Solution Verified - Updated

Environment

  • Red Hat JBoss Enterprise Application Platform (EAP)
    • 5.1.x
    • 5.2.0

Issue

  • How can I slim services from JBoss EAP 5.1 / 5.2?

    • Quartz scheduling package
    • hsqldb-ds.xml
    • sqlexception-service.xml

Resolution

  • If you have not yet removed HypersonicSQL, refer to How do I remove Hypersonic SQL database from JBoss EAP?
    Note: HypersonicSQL should not be used in a production environment. Please refer to This content is not included.Is Hypersonic (HSQLDB) supported in JBoss production environment ? about this.

  • If you do not want your JBoss instances to form a cluster, please refer to How do I disable clustering in JBoss EAP 5's "production" configuration?

  • If you do not need JMS functionality (provided via JBoss Messaging), remove:

    • $JBOSS_HOME/server/$PROFILE/deploy/messaging/

    • $JBOSS_HOME/server/$PROFILE/deploy/jms-ra.rar/

    • $JBOSS_HOME/server/$PROFILE/deployers/messaging-definitions-jboss-beans.xml

    • the following XAResourceRecovery.JBMESSAGING1 definition if it exists in $JBOSS_HOME/server/$PROFILE/conf/jbossts-properties.xml:

          <property name="com.arjuna.ats.jta.recovery.XAResourceRecovery.JBMESSAGING1"
       value="org.jboss.jms.server.recovery.MessagingXAResourceRecovery;java:/DefaultJMSProvider"/>

    • $JBOSS_HOME/server/$PROFILE/deploy/ejb3-connectors-jboss-beans.xml
    • $JBOSS_HOME/server/$PROFILE/deploy/ejb3-container-jboss-beans.xml
    • $JBOSS_HOME/server/$PROFILE/deploy/ejb3-interceptors-aop.xml
    • $JBOSS_HOME/server/$PROFILE/deploy/ejb3-timerservice-jboss-beans.xml
    • $JBOSS_HOME/server/$PROFILE/deployers/ejb3-deployers-jboss-beans.xml

    • $JBOSS_HOME/server/$PROFILE/deployers/jboss-ejb3-metrics-deployer.jar
    • $JBOSS_HOME/server/$PROFILE/deployers/ejb3.deployer/

    and add:

      <property name="persistenceUnitDependencyResolver"><null/></property>

    to the WarDeployer bean block in $JBOSS_HOME/server/$PROFILE/deployers/jbossweb.deployer/META-INF/war-deployers-jboss-beans.xml.

  • If you do not use EJB2, remove:

    • $JBOSS_HOME/server/$PROFILE/deploy/ejb2-container-jboss-beans.xml

      • $JBOSS_HOME/server/$PROFILE/deploy/ejb2-timer-service.xml

    Note: If you remove EJB 2.x/3.x but not remove web services (JBossWS), you need some additional steps. Please also refer to Removing dependence on EJB deployers from JBossWS deployer in JBoss EAP 5.1 for details.

    • $JBOSS_HOME/server/$PROFILE/deploy/ejb3-timerservice-jboss-beans.xml
    • $JBOSS_HOME/server/$PROFILE/deploy/ejb2-timer-service.xml
