Shame on you, if you does something, make it properly or do not do it at all :P
@Andrey
If you would be a lil bit smart, you would open ANY file and use SEARCH for L2DatabaseFactory and see how that Connection con should looks like, is that so hard to TRY to manage it on your own - no offense, it's just the way you should follow.. Searching for ready codes / examples to fix your error..
Connection con = L2DatabaseFactory.getConnection()
should be
Connection con = L2DatabaseFactory.getInstance().getConnection()
