I tried scoping the deployment of jmsra.jar by adding a <loader-repository> element to the jboss.xml file in the jar. It seems to deploy the jar in a scoped fashion: 2006-11-14 11:15:45,806 DEBUG [org.jboss.deployment.MainDeployer] Starting deployment of package: file:/home/rachmatowicz/jm\s-trunk/testsuite/output/lib/jmsra.jar 2006-11-14 11:15:45,806 DEBUG [org.jboss.deployment.MainDeployer] Starting deployment (init step) of package at: file:/home/\rachmatowicz/jms-trunk/testsuite/output/lib/jmsra.jar 2006-11-14 11:15:45,807 DEBUG [org.jboss.deployment.MainDeployer] Copying file:/home/rachmatowicz/jms-trunk/testsuite/output\/lib/jmsra.jar -> /home/rachmatowicz/jms-trunk/build/output/jboss-5.0.0.Beta/server/messaging/tmp/deploy/tmp50978jmsra.jar 2006-11-14 11:15:45,811 DEBUG [org.jboss.ejb3.deployment.EJB3ClientDeployer] accepts jmsra.jar 2006-11-14 11:15:45,866 DEBUG [org.jboss.deployment.MainDeployer] using deployer MBeanProxyExt[jboss.ejb:service=EJBDeployer\] 2006-11-14 11:15:45,866 DEBUG [org.jboss.ejb.EJBDeployer] init, jmsra.jar 2006-11-14 11:15:45,870 DEBUG [org.jboss.ejb.EJBDeployer] looking for nested deployments in : file:/home/rachmatowicz/jms-tr\unk/testsuite/output/lib/jmsra.jar 2006-11-14 11:15:45,872 DEBUG [org.jboss.deployment.DeploymentInfo] createLoaderRepository from config: LoaderRepositoryConf\ig(repositoryName: jboss.messaging:loader=ScopedLoaderRepository, repositoryClassName: org.jboss.mx.loading.HeirarchicalLoad\erRepository3, configParserClassName: org.jboss.mx.loading.HeirarchicalLoaderRepository3ConfigParser, repositoryConfig: java\2ParentDelegation=false) 2006-11-14 11:15:45,872 DEBUG [org.jboss.mx.loading.RepositoryClassLoader] setRepository, repository=org.jboss.mx.loading.He\irarchicalLoaderRepository3@178655, cl=org.jboss.mx.loading.UnifiedClassLoader3@205df9{ url=file:/home/rachmatowicz/jms-trun\k/build/output/jboss-5.0.0.Beta/server/messaging/tmp/deploy/tmp50978jmsra.jar ,addedOrder=0} 2006-11-14 11:15:45,873 DEBUG [org.jboss.mx.loading.RepositoryClassLoader] setRepository, repository=org.jboss.mx.loading.He\irarchicalLoaderRepository3@178655, cl=org.jboss.mx.loading.UnifiedClassLoader3@205df9{ url=file:/home/rachmatowicz/jms-trun\k/build/output/jboss-5.0.0.Beta/server/messaging/tmp/deploy/tmp50978jmsra.jar ,addedOrder=0} 2006-11-14 11:15:45,873 DEBUG [org.jboss.mx.loading.UnifiedLoaderRepository3] Adding org.jboss.mx.loading.UnifiedClassLoader\3@205df9{ url=file:/home/rachmatowicz/jms-trunk/build/output/jboss-5.0.0.Beta/server/messaging/tmp/deploy/tmp50978jmsra.jar \,addedOrder=0} 2006-11-14 11:15:45,877 DEBUG [org.jboss.deployment.MainDeployer] found 0 subpackages of file:/home/rachmatowicz/jms-trunk/t\estsuite/output/lib/jmsra.jar Thus, unless i'm doing something wrong, Messaging is deployed in a scoped fashion, the destinations used in tests are deployed in a scoped fashion, and the jmsra.jar is deployed in a scoped fashion. All scoping using the same loader-repository: ScopedLoaderRepository. But when the test is run, the same error appears. 11:15:46,279 INFO [EjbModule] Deploying PublisherCMP 11:15:46,428 INFO [EjbModule] Deploying JMSSession 11:15:46,453 INFO [EjbModule] Deploying QueuePublisher 11:15:46,465 INFO [EjbModule] Deploying TopicPublisher 11:15:46,477 INFO [EjbModule] Deploying QueueRec 11:15:46,485 INFO [EjbModule] Deploying TopicAdapter 11:15:47,453 INFO [ProxyFactory] Bound EJB Home 'PublisherCMP' to jndi 'PublisherCMP' 11:15:47,469 INFO [ProxyFactory] Bound EJB Home 'JMSSession' to jndi 'JMSSession' 11:15:47,488 INFO [ProxyFactory] Bound EJB Home 'QueuePublisher' to jndi 'TxPublisher' 11:15:47,496 INFO [ProxyFactory] Bound EJB Home 'TopicPublisher' to jndi 'TxTopicPublisher' 11:15:47,510 INFO [ProxyFactory] Bound EJB Home 'QueueRec' to jndi 'QueueRec' 11:15:48,959 INFO [EJBDeployer] Deployed: file:/home/rachmatowicz/jms-trunk/testsuite/output/lib/jmsra.jar 11:15:49,317 ERROR [ServerThread] failed to process invocation. java.io.OptionalDataException at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1316) at java.io.ObjectInputStream.readObject(ObjectInputStream.java:348) at org.jboss.remoting.serialization.impl.java.JavaSerializationManager.receiveObject(JavaSerializationManager.java:1\28) at org.jboss.remoting.marshal.serializable.SerializableUnMarshaller.read(SerializableUnMarshaller.java:66) at org.jboss.invocation.unified.marshall.InvocationUnMarshaller.read(InvocationUnMarshaller.java:48) at org.jboss.remoting.transport.socket.ServerThread.processInvocation(ServerThread.java:350) at org.jboss.remoting.transport.socket.ServerThread.dorun(ServerThread.java:398) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3985841#...
