Hi,

I'm using J2SDK1.4.0_02, and I've create a Java program. During the compilation there is no error occurred. After compiled, I tried to run the program, I got the error shows below:
"Exception in thread "main" java.lang.NoClassDefFoundError: Simple"

The word "Simple" is the class name. I've tried to create another Java program, the same error occurred.

Can someone help me to solve this problem.
Thanks a lot.
