mode. If a new module is dropped into that folder, it is by default automatically started if Jahia is running in development operating mode (“operatingMode” flag value in file) or just installed without auto-starting it in case of other operating modes (say, “production”). If needed, the behavior can be explicitly controlled by adding the following flag into (or your own file:

Supported values are true or false.

Notes about module dependencies

We rely on OSGI capability mechanism to define the dependencies between modules.
An OSGI bundle, so a Jahia module, can be started if all its dependencies (OSGI bundles that provides the required capabilities) are resolved.

The import and definition registering is done at resolve state.

At startup, a Jahia module if necessary:

  • Stops any previous version of the module
  • Registers the bundle into TemplatePackageRegistry (where it computes the dependencies using TemplatePackageRegistry.computeDependencies)
  • Fires deploy event to Jahia (mostly to flush caches)
  • Registers script resolvers
  • Registers the Drools rules
  • Registers HTTP resources
  • Starts spring context

We provide several mechanisms to make the module start whatever the order the modules are deployed.

  1. We compute all the dependencies each time a module, or one of its dependencies, is started
  2. If a dependency is not fulfilled, or not available at startup, the module startup is postponed. At the end of the process, all the modules should be started correctly.
  3. The jahia-depends defines the required modules to be resolved. It also defines, in case of multiple modules deployed at once, the order to start them. Copying several modules at once in the /modules directory work as each module deployed one by one, so we cannot compute the order of deployment, this can lead to inconsistencies while the modules are starting, but should be solved automatically at the end.

Cluster deployment

Jahia includes a built-in clustered module management support. All module operations, performed via Module management UI (in Server Settings) or via new REST API / command-line scripts on any node and also including module deployments/undeployments via the /modules folder, are automatically replayed on other nodes in the cluster, so the state of bundles should be consistent across all nodes in the cluster. When a cluster node is joining the cluster it “pulls” the bundle state from the cluster and “applies” it locally. So, the module operations, listed in Module deployment, are cluster-wide (for example, a module deployed on any node of the cluster will be automatically deployed on the other nodes). Be aware, please, that direct bundle operations, performed via Java code (on BundleContext or Bundle instances), any custom scripts, OSGi Web Console or SSH Console (except clustered commands under cluster:* group), are only effective locally (until the next cluster-wide operation is performed which synchronizes the cluster state in any case). Note, please, when a module is deployed in cluster, it becomes “available” only after its deployment has been successfully completed by a Jahia processing node. For information and troubleshooting you could refer to a SSH console and “cluster:*” group of commands. The following command:

cluster:bundle-list default

shows the clustered state of bundles in the default group – the global cluster group, which includes all nodes. This command has a shortcut alias:


which does the same. Here is the sample snapshot of the output of this command:

In case of bundle state desynchronization in cluster, for example due to a cluster split (network partition) or other issues, it could be required to force synchronization of cluster state for bundles:

cluster:sync –bundle

or for all resources (bundles, config, features):


Module version update with limited downtime

Starting a new version of a module can take some time (from several seconds to few minutes), depending on its complexity, which will make the module unavailable during this operation, as well as the modules depending on it. This can be even more problematic when it involves a template set module: the consequence will be the unavailability of the sites using this template set during the start operation. The steps explaining how to perform a module deployment in a cluster with limited downtime are described in the "Module version update with limited downtime" procedure.

Module undeployment

You can undeploy your modules using REST API (or corresponding command-line script). Alternatively, you can undeploy the modules from the Administration > Server settings > System components > Modules screen. The advantage of doing so using the UI approach is that Jahia will inform you of any modules that might depend on the one you're trying to undeploy and will first ask you to disable the module from all the sites that might be using it. Module undeployment in both cases is a cluster-wide operation as described in Cluster deployment.

Deployment on sites

Once the JAR file has been deployed, modules become available. They can then be deployed to Web projects via module management screen in Server Settings or via Studio. If a new version of the module is uploaded on the server, it will be automatically deployed on all sites that are currently using it. All updates will be immediately available in the site.

  • have temporary data (Jahia caches, errors, thread and heap dumps) inside JBoss’ directory structure
  • in case the embedded Apache Derby DBMS is used, a Derby home must be set properly, pointing to the digital-factory-data/dbdata folder
  • further GC, thread and heap dump options, which we recommend
