The thing is actually like this sir, i need a source code where i can use on my desktop and see it run on the desktop and actually just see the applet without having to create it into xml and jar and so on, just to see it run after the code is written in netbeans. The problem is the program has to import this [color=blue]org.colos.ejs.library._EjsConstants [/color] package which I don know where it is and then in the code there is this line [color=blue]static public String _getEjsModel() { return "./Collision2D_e.xml"; [/color] which if by using EJS would run but if just written in netbeans would not.
