i am using gwt1.5,struts2,spring and hibernate. and also using the NTLM filter for
for authentication..
we are using the NTLM to authenticate. When making the rpc calls we are using the filter for the first request and from the next request onwards we are by passing the filter.
This by passing is working well in firefox. BUT in case of IE it is requiring the authentication for every request . And it is throwing the following exception :-

<Error> <ServletContext-/PersonalePianoFerie> <vm11sv17> <serverDP1> <[ACTIVE] ExecuteThread: '8' for queue: 'weblogic.kernel.Default (self-tuning)'> <<anonymous>> <> <> <1257246017406> <000000> <Exception while dispatching incoming RPC call >
java.lang.IllegalArgumentException: encodedRequest cannot be empty
at com.googlcode.strut2gwtplugin.interceptor.GWTServlet.processCall(
at javax.servlet.http.HttpServlet.service(
