yea after setting up, I realized a lot of things were missing. I started to try to download all the programs which could help. one of which is NetBean IDE. so, to make my server even better, I started using NetBean IDE to do some scripting in the source files.
I managed to add passive haste, new commands that works and also maybe some shops. well, doing these has already cost lots of time and really I wondering if it is worth it. java programming feels just like c++ with a little more complicated stuffs. everything merely copy and paste but still there's some knowledge needed.
