Hi folks, I would like switch our "myapplication.ear" from 4.0.3SP1 to JBoss 5.0.1GA, but the deployment fails into JBoss5. Into the shell an error occured while the jboss startup. The error is a ClassNotFoundException, but I havn't this class. The deployment from the same ear-file at 4.0.3SP1 produced zero errors at the startup. Can you're help me? Thanks Tino ... 15:03:15,531 ERROR [AbstractKernelController] Error installing to PostClassLoader: name=vfszip:/home/trudolph/hyptest/dev/jboss-5.0.1.GA/server/5.1/deploy/myapplication.ear/ state=ClassLoader mode=Manual requiredState=PostClassLoader org.jboss.deployers.spi.DeploymentException: Cannot process metadata at org.jboss.deployers.spi.DeploymentException.rethrowAsDeploymentException(DeploymentException.java:49) at org.jboss.deployment.AnnotationMetaDataDeployer.deploy(AnnotationMetaDataDeployer.java:181) at org.jboss.deployment.AnnotationMetaDataDeployer.deploy(AnnotationMetaDataDeployer.java:93) at org.jboss.deployers.plugins.deployers.DeployerWrapper.deploy(DeployerWrapper.java:171) at org.jboss.deployers.plugins.deployers.DeployersImpl.doDeploy(DeployersImpl.java:1439) at org.jboss.deployers.plugins.deployers.DeployersImpl.doInstallParentFirst(DeployersImpl.java:1157) at org.jboss.deployers.plugins.deployers.DeployersImpl.install(DeployersImpl.java:1098) at org.jboss.dependency.plugins.AbstractControllerContext.install(AbstractControllerContext.java:348) at org.jboss.dependency.plugins.AbstractController.install(AbstractController.java:1598) at org.jboss.dependency.plugins.AbstractController.incrementState(AbstractController.java:934) at org.jboss.dependency.plugins.AbstractController.resolveContexts(AbstractController.java:1062) at org.jboss.dependency.plugins.AbstractController.resolveContexts(AbstractController.java:984) at org.jboss.dependency.plugins.AbstractController.change(AbstractController.java:822) at org.jboss.dependency.plugins.AbstractController.change(AbstractController.java:553) at org.jboss.deployers.plugins.deployers.DeployersImpl.process(DeployersImpl.java:781) at org.jboss.deployers.plugins.main.MainDeployerImpl.process(MainDeployerImpl.java:698) at org.jboss.system.server.profileservice.ProfileServiceBootstrap.loadProfile(ProfileServiceBootstrap.java:304) at org.jboss.system.server.profileservice.ProfileServiceBootstrap.start(ProfileServiceBootstrap.java:205) at org.jboss.bootstrap.AbstractServerImpl.start(AbstractServerImpl.java:405) at org.jboss.Main.boot(Main.java:209) at org.jboss.Main$1.run(Main.java:547) at java.lang.Thread.run(Thread.java:595) Caused by: java.lang.ClassNotFoundException: com.test.MyTest from BaseClassLoader@1c43566{VFSClassLoaderPolicy@8dcfef{name=vfszip:/home/trudolph/hyptest/dev/jboss-5.0.1.GA/server/5.1/deploy/hyperdoc.ear/ domain=ClassLoaderDomain@185ad79{name=DefaultDomain parentPolicy=BEFORE parent=org.jboss.system.NoAnnotationURLClassLoader@fa7e74} roots=[MemoryContextHandler@5142027[path= context=vfsmemory://3j011-8k9c0l-frxiar4s-1-frxicajm-1z real=vfsmemory://3j011-8k9c0l-frxiar4s-1-frxicajm-1z] ......
