> Key: SCOUT-105
> URL: https://issues.apache.org/jira/browse/SCOUT-105
> Project: Scout
> Issue Type: Bug
> Components: Scout Implementation
> Affects Versions: 1.2.2
> Reporter: subes
> Assignee: Kurt T Stam
> Fix For: 1.2.3
>
>
> I am using org.apache.ws.scout.transport.LocalTransport with juddi-client
> 3.0.4. I had several exceptions in it because of wrong dependencies and
> inproper configuration. To resolve all these issues I had to manually debug
> the Scout code because the stacktraces of juddi-client are being eaten by
> LocalTransport.
> This is the problematic method:
> public Element send(Element request,URI endpointURI)
> throws TransportException
> {
> Element response = null;
> if (log.isDebugEnabled()) {
> log.debug("\nRequest message:\n" +
> XMLUtils.convertNodeToXMLString(request));
> log.debug("Calling " + endpointURI + " locally");
> }
> try {
> String className = endpointURI.getPath();
> String methodName = endpointURI.getFragment();
> log.debug("Calling class=" + className);
> log.debug("Method=" + methodName);
> Class<?> c = Class.forName(className);
> Object requestHandler = c.newInstance();
> Method method = c.getMethod(methodName, Element.class);
> Node node = (Node) method.invoke(requestHandler, request);
> response = (Element) node.getFirstChild();
> } catch (InvocationTargetException ite) {
> throw new TransportException(new
> Exception(ite.getTargetException().getMessage()));
> } catch (Exception ex) {
> throw new TransportException(ex);
> }
> if (log.isDebugEnabled()) {
> log.debug("\nResponse message:\n" +
> XMLUtils.convertNodeToXMLString(response));
> }
> return response;
> }
> Because this part removes the stacktrace:
> ...
> } catch (InvocationTargetException ite) {
> throw new TransportException(new
> Exception(ite.getTargetException().getMessage()));
> }...
> I had to add a watch expression for
> ite.getTargetException().printStackTrace() to debug my issues. Finding this
> workaround and having to do this on my trial and error work caused quite a
> slow down in my progress.
> It would be better if you just removed that code part and let the follow-up
> catch-clause handle the errors:
> } catch (Exception ex) {
> throw new TransportException(ex);
> }
> Also, why do you wrap the Message in an Exception which is then wrapped by
> TransportException? This was quite confusing for me initially and in my
> opinion senseless.
