"Possible redeploy issue" To view the discussion, visit: http://community.jboss.org/message/551692#551692 -------------------------------------------------------------- Hi, I've got an issue with redployment of a JBoss ESB service. This service uses a feature in JBoss ESB that creates a web service for the service automatically when the .esb archive is deployed. Redploying the .esb archive by touching it or replacing it is not an problem and works just as expected and it will redeploy cleanly. The problem I have is when I specify that the .esb archive depends on another deployment using the jboss-classloading features in JBoss AS 5.1.0. The use case I have is that I have two deployments, domain-model-1.0.0.jar and service1-1.0.esb. domain-model-1.0.0.jar has a jboss-classloading.xml that looks like this: <classloading xmlns="urn:jboss:classloading:1.0" export-all="NON_EMPTY"> <capabilities> <module name="domain-model" version="${version}"/> </capabilities> </classloading> service1-1.0.esb has a jboss-classloading.xml that looks like this: <classloading xmlns="urn:jboss:classloading:1.0" import-all="true"> <requirements> <module name="domain-model" version="${domain.model.version}"/> </requirements> </classloading> When I redploy domain-model-1.0.0.jar I get the following error: 13:53:34,102 INFO [TomcatDeployment] undeploy, ctxPath=/service1-1.0 13:53:34,328 INFO [QueueService]

I've looked through some of the code and one thing that I noticed was this section in org.jboss.wsf.container.jboss50.deployer.ArchiveDeployerHook and its deploy method: public void deploy(DeploymentUnit unit) throws DeploymentException { if (ignoreDeployment(unit)) return; if (isWebServiceDeployment(unit)) { log.debug("deploy: " + unit.getName()); Deployment dep = getDeployment(unit); if (dep == null) { dep = createDeployment(unit); dep.addAttachment(DeploymentUnit.class, unit); } unit.addAttachment(Deployment.class, dep); getDeploymentAspectManager().deploy(dep); } } What I'm seeing is that when the error occurs getDeployment returns a deployment instance and its initialClassLoader will be that of the previous deployment. Later when WebMetaDataModifierImpl gets called it will use the old classloader which you can see is part of the stacktrace above. One thing that I noticed was that the state of the deployment instance returned from getDeployment is DeploymentState.DESTROYED. I added a check for this and redployment works fine after that: if (dep == null || dep.getState() == DeploymentState.DESTROYED) I'm not familiar with the code base and I'm not saying this is a solution but perhaps this might give someone a hint of what the issue is and why it is happening. I'll attach the use case that I've been using if anyone wants to reproduce this.
