Could you try with disabling request compression : config.setGzipRequesting(false);
Did you use direct HTTP connection or did you got thru mod_jk for exampe ? Also I see you're using XmlRpcLiteHttpTransportFactory which is HTTP 1.0 and gzip support is only on HTTP 1.1. Could you try with XmlRpcCommonsTransportFactory instead ? 2006/4/12, Jochen Wiedmann (JIRA) <xmlrpc-dev@ws.apache.org>: > [ > http://issues.apache.org/jira/browse/XMLRPC-79?page=comments#action_12374161 ] > > Jochen Wiedmann commented on XMLRPC-79: > --------------------------------------- > > > Sorry, I forgot to mention that I updated the web.xml file accordingly so > > that the > > user-defined subclass is properly registered within the web application > > So it was wise not to close the issue. ;-) > > For now, I can simply confirm that I can reproduce the problem.
