Not quite sure what you mean by "full command"? You using eclipse IDE right?

The engine isn't open sourced and from what I've read, it won't be until EgonOlsen has had enough of JPCT.

You have to add -classpath <yourpath>/jpct.jar;<yourotherpath>lwjgl.jar or similar, i.e. you have to include at least the jpct.jar (and the lwjgl.jar as well if you are using parts of it) to the classpath of your javac call.

No. And i don't see the point of it...this isn't related to any API. It's just about how to use Java on the command line. Any tutorial that explains this will do...in your case, it can't find the class because it's not in your classpath. Just add the directory that contains your class file/package to the classpath.

Egon is right, this is not a problem related to jPCT.
Let's see if I understand: you can compile it, but can't execute it, right?
Are you sure the main class is in the right directory? Your command line seems to be ok, so you shoud check your file structure.
