Oracle 10g migration problem

I'm trying to migrate a struts-based webapp from Tomcat 4.1.18 to Oracle 10g.  The webapp uses XSLT and FOP.  I got the following error:

500 Internal Server Error

java.lang.NullPointerException

Any ideas what and why this is happening?

I had to downgrade from struts 1.2.7 to struts 1.1 to get this far.  Otherwise, I'd stumble on:

javax.servlet.UnavailableException
      at org.apache.struts.action.ActionServlet.init(ActionServlet.java:368)

and wouldn't even get to the Digester.
