L2J Server

I am a beginner in L2J Server and in Java.
I would like to know where can I find the Enchant System? (for items not skills)
Or, at least, if someone could tell how it works.

Thx.

What do you mean? The core support for enchant scrolls?

Example:
I am in game, i will enchant an weapon. What will say if the weapon will be enchanted or not?

What/Where is the file that has the enchant system ?

network/clientpackets/RequestEnchantItem.java
and some more in AbstractEnchantPacket.java
