Please help what have i done wrong.

Error on: /home/l2v/l2vb/game/data/scripts/custom/555_NPCBUFFER/__init__.py.error.log
Line: -1 - Column: -1

Traceback (innermost last):
File "custom/555_NPCBUFFER/__init__.py", line 7, in ?
ImportError: no module named jython

Is this a custom buffer you are using?
Maybe it's not compatible with l2j?

I managed to fix it, needed some code changes.
