Hi Ole, Sorry for the confusion, but I didn't mean to expose overloaded Java methods in the service endpoint interface. In my case, I want to publish POJO webservice, which has a single Java method that takes abstract parameter and returns abstract return value as follow: public WSAbstractReturnValue getValueBy(WSAbstractParameter paramter); And, I have two subclasses for each of the abstract types: public class WSReturnImplOne extends WSAbstractReturnValue {} public class WSReturnImplTwo extends WSAbstractReturnValue {} public class WSParameterImplOne extends WSAbstractParameter {} public class WSParameterImplTwo extends WSAbstractParameter {} I want that the client may call the service method with a parameter of arbitrary subtype, and the service method may also return arbitrary subtype. By simply using steps from the bottom-up example (http://www.soapui.org/jbossws/bottomup.html) for my POJO, first, I didn't find expected elements for the derived types in the generated WSDL file. Hence, I didn't get the corresponding client artifacts when following the next walkthrough example (http://www.soapui.org/jbossws/consume.html). If I use the wstools directly, running the wstools command against a config file, is there a way to specify the subclasses in the configuration file? On top of that, is there a way to specify the subclasses through the plugin dialogs? Thanks, Kalvin View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3981538#...
