We are facing similar issue for our production setup. The details are as follows:
1. JBoss SOA Platform: Embedded Server - Version 5.1.0.GA
2. Scenario - Parallel invocations of JAX WS services
3. Exception - javax.xml.ws.WebServiceException: java.lang.ClassCastException
4. Native versions – bundled with AS, jbossws-native-3.1.2.SP7
I tried installing jbossws-native-3.4.1.GA onto my server and deployment completed successfully. But the server refuses to start with following error:
java.lang.SecurityException: class "org.jboss.metadata.MetaData"'s signer information does not match signer information of other classes in the same package
Kindly suggest how to proceed with the fix.
