Angry peaved about java 1.4.2 and mozilla firebird (solved)

This whole issue has been caused by me wanting to use firebird on slack 9 with the java VM plugin.

I followed the instructions for downloading and installing the jre and simlinking the java plugin in the mozilla plugin directory.

I started firebird and when i typed about:plugins in the address bar it showed the java plugin installed. When I go to use it however, the browser crashed.

So, I narrowed it down to a problem with a my java install.

/usr/java/j2re1.4.2/bin/java -version
Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/Object

I have read some stuff about CLASSPATH, but i don't have a clue if that is a program variable or a bash variable and what it should be set to. Help would really be appreciated.

They have install instructions on their page which I followed (pretty easy).

Then I made the symlink for the plugin (explained on their page or at

Now everything works.
