Problem with Classloading Isolation in JBoss 7.0.1 -------------------------------------------------- Key: AS7-2533 URL: https://issues.jboss.org/browse/AS7-2533 Project: Application Server 7 Issue Type: Bug Affects Versions: 7.0.1.Final Environment: Windows XP SP3, Eclipse Indigo SR1, Sun JDK 1.6.0_24 Reporter: Silvana Sadewasser Attachments: multimodule.zip Hi all, this is related to an problem already discussed in the forums, but not solved. See below or http://community.jboss.org/thread/173458 Cheers, Gnu ____________________________ Hi all, I have created an (Java EE 6) EAR project with two WAR projects within my Eclipse Indigo. Each web module contains only one simple bean with the same name and the @Named annotation attached. Each web module has an empty beans.xml, too. (Hot-)deploying this EAR to my local JBoss 7.0.1 default instance causes the following error indicating that the classloader isolation in JBoss 7 does not work correctly. 10:59:54,723 INFO [org.jboss.weld] (MSC service thread 1-1) Processing CDI deployment: multimodule-ear.ear 10:59:54,785 INFO [org.jboss.weld] (MSC service thread 1-7) Processing CDI deployment: multimodule-war2.war 10:59:54,785 INFO [org.jboss.weld] (MSC service thread 1-10) Processing CDI deployment: multimodule-war1.war 10:59:54,801 INFO [org.jboss.weld] (MSC service thread 1-9) Starting Services for CDI deployment: multimodule-ear.ear 10:59:54,864 INFO [org.jboss.weld.Version] (MSC service thread 1-9) WELD-000900 1.1.2 (Final) 10:59:54,879 INFO [org.jboss.weld] (MSC service thread 1-7) Starting weld service 10:59:56,192 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-7) MSC00001: Failed to start service jboss.deployment.unit."multimodule-ear.ear".WeldService: org.jboss.msc.service.StartException in service jboss.deployment.unit."multimodule-ear.ear".WeldService: org.jboss.weld.exceptions.DeploymentException: WELD-001414 Bean name is ambiguous.

Can you tell me, why this error then occurs and how I can prevent from it? Thanks for your reply in advance.
