    Raw Style webservices [Design question]

    Vinicius Carvalho Apprentice

      Hello there! I'm developing a Topdown webservice, and defining my own WSDL, and using @WebserviceProvider annotations.
      The service is running, I can access it using webservice explorer or SOAPUI. When I generate the client using JBoss WS, I'm getting some errors on the response. I know it's something related to my WSDL, and SOAP response. So I was hopping someone could assist me:

      WSDL

      public class CommandProcessor implements Provider<Source> {
       Source returnMessage;
       public Source invoke(Source messge) {
      
       DOMSource domSource = null;
      
       try {
       Transformer transformer = TransformerFactory.newInstance().newTransformer();
       transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
       transformer.setOutputProperty(OutputKeys.METHOD, "xml");
       OutputStream out = new ByteArrayOutputStream();
       StreamResult streamResult = new StreamResult();
       streamResult.setOutputStream(out);
       transformer.transform(messge, streamResult);
       String xmlReq = streamResult.getOutputStream().toString();
       System.out.println(xmlReq);
       domSource = new DOMSource(createResponseContent());
       transformer.transform(domSource, streamResult);
       xmlReq = streamResult.getOutputStream().toString();
       System.out.println(xmlReq);
       } catch (Exception e) {
       // TODO Auto-generated catch block
       e.printStackTrace();
       }
       return domSource;
       }
      
       private Document createResponseContent() throws Exception{
       DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
       dbf.setNamespaceAware(true);
       DocumentBuilder db = dbf.newDocumentBuilder();
       Document doc = db.newDocument();
       Element responseCommand = doc.createElementNS("http://www.acme.com/sys/definitions", "sys:CommandResponse");
       Element ret = doc.createElement("return");
       Element id = doc.createElement("id");
       id.appendChild(doc.createTextNode("1"));
       Element message = doc.createElement("message");

       ret.appendChild(id);

      Well, first, when I run ws-provide it throws a lot of warnings on the console, but it seems that all artifacts are created (Port,Service,Bindings,ObjectFactory).

      Ok, running using soap ui:

      Request:
      
      <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:sys="http://www.acme.com/schemas/sys">
       <soapenv:Header/>
       <soapenv:Body>
       <csm:anyCommand>
       <asteriskCommand>
       <voip>true</voip>
       </asteriskCommand>
       </csm:anyCommand>
       </soapenv:Body>
      </soapenv:Envelope>
      
      Response:
      
       <env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">
       <env:Header/>
       <env:Body>
       <sys:CommandResponse xmlns:sys="null">
       <return>
       <id>1</id>
       <message>comando recebido</message>
       </return>
       </csm:CommandResponse>
       </env:Body>
      </env:Envelope>
      


      Now, the odd thing, is that the xmlns:sys is null, when I print it on the serverside it displays that the xmlns:sys is pointing to the namespace.

      So I run this test with the generated client proxy, and I get an error:

      Caused by: org.jboss.ws.WSException: Cannot find child element: {http://www.acme.com/schemas/sys}CommandResponse

      I really don't know if this is caused because the xmlns is being returned null, and if so, why? Or did I messed the whole doc/literal wrapped/bare style? I was thinking that I was using bare style :)

      Any help would be great :)
