NullPointerException with Sandesha1

Hi,

I am testing our company’s web services intermediary (called Network Director) for the RM capability using

Sandesha’s sample implementation of RM client and RM provider. When I run the Sandesha’s AsyncPingClient

‘Against the Sandehsa’s RMSampleService (deployed on Tomcat), I see the correct http ok response when using TCPmon

Between client and the server. However, when using the Network Director in the middle, I get the an NPE from Sandesha.

I captured the message in the tcpmon that is being sent from Networkdirector to the Sandesha’s sample service and sent it using curl and

Got the same NPE (see attched message):

Am also attaching the message that works and if I change the sequence Identifier in the asyncTest.xml with the one in asyncTest_work.xml, the

asyncTest.xml message also works! I can’t explain why Sandesha is throwing NPE as it generated the CreateSequenceResponse correctly and the message being

sent is using the sequence ID returned by Sandesha. I think it is a bug in Sandesha. Have you seen anything like this before?

Also, the source and the binary version I am using don’t seem to match. How can I get the latest binary version that is not released yet that may have the fix for this problem?

Thanks very much for your reply! This problem is currently a road blocker for us.
