My computer used to run java files fine until i installed visual studio 2005. now it compiles the file but when i try to run the file it says:
Exception in thread "main"java.lang.NoClassDefFoundError:
I think it has changed all my java files into J# files or something. Can anyone help me fix the problem so i can run my java files as before?

:
check your classpath. Sometimes you get errors if the path is anywhere but the front of the path string.
