--------------------------------------------------

                 Key: CXF-2537
                 URL: https://issues.apache.org/jira/browse/CXF-2537
             Project: CXF
          Issue Type: Improvement
          Components: Transports
    Affects Versions: 2.2.3
            Reporter: Cyrille Le Clerc


Troubleshooting of client side HTTP exceptions is often difficult for 
development, integration and troubleshooting teams.

Here is a proposal of enhancements of the exception messages :
* Add the HTTP error code for 404 exceptions in addition to the message 
returned by the server.
** Current message : {{java.io.IOException: Not Found}}
** Enhanced Message : {{java.io.IOException: HTTP response '404: Not Found'}}
* Add intermediate IOException with the invoked URL in the stack of causes of 
the "WebServiceException: Could not send Message." exception.
