    Problems with Web Services on JBoss 4.2.1

    chui

      Hi there!

      I'm trying to run my application with JBoss AS 4.2.1, but I found some strange differences between 4.2.1 and 4.0.5 (which I was using before). It seems like JBoss 4.2.1 uses default values or default manners of naming everything!! Examples:

      1-) With 4.0.5 I was using the namespace http://endpoints/jaws/ and everything was ok. But with 4.2.1, the operations' namespace comes from the package where the classes are. If I put my endpoint interfaces in a package "endpoints.jaws", I just can't call the service's methods because the operations' namespace becomes "http://jaws.endpoints". I avoided this error by changing my namespace to a simple "http://endpoints/" and putting the interfaces in the package "endpoints"... (But I'd like to know if it's possible to keep using http://endpoints/jaws, or JBoss 4.0.5 won't allow the deployment of these services anymore... =/)

      2-) Well, when I changed the namespace, the webservices were available on JBossWS... and I got stuck. This is the error I receive:

      As you can see, my WSDL file doesn't have this part name "arg0":

      <?xml version="1.0" encoding="UTF-8"?>
      <definitions name='Commands' targetNamespace='http://endpoints/' xmlns='http://schemas.xmlsoap.org/wsdl/' xmlns:soap='http://schemas.xmlsoap.org/wsdl/soap/' xmlns:tns='http://endpoints/' xmlns:xsd='http://www.w3.org/2001/XMLSchema'>
       <types/>
       <message name='Commands_execute'>
       <part name='String_1' type='xsd:string'/>
       </message>
       <message name='Commands_executeResponse'>
       <part name='result' type='xsd:string'/>
       </message>
       <portType name='Commands'>
       <operation name='execute' parameterOrder='String_1'>
       <input message='tns:Commands_execute'/>
       <output message='tns:Commands_executeResponse'/>
       </operation>
       </portType>
       <binding name='CommandsBinding' type='tns:Commands'>
       <soap:binding style='rpc' transport='http://schemas.xmlsoap.org/soap/http'/>
       <operation name='execute'>
       <soap:operation soapAction=''/>
       <input>
       <soap:body namespace='http://endpoints/' use='literal'/>
       </input>
       <output>
       <soap:body namespace='http://endpoints/' use='literal'/>
       </output>
       </operation>
       </binding>
       <service name='Commands'>
       <port binding='tns:CommandsBinding' name='CommandsPort'>
       <soap:address location='REPLACE_WITH_ACTUAL_URL'/>
       </port>
       </service>
      </definitions>


      Even if I replace the String_1 occurences by arg0 I get the error above. I don't know what to do, could anyone help me please??? Why does JBoss use this values instead of the WSDL values?!

      Thanks...

          Oh, I don't know if this could help, but I'm using EJB3 Stateless Session Beans exposed as services and I set everything with annotations (instead of using deployment descriptors, webservices.xml, etc). At least this used to run with 4.0.5.

            Phew! So sorry... but I solved the problem!!! The replacement wasn't functioning because, for some reason, I had to shutdown JBoss AS! When I runned the server again, the arg0 was found...

            Well... but it's so strange, do I really need to replace everything?!? I'll do this, but if anyone knows how to use the names generated by wstools, please tell me! ^^
