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 tired 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.  -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/730465#730465] Start a new discussion in JBoss Web Services Development at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
