NoClassDefFoundError after upgrade to FC3

I disabled the gcc-java a long time ago. "java -version" and "which
java" show that the system is using my Sun JDK. I also went back and got
the recommended version of Sun JDK (1.4.2_03) and it does not fix the
problem. This is really frustrating. I can't get jdeveloper, eclipse or
netbeans to install. I'm going to need something to program with soon.
As far as eclipse, you may remember the error was:
java.lang.UnsatisfiedLinkError:
/usr/local/eclipse/plugins/org.eclipse.swt.gtk64_3.0.1/os/linux/amd64/libswt-pi-gtk-3063.so:
/usr/local/eclipse/plugins/org.eclipse.swt.gtk64_3.0.1/os/linux/amd64/libswt-pi-gtk-3063.so:
cannot open shared object file: No such file or directory
Yet, ldconfig -p shows the file linked properly and the directory is
listed in /etc/ld.so.conf. ldd on that file doesn't show any broken
links, either. I'm totally baffled.
