Installing Liferay DXP on JBoss EAP

Installing Liferay DXP on JBoss EAP 7.1 takes three steps:

• Installing Liferay DXP dependencies to your application server
• Configuring your application server for Liferay DXP
• Installing the Liferay DXP WAR file to your application server

Before proceeding, download these files for DXP or Portal CE:

• Liferay DXP WAR file
• Dependencies ZIP file
• OSGi JARs ZIP file

Liferay DXP requires a Java JDK 8 or 11.

Note: Please see the compatibility matrix for information on supported JDKs, databases, and environments.

Liferay Home is the folder containing your JBoss server folder. After installing and deploying Liferay DXP, the Liferay Home folder contains the JBoss server folder as well as data, deploy, logs, and osgi folders. $JBOSS_HOME refers to your JBoss server folder. This folder is usually named jboss-eap-[version].

Installing Dependencies

Liferay DXP depends on several Liferay-specific and third-party JARs. Download and install the required JARs as described below.

1. Create the folder $JBOSS_HOME/modules/com/liferay/portal/main if it doesn’t exist and extract the Liferay dependencies ZIP JARs to it.

2. Download your database driver .jar file and copy it into the same folder. Please see the compatibility matrix for a list of supported databases.

3. Create the file module.xml in the $JBOSS_HOME/modules/com/liferay/portal/main folder. In the file, declare the portal module and all of its required resources and dependencies:

   <?xml version="1.0"?>
   
   <module xmlns="urn:jboss:module:1.0" name="com.liferay.portal">
       <resources>
           <resource-root path="[place your database vendor's JAR file name here]" />
           <resource-root path="[place a Liferay dependencies JAR file name here]" />
           <!-- Add a resource-root element for each Liferay dependencies JAR -->
       </resources>
       <dependencies>
           <module name="javax.api" />
           <module name="javax.mail.api" />
           <module name="javax.servlet.api" />
           <module name="javax.servlet.jsp.api" />
           <module name="javax.transaction.api" />
       </dependencies>
   </module>
   

   Replace [place your database vendor's JAR file name here] with the driver JAR for your database.

   For each JAR in the Liferay dependencies ZIP, add a resource-root element with its path attribute set to the JAR name. For example, add a resource-root element like this for the com.liferay.petra.concurrent.jar file:

   <resource-root path="com.liferay.petra.concurrent.jar" />
   

4. Create an osgi folder in your Liferay Home folder. Extract the OSGi ZIP file that you downloaded into the osgi folder.

   The osgi folder provides the necessary modules for Liferay DXP’s OSGi runtime.

Checkpoint:

1. The dependencies files have been unzipped into the $JBOSS_HOME/modules/com/liferay/portal/main folder and a database jar.
2. The module.xml contains all JARs in the <resource-root-path> elements.
3. The osgi dependencies have been unzipped into the osgi folder.

Running Liferay DXP on JBoss EAP in Standalone Mode vs. Domain Mode

JBoss EAP can be launched in either standalone mode or domain mode. Domain mode allows multiple application server instances to be managed from a single control point. A collection of such application servers is known as a domain. For more information on standalone mode vs. domain mode, please refer to the section on this topic in the JBoss EAP Product Documentation.

Liferay DXP supports JBoss EAP when it runs in standalone mode but not when it runs in domain mode. Liferay DXP’s hot-deploy does not work with a managed deployment, since JBoss manages the content of a managed deployment by copying files (exploded or non-exploded). This prevents JSP hooks and Ext plugins from working as intended. For example, JSP hooks don’t work on JBoss EAP running in managed domain mode, since Liferay DXP’s JSP override mechanism relies on the application server. Since both of these features are deprecated, however, you may not be using them.

The command line interface is recommended for domain mode deployments.

Note: This does not prevent Liferay DXP from running in a clustered environment on multiple JBoss servers. You can set up a cluster of Liferay DXP instances running on JBoss EAP servers running in standalone mode. Please refer to the Liferay DXP Clustering section for information on setting up a Liferay DXP cluster.

Configuring JBoss

Configuring JBoss to run Liferay DXP includes these things:

• Setting environment variables
• Setting properties and descriptors
• Removing unnecessary configurations

Optionally, you can configure JBoss to manage these things for Liferay DXP:

• Data source
• Mail session

Start with configuring JBoss to run Liferay DXP.

Make the following modifications to $JBOSS_HOME/standalone/configuration/standalone.xml:

1. In the <jsp-configuration> tag, set the Java VM compatibility for Liferay source and class files. They are compatible with Java 8 by default.

