[jboss-user] [JBossWS] - Raw Style webservices [Design question]

[viniciuscarvalho]

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:

My Provider


  | 
  | @Local
  | @Stateless
  | @WebServiceProvider(wsdlLocation="META-INF/wsdl/CommandProcessor.wsdl",
  | 					targetNamespace="http://www.acme.com/sys/definitions",
  | 					serviceName="CommandProcessorService",
  | 					portName="CommandProcessorPort")
  | @ServiceMode(value=Service.Mode.PAYLOAD)
  | 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");
  | 		message.appendChild(doc.createTextNode("comando recebido"));
  | 		ret.appendChild(id);
  | 		ret.appendChild(message);
  | 		responseCommand.appendChild(ret);
  | 		doc.appendChild(responseCommand);
  | 		return doc;
  | 	}
  | 
  | }
  | 

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 :)

Regards
