Taking the following two elements as the input and ouput parameters: - <element name='lookup'> | <complexType> | <sequence> | <element name='firstName' nillable='true' type='string'/> | <element name='surname' nillable='true' type='string'/> | </sequence> | </complexType> | </element> | | <element name='lookupResponse'> | <complexType> | <sequence> | <element name='areaCode' nillable='true' type='string'/> | <element name='number' nillable='true' type='string'/> | </sequence> | </complexType> | </element> wscompile is generating the SEI method as: - public org.jboss.test.ws.jbws1260.LookupResponse lookup(java.lang.String firstName, java.lang.String surname) throws java.rmi.RemoteException; So the input element is being unwrapped as it can be converted to seperate parameters, however the return type can not be unwrapped so it is not. The JAX-RPC 1.1 specification doesn't seem to say how this should be handled. Previously we were dropping the second element in the return type and would just return a String. Tha JAX-WS spec seems to clarify this by mapping the wrapper children as a parameter using a holder type. Which approach should we be taking, especially as we don't currently generate holders?
