can anyone tell me why im getting this error or what the textfile for play.bat should say, many thx

did u compile?
and u need jdk
here is link for jdk: http://lmgtfy.com/?q=jdk+download
and to compile just double click compile instead of play

also next time use the rsbot forums: http://lmgtfy.com/?q=rsbot

We have a RSBot section for a reason.
And the problem here isn't directly compiling, he have to set his path. Do THIS, and make sure you do everything. You also have to compile.
Note: The link is only a leeched guide of Karl's guide, but since RSBot's website is down at the moment, I'm posting link for that.
