Problems running Java Application. Prease Help Me!!

Question

I've just finished a java application to my University, I used Forte for Java and the Timer that comes with it, it works fine, but, when I try to run it from outside Forte, it's just impossible, I even create a .jar file(with Forte 4), but when I try to run it from Forte, it tells me this:
java.lang.NoClassDefFoundError: org/netbeans/examples/lib/timerbean/TimerListener
Exception in thread "main"
it seems that it's a problem with the Timer, why??
And when I try to run it from the explorer (Windows), by double clicking the file, it tells me:
Java Virtual Machine Launcher
Could not find the main class. Program will exit!
But how is that possible??, it works fine with Forte. That's my problem, I need to take it to the teacher, but I can only run it from Forte now. What can I do??? Any suggestions?. I Hope that somebody can help me, please.

This sounds like a problem with the classpath. I was facing similar error with another application. Finally I ended up unzipping the class files and putting them in a directory that was in my class path.
Or you could explicitly specily your classpath.
Say your application (called app) is in c:\java\app and your classes are located in c:\java\classes\ where classes is directory run it like:
c:\java>java -cp c:\java\classes[;second path] app
hopefully it works.
