[jboss-user] [Installation, Configuration & DEPLOYMENT] - Scoped ClassLoading + commons-collections.jar

Dear JBoss Users, I am trying to migrate a war-application (that was already running on Tomcat) to JBoss5.1.0GA. After some revaluation of my web.xml file and some fighting with JBoss-classloading it is finally possible to deploy it. Yippee! BUT! Now I have a following problem while running the application: | java.lang.NoSuchMethodError: org.apache.commons.collections.CollectionUtils.isNotEmpty(Ljava/util/Collection;)Z | After some "investigation" I've found, that it's because of the jboss-5.1.0.GA/common/lib/commons-collections.jar version is prior to 3.2. My application is however configured for the isolated classloading by the "jboss-classloading.xml": | <?xml version="1.0" encoding="UTF-8"?> | | <classloading xmlns="urn:jboss:classloading:1.0" | name="reportal.war" | domain="MyWar_Domain" | export-all="NON_EMPTY" | import-all="false"> | </classloading> | Thats why I would expect my application to use a commons-collections-3.2.jar from WEB-INF/lib folder within the application war folder. What obviously is not the case. Replacing the jboss-5.1.0.GA/common/lib/commons-collections.jar with a newer version solves the problem. It is though not really a preferred option cause of the requirement I have - in an optimal way there should be as less customization on JBoss as possible. The question now is: Why isn't the applications own commons-collections.jar loaded? How do I can achieve it?
