Web Service SOAP server was unable to process request

Hi I'm develping a web app in Java for a local bank and they have a SOAP Web Service that my app consumes. The app is deployed on GlassFish 3.1.2 and the web service was generated on .Net (I don't know the specifics, I'm new to the project) and everything is connected through a peer to peer VPN.

Now the issue I have is when I try to log in I get an EJBException:

javax.faces.el.EvaluationException: javax.ejb.EJBException Caused by: com.sun.xml.ws.fault.ServerSOAPFaultException: Client received SOAP Fault from server: Server was unable to process request. ---> Changes to this object and its sub-objects have been disabled (Exception from HRESULT: 0x8011042A) Please see the server log to find more detail regarding exact cause of the failure.

Now I'm trying to determine what exactly is the problem with the web service, or even better what should the guys at the bank check to determine what's wrong.

If anyone knows or has some ideas on what we should check please let me know. Thanks

Seems to be server problem. Send them exactly time stamp of request and all the request details, and they will probably guide you to the problem
