    Receiving Compressed WebService Requests

      Hi,

      I have built a simple JAX-WS WebService (on JBoss 4.2.3.GA) which is supposed to receive a rather large data structure from clients. In order to speed up the transmission I would like the clients of my service to use http compressed requests.

      I have tried using SoapUI to test the service. As long as I turn off request compression in SoapUI everything works fine. When I set Request compression to "GZIP" or "DEFLATE" I get the following error from JBoss:

      14:35:33,042 ERROR [SOAPFaultHelperJAXWS] SOAP request exception

      It appears that the request is not uncompressed before it is forwarded to the SAX Parser. I am wondering how I can tell JBoss to run compressed requests through gzip before passing them to the SAX Parser? Or is it possible to write a custom HttpConnectionHandler in order to perform request decompression? I would be most thankful for any pointers you can give me. TIA :)
