What is the reason for this exception?

We use the RQM Version 2.0.1.1 iFix1 and Jazz Server 1.0.0.2 iFix 5.
The apache server runs in a different server environment as the tomcat for RQM.
Apache is running in AGV network and RQM Tomcat is running in MVDI Network. The communication between both server running over port 22 (SSH tunneled) and with AJP protocol. OS is Unix on both server.

Thx and Regards
Magnus
