NoClassDefFoundError after upgrade to FC3

[Cyrus Adkisson]

Well, I uncovered one big clue. Whenever you upgrade to FC3, the system 
attempts to install gcc-java (and does) which can screw up the workings 
of your Sun java considerably. Among other things, FC3 installs a 
/usr/bin/java script that points to the gcc-java code so when you type 
java -version it gives you a bunch of gcc output. If you disable the 
/usr/bin/java script, then it will revert back to the Sun java.

However, doing that did not fix my problem. Jdeveloper still gives the 
same error I posted previously, as if it's searching for something in 
the classpath. Eclipse does something similar. Can anyone help me 
understand what I might need in the classpath for this to work again?
