    PrefixDeploymentSorter in Jboss 5

    fatbatman Novice


      How should I set the URLComparator to PrefixDeploymentSorter in JBoss5 beta 2?

      Thanks

            The PrefixDeploymentSorter pops up again in JBoss 6 (https://jira.jboss.org/jira/browse/JBAS-7614).

            I used this cass with JBoss 5 (added to lib/jboss-system.jar and modified conf/bootstrap/deployers.xml).

              What exactly did you change in the deployers.xml file? I copied the class into the jboss-system.jar file and change the class in the deployers.xml file but am getting a NullPointerException on deployment.

                I guess, he changed this:

                <!-- use legacy ordering -->
                   <bean name="topContextComparator">
                     <constructor factoryClass="org.jboss.system.deployers.LegacyDeploymentContextComparator" factoryMethod="getInstance"/>
                   </bean>
                

                 

                to

                 

                <!-- use legacy ordering -->
                   <bean name="topContextComparator">
                     <constructor factoryClass="org.jboss.system.deployers.LegacyPrefixDeploymentContextComparator" factoryMethod="getInstance"/>
                   </bean>

                  Yes, that's my change. I don't get an NPE with this change, but I tested only a little deployment which I use in a class.

                    Now I get the same NPE if I deploy an EAR with some JAR's. I described this also in the https://jira.jboss.org/jira/browse/JBAS-7614.

                     

                    If we change the bootstrap/deployers.xml in this way, the singelton instance of the LegacyDeploymentContextComparator doesn't exist (

                    who is used inside of a EAR).

                    In this case the AbstractStructureBuilder creates an new instance for the current deployment, but this instance of LegacyDeploymentContextComparator isn't initialized. This wil happen only during an lifecycle-callback ("create").

                     

                    To fix this, I added also the LegacyDeploymentContextComparator in the bootstrap/deployers.xml :

                     

                      <!-- use legacy ordering -->
                       <bean name="topContextComparator">
                         <constructor factoryClass="org.jboss.system.deployers.LegacyPrefixDeploymentContextComparator" factoryMethod="getInstance"/>
                       </bean>

                     

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

                     

                    in this case the singelton of the LegacyDeploymentContextComparator is created and used by nested deployments.

                      Thanks for getting back to me on this. I will give that a try.

                        I compiled a LegacyPrefixDeploymentContextComparator.class and put it into jboss-system.jar. After I've updated my deployers.xml I got this Exception:

                        Any ideas?

                         

                        Could anyone upload a working jboss-system.jar (with LegacyPrefixDeploymentContextComparator) to check if i made a misstake?

                         

                        Thanks in advance

                         

                        EDIT:

                        Found a misstake in my deployers.xml 

                        It seems to work!
