[jira] Updated: (AXIS-2132) WSDL document object generated by AxisServer can not be read successfully using WSDL4J API
[ http://issues.apache.org/jira/browse/AXIS-2132?page=all ]
xiao-fei song updated AXIS-2132:
--------------------------------
Attachment: QSWSDLHandler.java
> WSDL document object generated by AxisServer can not be read successfully using WSDL4J API
> ------------------------------------------------------------------------------------------
>
> Key: AXIS-2132
> URL: http://issues.apache.org/jira/browse/AXIS-2132
> Project: Apache Axis
> Type: Bug
> Components: WSDL processing
> Versions: 1.2 Beta, 1.2RC1, 1.2RC2, 1.2RC3, 1.2
> Environment: Testing on windows 2000, tomcat 5.0.28 and 5.5.4, apache axis beta 2 and 1.2 GA
> Reporter: xiao-fei song
> Priority: Critical
> Attachments: QSWSDLHandler.java, UojDocumentService.xml
>
> 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:
> July21 11:42:45 2005: [Thread-18] java.lang.IllegalArgumentException: local part cannot be "null" when creating a QName

> 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.
