Hey was trying to run the class file from cmd after a long years and had stuck with this beginners time error. But suggestion of including classpath of the .class file using set classpath = and then running java command worked really well.

Thanks a ton !!!

Thanks so very much for this simple and clear solution.i had set all variables and did a lot of copying from one directory to another but to no avail until i issued this simple command and it ran perfectly.
God bless you!
Thanks again

omg i have been working on this FOREVER and none of the many suggestions worked. But first i should tell you that every single step I had huge problems but I never gave up because I have successfully configured a few years ago when I first tried to teach myself Java. Anyway, I have made many mistakes configuing the CLASSPATH so I really didn’t know what to fix. After finally getting it to compile successfully (creating the class file) it still wouldn’t work. Finally I tried this…and I didn’t see it anywhere in this blog so I hope it helps everyone after me. In addition to what you have in the CLASSPATH (int the envir. varables)add the following without deleting anything you already have there:

.;C:J24work

instead of J24work you should enter the exact path to where you are puting you .java and .class files which is probably different from where you JDK is for some people.

I truly hope I explained this well and it helps someone.
