I made a jar file from Eclipse on Linux, but when I try to run the jar
I get the following error :

Exception in thread "main" java.lang.NoClassDefFoundError:

When starting the jar file with java in Linux, does the main class have
to have the same name as the jar file?

Solved it. The package name wasn't included before the class name in
the shell script when trying to run the main class in the jar.

This is a nightmare. I have documented many causes for it. I wish Sun
would do something to split this exception up so that the subspecies
gave you more clues. I have been juggling the causes over the years
trying to percolate the most common ones to the top.
