Class loading from other jars

So I am working on this weapons plugin and making it so that weapons can be added by putting jarfiles in a certain folder but I can't seem to get the classloading to work. This is the code that I have now:

the loading method

the Weapons class

The console showed the following when trying to load a jar with just this class:

Code:

Sgt_Tailor Ive had issues with: if(c.getSuperclass() == Weapon.class){, use this instead:
if(Weapon.class.isAssignableFrom(c)){

The superclass of c will return Object unless c implements Weapon and doesnt extend it.

 

Chiller but the problem lies here: Class c = cl.loadClass(className);
