When trying to run xwork/ww2 app with Orion Server 2.0.1, I'm getting the following Exception:

I thought maybe my App is doing something wrong, and went to try webwork-example. Seemed to work ok, but after more carefull trying, I discovered the following behaviour:
If you first request some .jsp page, and only after some action with velocity result it works. But if just right after starting the server, I try to access some velocity result action, it breaks with the same Exception as above.
I hadn't this problem in Jetty, so I presume Orion is leaving some kind of jsp initialization to the moment when first jsp is requested, and this apparently screws velocity result, because it depends on JspFactory being initialized. Any clues how to resolve this?
