DBMessageStoreImpl not able to deserilize objects due to what appears to be a classloader/scoping issue ------------------------------------------------------------------------------------------------------- Key: JBESB-1215 URL: http://jira.jboss.com/jira/browse/JBESB-1215 Project: JBoss ESB Issue Type: Bug Security Level: Public (Everyone can see) Components: Message Store Affects Versions: 4.2.1 IR2 Reporter: Tom Fennelly Assigned To: Kurt Stam Fix For: 4.2.1 triage I see this issue when running the deadletter quickstart. DBMessageStoreImpl is trying to deserialize org.jboss.internal.soa.esb.message.format.serialized.MessageImpl through Base64.decodeToObject (actually, I guess it could be could be some other class that has MessageImpl as a property, but I doubt that). Base64.decodeToObject uses ObjectInputStream, which resolves the class using the "latestUserDefinedLoader". Not sure what that is coz latestUserDefinedLoader is a native method and the javadoc means nothing to me :-) Whatever latestUserDefinedLoader is, it's not the TCCL coz I added test code to DBMessageStoreImpl and it's able to load the class through the TCCL. Here's the stack trace I see... 10:03:59,578 ERROR [STDERR] java.lang.ClassNotFoundException: org.jboss.internal.soa.esb.message.format.serialized.MessageImpl 10:03:59,578 ERROR [STDERR] at java.net.URLClassLoader$1.run(URLClassLoader.java:200) 10:03:59,578 ERROR [STDERR] at java.security.AccessController.doPrivileged(Native Method) 10:03:59,578 ERROR [STDERR] at java.net.URLClassLoader.findClass(URLClassLoader.java:188) 10:03:59,578 ERROR [STDERR] at java.lang.ClassLoader.loadClass(ClassLoader.java:306) 10:03:59,578 ERROR [STDERR] at java.lang.ClassLoader.loadClass(ClassLoader.java:251) 10:03:59,578 ERROR [STDERR] at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:319) 10:03:59,578 ERROR [STDERR] at java.lang.Class.forName0(Native Method) 10:03:59,578 ERROR [STDERR] at java.lang.Class.forName(Class.java:242) 10:03:59,578 ERROR [STDERR] at java.io.ObjectInputStream.resolveClass(ObjectInputStream.java:585) 10:03:59,578 ERROR [STDERR] at java.io.ObjectInputStream.readNonProxyDesc(ObjectInputStream.java:1544) 10:03:59,593 ERROR [STDERR] at java.io.ObjectInputStream.readClassDesc(ObjectInputStream.java:1466) 10:03:59,593 ERROR [STDERR] at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1699) 10:03:59,593 ERROR [STDERR] at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1305) 10:03:59,593 ERROR [STDERR] at java.io.ObjectInputStream.readObject(ObjectInputStream.java:348) 10:03:59,593 ERROR [STDERR] at org.jboss.util.Base64.decodeToObject(Base64.java:864) 10:03:59,593 ERROR [STDERR] at org.jboss.internal.soa.esb.persistence.format.db.DBMessageStoreImpl.getAllMessages(DBMessageStoreImpl.java:278) 10:03:59,593 ERROR [STDERR] at org.jboss.soa.esb.samples.quickstart.deadletter.MyFailingSyncAction.process(MyFailingSyncAction.java:69) 10:03:59,609 ERROR [STDERR] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) 10:03:59,609 ERROR [STDERR] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) 10:03:59,609 ERROR [STDERR] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) 10:03:59,609 ERROR [STDERR] at java.lang.reflect.Method.invoke(Method.java:585) 10:03:59,609 ERROR [STDERR] at org.jboss.soa.esb.listeners.message.ActionProcessorMethodInfo.processMethods(ActionProcessorMethodInfo.java:102) 10:03:59,609 ERROR [STDERR] at org.jboss.soa.esb.listeners.message.OverriddenActionLifecycleProcessor.process(OverriddenActionLifecycleProcessor.java:74) 10:03:59,609 ERROR [STDERR] at org.jboss.soa.esb.listeners.message.ActionProcessingPipeline.process(ActionProcessingPipeline.java:273) 10:03:59,609 ERROR [STDERR] at org.jboss.soa.esb.listeners.message.MessageAwareListener$1.run(MessageAwareListener.java:303) 10:03:59,609 ERROR [STDERR] at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:650) 10:03:59,609 ERROR [STDERR] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:675) 10:03:59,625 ERROR [STDERR] at java.lang.Thread.run(Thread.java:595) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
