From error to error. - Endpoint invocation resulted in exception

[salva]

The web service is invoked, an return an ELEMENT type, the I have a SOAP Exception. I'm using the new Snapshot version.

2006-07-06 11:28:44,129 INFO  [STDOUT] 2006-07-06 11:28:44,129 INFO [xxx.controlservidores.ws.ReceptorFtpEndPoint] - Devolvemos como resultado OK

This is the EndPoint code. I introduce a try--catch just before the return code... as you can see the Exception goes after the return code...

protected Element invokeInternal(Element requestElement, Document document) throws Exception {
		logger.info("invokeInternal. " + requestElement.getNamespaceURI() + " - " + requestElement.getLocalName());
		Assert.isTrue(NAMESPACE_URI.equals(requestElement.getNamespaceURI()), "Invalid namespace");
        Assert.isTrue(ECHO_REQUEST_LOCAL_NAME.equals(requestElement.getLocalName()), "Invalid local name");

        NodeList children = requestElement.getChildNodes();
        Text requestText = null;
        for (int i = 0; i < children.getLength(); i++) {
            if (children.item(i).getNodeType() == Node.TEXT_NODE) {
                requestText = (Text) children.item(i);
                break;
            }
        }
        if (requestText == null) {
            throw new IllegalArgumentException("Could not find request text node");
        }
        try {
        String servidor = requestText.getNodeValue();

        logger.info("Se invocó el servicio con valor " + servidor);
        String resultado = receptorFtpService.setAlive(servidor);
                
        Element responseElement = document.createElementNS(NAMESPACE_URI, ECHO_RESPONSE_LOCAL_NAME);
        Text responseText = document.createTextNode(resultado);
        responseElement.appendChild(responseText);
        logger.info("Devolvemos como resultado " + resultado);
        return responseElement;
        }
        catch (Exception e) {
        	logger.fatal(e.getMessage());
        	return null;
        }

Thanks in advance...

It's just a hunch, but are you using JBoss by any chance?

[salva]

Yes, I'm using JBoss 4.0.3SP1 and 4.0.4GA.

[Arjen Poutsma]

Yeah, that's what I thought. I think it's a bug in JBoss's implementation of SAAJ. I've notified the JBoss developers: http://www.jboss.com/index.html?modu...wtopic&t=86580, so let's hope it gets fixed soon.

As a workaround, you can override JBoss's SAAJ implementation with the reference implementation. I'm not a JBoss expert, so I don't know how this is done, but I think you can find resources on the web that tell you how.

Thank you very much...
