Hi, i'm using XPathPayloadEndpointMapping to route POX messages to specific endpoints. If the request contains invalid xml i currently get a

Code:

I'd like to be able to handle this in a more elegant manner. I've looked at using a custom interceptor, but the documentation states that the interceptor...

"Processes the incoming request message. Called after EndpointMapping determined an appropriate endpoint object, but before EndpointAdapter invokes the endpoint. "

... which would be too late in the chain since XPathPayloadEndpointMapping would have already tried to run an xpath query on the incoming request.

I also thought about using an ExceptionResolver, but the supplied classes only seem to support SOAP (as opposed to POX).

Any ideas about this?

Thanks.
