As you can see I specified the classpath and everything else.........what is the problem??!

Answer 1

well some things to check then.
- does said jar still exist at that precise location?
- do you have the rights to read that file as your current user?
- can you open the jar with a zip tool?
It might pay off to use a tool like ANT to build your code by the way, at least you'll only have to configure your classpath, source and destination folders once and then forget about it.
