Re: NoClassDefFoundError after upgrade to FC3

Thanks for the reply. That's the whole error as far as jdev is concerned. When I try to run eclipse I get the following error, which may or may not be related:

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

Also, I just upgraded my java rpm (and set JAVA_HOME to the new location), so I know all the files are there. It must be a jar file that isn't in the classpath. What jar files would normally be in the CLASSPATH?

Are you giving us the entire exception message?  It should tell you which
class it is looking for.  I think it usually prints right before the stack
trace.

A NoClassDefFoundError means either a .jar file is missing or your CLASSPATH
enviornment no longer contains the necessary file.

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?

Hi everybody. I use jDeveloper from Oracle to program, create GUIs and manage my various projects. It's not open-source, but it's a very good program. I have been using it without errors for at least a year.
Then, when I upgraded to Fedora Core 3, it was the only thing on my computer that stopped working. When I click on the icon on my desktop, nothing pops up, and top shows a massive load on the CPU for "jdev".
When I run it in a terminal window, I get the following error:

java.lang.NoClassDefFoundError

      at oracle.jdeveloper.JDeveloper.launch(JDeveloper.java:58)
      at oracle.jdeveloper.JDeveloper.main(JDeveloper.java:37)

I've got the same java SDK I had before, and the configuration files are pointing to it. Can anybody think of why an upgrade to Fedora Core
3 would be causing this error?

Thanks,
Cyrus
