SOAP Message Handler

Question

I have a WSDL URL that i used to create a web service client using wsimpot command
now i want to log all the in-going and the outgoing XML
so i think to user SOAP Handler but it did not works with this service
but it works with another service client . So my question here is this the right way to log the calls as i need to log all the parameters and log the response also or there is another way .

and why the handler did not work with this client but works with other clients ?

It depends on how you implemented your handlers - a normal way to achieve such functionality is just to add a handlerChain, similar to this:

bindingProvider.getBinding().setHandlerChain(CollectionUtils.toList(new Handler[]{new SimpleHandler()}));

Within the SimpleHandler (that obviously must implement: SOAPHandler<SOAPMessageContext>), you'll basically do something like this:

@Override
public boolean handleMessage(final SOAPMessageContext messageContext) {
    if (messageContext == null) {
        LOG.warning("The messageContext was nilled. Unable to handle the soapMessage.");
        return false;
    }
    if (Boolean.FALSE.equals(messageContext.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY))) {
        LOG.finest("Some cool incoming message");
    } else {
        LOG.finest("Some cool outgoing message");
    }
    return true;
}

The bindingProvider mentioned earlier, you'll snap from the initialization of the WebService itself. Most likely something like this:

final SomeCoolService someService = new SomeCoolService("my/path/to/service.wsdl", new QName(.., ..));
    coolServicePort = remedyService.getCoolServicePort();
    if (coolServicePort != null) {
        final BindingProvider bindingProvider = (BindingProvider) coolServicePort;

In your case, the handler you added didnt work - did it even get initialized during the init of the handler-chain?

The less obvious way to log these things, is by using other tools such as Wireshark, however I doubt that is suffient for you - unless you'll just want to trace whatever being sent back/forth.
