How to Fix the NoClassDefFoundError.

Ok, I've seen a lot of threads asking this question lately, so I decided to make a thread to answer it! Perhaps a mod could sticky this?

Sometimes when you try to run a bot or other Java program, you might receive this error:

Code:

Exception in thread 'main': NoClassDefFoundError: [classfile]

This means that java.exe couldn't find the classfile you specified.

This could be fixed several ways, one of which Sythe described in another thread. I'll repeat that here:

Instead of typing:

Code:

java [myclass]

type

Code:

java -cp . [myclass]

Another way Sythe described was to do this:

Right click My Computer and select properties (or hit windows + break).
Click on the Advanced tab.
Click on the Environment Variables button.
Find the variable called 'path' and add this onto the end of it:

Code:

.;

This should fix your problem.

If you have any other problems, post 'em here!
