L2J Server

[Help] What is structure of L2J Project?
Because in one file .java of com.l2jserver.***, you import many class, so I dont know what is the basic class which dont import any class of com.l2jserver.***.

Try to do like I do: find some function that uses the same class and look how it's works to "copy" the code functionalityes.

I use it and it's working 'till now.

There are many kind of entities in l2jserver, which has their base class. Depend on what you are looking for, theres a class or another. But there is no a "Object" class from which everything inherits (theres L2Object, base class just for game entities, like players, npcs or items)

This image could illustrate it a bit more:
