Tomcat/Spring woes

Hi Ho java400 peeps,

I joined this list a couple of weeks ago mostly as an audit, and here i am already with an odd problem.
I am running java 1.4.2_16 and tomcat 5.5.1 on our iSeries. I have a webapp that was straight javax.servlets (java emitting html) and it's been running fine for a couple of years.
Recently i needed to add a feature and rather do more yucky brute forcing, i reworked the app to be spring/jsp/mvc based.
This has been a disaster. java.lang.StringBuilder not found? At this point, thousands of java.lang classes have been loaded, and several jsp pages have been displayed.

This is my first Spring on iSeries foray. I have done lots of Spring on Windows/Linux. In fact, this war file runs flawlessly on those two platforms.

Has anyone else had a similar problem? Missing basic classes? Any Spring successes? (i would imagine so).

Thanks in advance for any insight available.
