Rather urgent: RUNNING JAVA APPLICATIONS

How would I run a Java application I have made?

I suppose you are looking for more than:
java YourClass
or
javaw YourClass

So you might want to check out the deployment post

Well, I'm one of those who have taken Java in school, loved it and tried to take the development home. Well, I got the developer kit with the compiler and all that, and actually can compile java applets as well as applications. I have only written applications in school so far, and home I've only made a couple of applets. With them, you just need a browser to run them, but with applications you have to run them, they are stand alone. In school, I can just type "javac myProg.java" and then "java myProg". That's it. But home, it compiles, but when I try to do the "java" command, it gives me

Exception in thread "main" java.lang.NoClassDefFoundError: e:\java\game\game

Where the class would be in e:\java\game\game.class

Thank you so much for any help you could give me (I'm toast if I can't figure this out by Tuesday, it's for school and due then).

Could I see the game source?

Code:

I took out some of the code, just some insignificant functions... this should be all you need to look it through. It compiles OK, there's just something wrong with running a java application...

What class was it complaining that it couldn't find? You probably have to set the CLASSPATH to point to your custom classes. You set it like the regular DOS PATH. There are posts here on that too. Good luck.
