    NullPointerException with a WS request

    Sandeep Mohan Newbie

      I am using Jboss-4.0.5 and JbossWS-1.2.1. I get this error, and it occurs now and then. 80% of the time it works and 20% of the time it throws the following error.

      The Client side is registering the SOAP request which was sent down to the server, and everything looks OK. Is there any known issue regarding this?