   <jsp-configuration development="true" source-vm="1.8" target-vm="1.8" />
   

2. Locate the closing </extensions> tag. Directly beneath that tag, insert these system properties:

   <system-properties>
       <property name="org.apache.catalina.connector.URI_ENCODING" value="UTF-8" />
       <property name="org.apache.catalina.connector.USE_BODY_ENCODING_FOR_QUERY_STRING" value="true" />
   </system-properties>
   

3. Add the following <filter-spec> tag within the <console-handler> tag, directly below the <level name="INFO"/> tag:

   <filter-spec value="not(any(match(&quot;WFLYSRV0059&quot;),match(&quot;WFLYEE0007&quot;)))" />
   

4. Add a timeout for the deployment scanner by setting deployment-timeout="360" as seen in the excerpt below.

   <subsystem xmlns="urn:jboss:domain:deployment-scanner:2.0">
       <deployment-scanner deployment-timeout="360" path="deployments" relative-to="jboss.server.base.dir" scan-interval="5000"/>
   </subsystem>
   

5. Add the following JAAS security domain to the security subsystem <security-domains> defined in element <subsystem xmlns="urn:jboss:domain:security:2.0">.

   <security-domain name="PortalRealm">
       <authentication>
           <login-module code="com.liferay.portal.kernel.security.jaas.PortalLoginModule" flag="required" />
       </authentication>
   </security-domain>
   

6. Remove the two code snippets providing welcome content:

   <location name="/" handler="welcome-content"/>
   

   and

   <handlers>
       <file name="welcome-content" path="${jboss.home.dir}/welcome-content"/>
   </handlers>
   

7. Find the <jsp-config/> tag and set the development, source-vm, and target-vm attributes in the tag. Once finished, the tag should look like this:

   <jsp-config development="true" source-vm="1.8" target-vm="1.8"/>
   

Checkpoint:

Before continuing, verify the following properties have been set in the standalone.xml file:

1. The new <system-property> is added.

2. The new <filter-spec> is added.

3. The <deployment-timeout> is set to 360.

4. The new <security-domain> is created.

5. Welcome content is removed.

6. The <jsp-config> tag contains its new attributes.

Now you should configure your JVM and startup scripts.

In the $JBOSS_HOME/bin folder, you must make these modifications to your standalone domain’s configuration script file standalone.conf (standalone.conf.bat on Windows):

• Set the file encoding to UTF-8
• Set the user time zone to GMT
• Set the preferred protocol stack
• Increase the default amount of memory available.

Important: For Liferay DXP to work properly, the application server JVM must use the GMT time zone and UTF-8 file encoding.

Make the following edits as applicable to your operating system:

Windows

1. Comment out the initial JAVA_OPTS assignment as demonstrated in the following line:

   rem set "JAVA_OPTS=-Xms1G -Xmx1G -XX:MetaspaceSize=96M -XX:MaxMetaspaceSize=256m"
   

2. Add the following JAVA_OPTS assignment one line above the :JAVA_OPTS_SET line found at end of the file:

   set "JAVA_OPTS=%JAVA_OPTS% -Dfile.encoding=UTF-8 -Djava.net.preferIPv4Stack=true -Djboss.as.management.blocking.timeout=480 -Duser.timezone=GMT -Xmx2048m -XX:MaxMetaspaceSize=384m"
   

Unix

1. Below the if [ "x$JAVA_OPTS" = "x" ]; statement, replace this JAVA_OPTS statement:

   JAVA_OPTS="-Xms1303m -Xmx1303m -XX:MetaspaceSize=96M -XX:MaxMetaspaceSize=256m -Djava.net.preferIPv4Stack=true
   

   with this:

   JAVA_OPTS="-Djava.net.preferIPv4Stack=true"
   

2. Add the following statement to the bottom of the file:

   JAVA_OPTS="$JAVA_OPTS -Dfile.encoding=UTF-8 -Djava.net.preferIPv4Stack=true -Djboss.as.management.blocking.timeout=480 -Duser.timezone=GMT -Xmx2048m -XX:MaxMetaspaceSize=512m"
   

Important: On JDK 11, the setting -Djava.locale.providers=JRE,COMPAT,CLDR is required to display four-digit years. Since JDK 9, the Unicode Common Locale Data Repository (CLDR) is the default locales provider. CLDR does not provide years in a four-digit format (see LPS-87191). This setting works around the issue by using JDK 8’s default locales provider.

Note: If you plan on using the IBM JDK with your JBoss server, you must complete some additional steps. First, navigate to the $JBOSS_HOME/modules/com/liferay/portal/main/module.xml file and insert the following dependency within the <dependencies> element:

<module name="ibm.jdk" />

Then navigate to the $JBOSS_HOME/modules/system/layers/base/sun/jdk/main/module.xml file and insert the following path names inside the <paths>...</paths> element:

<path name="com/sun/crypto" />
<path name="com/sun/crypto/provider" />
<path name="com/sun/image/codec/jpeg" />
<path name="com/sun/org/apache/xml/internal/resolver" />
<path name="com/sun/org/apache/xml/internal/resolver/tools" />

The added paths resolve issues with portal deployment exceptions and image uploading problems.

