Hi all,

Let me carry on this thread, I am running into the same problem and one thing I am pretty sure is that there is no proxy in the way.

Following is the stacktrace:

Note:
report generation worked okay when icescrum ran in tomcat 7, but I downgrade tomcat 6 since I found tomcat 7 sometimes hangs there for no reason and eventually it will need to be restarted.

Hope this gives you a clear hint.

Thanks
Ben
