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?
