It deploys jaxws-endpoint-servlet.war. Hot-deploying the war seems to go through the deployer chain twice. Once, when it goes through usual hot-deployment (See Stack1 below), then it does something in the tomcat/service-layer, I guess to deploy the WS endpoint (See Stack2 below). Now the problem is that the first time it deploys this, it correctly includes a Module attachment with the deploymentunit which links the classloader to a scoped classloading domain called "vfszip:/Users/kabir/sourcecontrol/jbossas/Branch_5_0/testsuite/output/lib/jaxws-endpoint-servlet.war" (See variables1 below). When it deploys the second time, it incorrectly includes a Module attachment with the deploymentunit linking the classloader to the main/non-scoped classloading domain called DefaultDomain. Somehow the new deployment created internally needs to either include the original Module, or the correct classloading metadata to reuse the name "vfszip:/Users/kabir/sourcecontrol/jbossas/Branch_5_0/testsuite/output/lib/jaxws-endpoint-servlet.war". I think this happens around this point of Stack2: DynamicEndpointDeploymentAspect.create(Deployment) line: 88 DeploymentAspectManagerImpl.deploy(Deployment) line: 115 DeploymentAspectHttpServer.publish(HttpContext, Endpoint) line: 91 Since deployment 2 also passes through the AOPClassLoader deployer and it is getting the wrong information, AOP gets confused about the AOP domains used.
