Cannot find PrefixDeploymentSorter for controlling deployment ordering in JBoss EAP

Solution Verified - Updated -

Environment

  • JBoss Enterprise Application Platform (EAP)
    • 5.0.0_GA
    • 5.0.1
    • 5.1.0

Issue

In JBoss.org 4.x we set the URLComparator attribute to 'org.jboss.deployment.scanner.PrefixDeploymentSorter' in the URLDeploymentScanner mbean to control the deployment ordering.  But, the PrefixDeploymentSorter does not appear available any longer.

Resolution

EAP 5.1.x

The PrefixDeploymentSorter is already enabled in <jboss-home>/server/<server-dir>/conf/bootstrap/deployer.xml

EAP 5.0.1

The PrefixDeploymentSorter was not included in EAP 5.0.0_GA.  However, introduction of the functionality through the LegacyPrefixDeploymentContextComparator is included in EAP 5.0.1.

To use the LegacyPrefixDeploymentContextComparator modify the <jboss-home>/server/<server-dir>/conf/bootstrap/deployers.xml and set the LegacyPrefixDeploymentContextComparator as the topContextComparator bean:

<bean name="topContextComparator">
    <constructor factoryClass="org.jboss.system.deployers.LegacyPrefixDeploymentContextComparator" factoryMethod="getInstance"/>
</bean>

There is  a bug in the LegacyDeploymentContextComparator on which the LegacyPrefixDeploymentContextComparator is a subclass.  This bug is corrected in EAP 5.1.  But, for EAP 5.0.1,  you will need to either define a LegacyDeploymentContextComparator bean:

<bean name="legacyContextComparator">
    <constructor factoryClass="org.jboss.system.deployers.LegacyDeploymentContextComparator" factoryMethod="getInstance"/>
</bean>

or configure the use of the LegacyPrefixDeploymentContextComparator in the <jboss-home>/server/<server-dir>/deployers/ear-deployer-jboss-beans.xml for the EARStructureDeployer's comparatorClassName property:

<deployment xmlns="urn:jboss:bean-deployer:2.0">
   <bean name="EARStructureDeployer" class="org.jboss.deployment.EARStructure">
     <property
name="comparatorClassName">org.jboss.system.deployers.LegacyPrefixDeploymentContextComparator</property>
     ...

EAP 5.0.0

The PrefixDeploymentSorter is not included
