We are still stuck into this. It's a new project so we tried to write the server with different vendors. AFAIK for WS which returns arrays JBossWS seems to be able to generate a client only for WSDL generated from a JBossWS stack. Comparing different WSDL, I saw that when array comes in, other vendors generates the WSDL in this way: <s:complexType> while JBossWS: <complexType name="String.Array"> So the WSTOOLS complain about the anonymous wrote : String passed is null When do you foresee a new version?
