Understood, but they want to know why it works fine on one box and I have the other issues on the other box. I noticed that the box in question had no pointers to the lib directory.... Neither did the box that works correctly. So does tomcat generate it's own set of classpaths at start up? If so where is that configuration contained? The only difference in the boxes is one has oracle thrown in the mix which does have it's own class paths for java.
