In that case a wsdl like this | <types> | <schema ...> | <complexType name="paraListType"> | <sequence> | <element name="username" type="string" nillable="true"/> | <element name="password" type="string" nillable="true"/> | <element name="operationName" type="string" nillable="true"/> | <element name="inputXML" type="string" nillable="true"/> | </sequence> | </complexType> | <complexType name="responseType"> | <sequence> | <element name="result" type="string" nillable="true"/> | </sequence> | </complexType> | <element name="paraList2" type="tns:paraListType"/> | <element name="responseXML" type="tns:responseType"/> | </schema> | </types> | <message name="attachRequest"> | <part name="parameters" element="ns2:paraList2"/> | <part name="attachmentContents" type="xsd:string"/> | </message> | <message name="attachResponse"> | <part name="result" element="ns2:responseXML"/> | </message> | <portType name="TransmulatorInterface"> | <operation name="invokeAttach"> | <input message="tns:attachRequest"/> | <output message="tns:attachResponse"/> | </operation> | </portType> | should work and the generated java method name should be paraList2 instead of invokeAttach. AFAICS the requriment pertains only the the java realm and not to the abstract contract in wsdl. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4000885#...
