Description

Our product relies on the feature that AxisServer can return WSDL document which we can process. Basically we do like below:

AxisServer engine.generateWSDL(msgContext);
Document wsdlDoc = (Document) msgContext.getProperty("WSDL");

And, the wsdlDoc is the org.w3c.dom.Document type which is what we want. And we have a simple class which processes the wsdl document like below:

public class WSDLUtils {
private static WSDLReader _wsdlReader = null;

public WSDLUtils()
throws WSDLException {
if (_wsdlReader == null)

{ WSDLFactory factory = WSDLFactory.newInstance(); _wsdlReader = factory.newWSDLReader(); }

}

public WSDLReader getWSDLReader()

{ return _wsdlReader; }

public Definition getWSDLDefinition(Document wsdlDoc)
throws WSDLException

{ WSDLReader reader = getWSDLReader(); return reader.readWSDL(null, wsdlDoc); }

}

And everytime we run this, we get the exception like this:

So I decided to test on axis itself and after modified org.apache.axis.transport.http.QSWSDLHandler#invoke() method add lines like below (line 74)

try

{ //beginning of test WSDLFactory wsdlFactory = WSDLFactory.newInstance(); WSDLReader wsdlReader = wsdlFactory.newWSDLReader(); wsdlReader.setFeature("javax.wsdl.verbose", true); Definition definition = wsdlReader.readWSDL(null, wsdlDoc); System.out.println("definition = " + definition); //end of test }

catch (Exception e)

{ e.printStackTrace(); }

And compile axis and test http://localhost:8080/axis/services/AdminService?wsdl to invoke the method above, and I saw exactly the same exception in the console, which means that the wsdl document object returned by AxisServer.generateWSDL() can not be processed by WSDL4J API.

Couple of others:
1. the tests failed in 1.2 beta2 and 1.2GA, so it should not be a problem of WSDL4J
2. http://localhost:8080/axis/services/Version?wsdl works okay in beta and GA
3. I wrote test case like below:

public static Definition testA() {
Definition definition = null;
try

{ String filename = "d:/dl/UojDocumentService.xml"; DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); /*note*/ dbf.setNamespaceAware(true); DocumentBuilder db = dbf.newDocumentBuilder(); FileInputStream fis = new FileInputStream(new File(filename)); InputSource inp = new InputSource(fis); Document doc = db.parse(inp); System.out.println("doc = " + doc); WSDLFactory wsdlFactory = WSDLFactory.newInstance(); WSDLReader wsdlReader = wsdlFactory.newWSDLReader(); definition = wsdlReader.readWSDL(null, doc); System.out.println("definition = " + definition); }

catch (Exception e)

{ e.printStackTrace(); }

return definition;
}

After saving the wsdl as the xml file on disk, the code above runs okay. But if I didn't run /note/ dbf.setNamespaceAware(true); I get similar exception as above.

3. running WSDL4J process the wsdl online runs okay so the problem has to be in the docuemnt object rather than the xml document.
