Do you have the right libraries open, like apcslib, or java.util.*?

[BetaWar]

Why don't you post the code so we can take a look at it?

[BigAnt]

What do you type in when you try to run the program?

[Ostralis]

Yeah seriously, we need to see some program to understand your problem, thanks!

[pbl]

The syntax is:

d> javac MyClass.java

To run the program you must type:
java programname

This is assuming that you are in the directory containing the compiled bytecode and that the class path is appropriately set, which it should be if it compiles like you said.


Also if you are trying to run the program you gave,which is an applet and cannot be run the way I just said, it must be used in a seperate html file.
