Implementing Webservice client on websphere 8.0 - web-services

Question

I have a wsdl file, the clients files were generated and implemented in weblogic(6 years back).
Now, we are trying to implement in WAS 8.0, i generated the JAX-WS client classes and also developed the client. (we deleted all weblogic related jars)
But, i am receiving the following exception when running it,
[8/14/13 17:55:58:368 EDT] 0000001a DispatchActio E org.apache.struts.actions.DispatchAction dispatchMethod Dispatch[/scrflidverification] to method 'init' returned an exception

Answer 1

The (initialization failure) means that some prior error has occurred that is causing this class to not be loaded. Is there any additional Caused by: that you have not included? If not, I recommend looking elsewhere through your logs for a stack trace that includes WSATGenerator.<clinit>, which should have the original exception. If you can't find anything, then I recommend opening a PMR with IBM.
