Hi people.
I saw that in Axis 1.3 is possible to enable SOAP compression. Following Simon Fell example (http://www.pocketsoap.com/weblog/2005/10/1565.html) I put the next lines on my client code:
call = (Call) axisService.createCall();
call.setTargetEndpointAddress(endpoint);
call.setMaintainSession(true);
*** call.setProperty(HTTPConstants.MC_ACCEPT_GZIP, Boolean.TRUE);***
*** call.setProperty(HTTPConstants.MC_GZIP_REQUEST, Boolean.TRUE);***
call.setOperationName( "createUser");
call.addParameter( "ticket", XMLType.XSD_ANY, ParameterMode.IN );
call.addParameter( "userProperties", XMLType.XSD_ANY, ParameterMode.IN );
call.setReturnType( XMLType.XSD_ANY );
return (User)call.invoke(new Object [] {ticket,userProperties});
I also added the CommonsHTTP client as suggested on the blog entry.
Then I executed a remote web service call and I used tcpmon to see the
results. The request is successfully encrypted, but then an exception
is thrown at the server:
Caused by: org.xml.sax.SAXParseException: Content is not allowed in prolog.

Note that this exception does not happens if I use the traditional HTTPTransport and disable CommonsHTTPSender transport
Thanks for your help!