Checkpoint:

At this point, you’ve finished configuring the application server’s JVM settings.

1. The file encoding, user time-zone, preferred protocol stack have been set in the JAVA_OPTS in the standalone.conf.bat file.

2. The default amount of memory available has been increased.

The prescribed script modifications are now complete for your Liferay DXP installation on JBoss. Next you’ll configure the database and mail.

Database Configuration

The easiest way to handle your database configuration is to let Liferay DXP manage your data source. The Basic Configuration page lets you configure Liferay DXP’s built-in data source. If you want to use the built-in data source, skip this section.

If you want JBoss to manage your data source, follow these steps:

1. Add the data source inside the $JBOSS_HOME/standalone/configuration/standalone.xml file’s the <datasources> element.

   <datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="true" jta="true" use-java-context="true" use-ccm="true">
       <connection-url>[place the URL to your database here]</connection-url>
       <driver>[place the driver name here]</driver>
       <security>
           <user-name>[place your user name here]</user-name>
           <password>[place your password here]</password>
       </security>
   </datasource>
   

   Make sure to replace the database URL, user name, and password with the appropriate values.

   Note: If you must change your datasource jndi-name to something different, you must also edit the datasource element in the <default-bindings> tag.

2. Add the driver to the standalone.xml file’s <drivers> element also found within the <datasources> element.

   <drivers>
       <driver name="[name of driver must match name above]" module="com.liferay.portal">
           <driver-class>[place your JDBC driver class here]</driver-class>
       </driver>
   </drivers>
   

   A final data source subsystem that uses MySQL should look like this:

   <subsystem xmlns="urn:jboss:domain:datasources:5.0">
       <datasources>
           <datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="true" jta="true" use-java-context="true" use-ccm="true">
               <connection-url>jdbc:mysql://localhost/lportal</connection-url>
               <driver>mysql</driver>
               <security>
                   <user-name>root</user-name>
                   <password>root</password>
               </security>
           </datasource>
           <drivers>
               <driver name="mysql" module="com.liferay.portal"/>
           </drivers>
       </datasources>
   </subsystem>
   

3. In a portal-ext.properties file in your Liferay Home, specify your data source:

   jdbc.default.jndi.name=java:jboss/datasources/ExampleDS
   

Now that you’ve configured your data source, the mail session is next.

Mail Configuration

As with database configuration, the easiest way to configure mail is to let Liferay DXP handle your mail session. If you want to use Liferay DXP’s built-in mail session, skip this section and configure the mail session in the Control Panel.

If you want to manage your mail session with JBoss, follow these steps:

1. Specify your mail subsystem in the $WILDFLY_HOME/standalone/configuration/standalone.xml file like this:

   <subsystem xmlns="urn:jboss:domain:mail:3.0">
       <mail-session jndi-name="java:jboss/mail/MailSession" >
           <smtp-server ssl="true" outbound-socket-binding-ref="mail-smtp">
               <login username="USERNAME" password="PASSWORD"/>
           </smtp-server>
      </mail-session>
   </subsystem>
   ...
   <socket-binding-group name="standard-sockets" default-interface="public" port-offset="${jboss.socket.binding.port-offset:0}">
   ...
   <outbound-socket-binding name="mail-smtp">
           <remote-destination host="smtp.gmail.com" port="465"/>
       </outbound-socket-binding>
   </socket-binding-group>
   

2. In your portal-ext.properties file in Liferay Home, reference your mail session:

   mail.session.jndi.name=java:jboss/mail/MailSession
   

You’ve got mail! Next, you’ll deploy Liferay DXP to your JBoss app server.

Deploying Liferay DXP

1. If the folder $JBOSS_HOME/standalone/deployments/ROOT.war already exists in your JBoss installation, delete all of its subfolders and files. Otherwise, create a new folder called $JBOSS_HOME/standalone/deployments/ROOT.war.

2. Unzip the Liferay DXP .war file into the ROOT.war folder.

3. To trigger deployment of ROOT.war, create an empty file named ROOT.war.dodeploy in your $JBOSS_HOME/standalone/deployments/ folder. On startup, JBoss detects the presence of this file and deploys it as a web application.

4. Start the JBoss application server by navigating to $JBOSS_HOME/bin and running standalone.bat or standalone.sh.

Congratulations; you’ve now deployed Liferay DXP on JBoss!

After deploying Liferay DXP, you may see excessive warnings and log messages, such as the ones below, involving PhaseOptimizer. These are benign and can be ignored. Make sure to adjust your app server’s logging level or log filters to avoid excessive benign log messages.
