JVM is not able to find out class for that source file, first check where the class was made when the source was compiled and check the classpath also while running the program, When the program runs it should look into the path where the class was made while compiling.

Thanks and Regards,

can you post the FULL text of the error message? it should tell you WHAT class it can't find. This is probably a classpath issue, but how to resolve it may depend on what class you can't find, where it is, and where you are running java from...

There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors

Have a look at PATH and CLASSPATH
