It would be really convinient to make jboss WS and jsr-181 support Generics in a Webservice interface.
public ContentSet getContent()
public class ContentSet<T>
On Jboss 4.0.5 (jboss-ws 1.0.3), the generated wsdl does not generate the correct types and the webservice dos not work.
Comment from Thomas Diesler: his is not yet supported. You could create a feature request in jira.
