Upgrading Rampage.

I went on an upgrading rampage yesterday and ended the day with the worst feeling. My Struts 1.1b2 application appeared to work fine on most things, however, I kept getting the following error when I tried to submit a form with indexed input values:

 	at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
 	at sun.reflect.NativeMethodAccessorImpl.invoke(

 	at com.onpoint.webapp.form.QuestionForm.getAnswer(

The items I attempted to upgrade were:

After hours of banging my head against the wall for hours and even trying versions of my code from a week ago, I decided to try the "classic" compiler in Ant. Which I soon learned should now be named "modern." Whalla - it fixed the above problem! My advice - DON'T USE JIKES 1.16 to compile your Struts-based web app! I also found that switching to modern from jikes reduced my build process from 1 min 20 seconds to 50 seconds - I'm sold. my face after fixing this bug

I ended up not upgrading to Tomcat 4.1.12 (rather to 4.0.5) because I found that my error-pages were not being recognized. I hope that a client using the application never sees an error page, but if they do - I'd rather them see my pretty page vs. a stacktrace.
