I am trying to upgrade from Tomcat 3 to 4 on our AS400. I downloaded the latest version, extracted it to the IFS, did the recommended optimization, and used the startup and shutdown scripts I found on iSeries Network. It started like a charm.

The problem is, I can view html pages and servlets, but when I try to view a jsp I get an error. I think the error can be traced to this part:

. ...

Mainly the "com/ibm/as400/system/OS400Process", has anybody experienced this problem before or anything like this? I can include the complete log if anybody needs to see more. I think this is something I am missing on the 400 but I have no idea where to start.
