Customizing Checkstyle for our projects

Hey Guys,

I'm trying to customizing some checkstyle rules, but i'm having some troubles... The Java implementation of the rules seems to be easy...
But when I try to follow the tutorial instructions from the Checkstyle website, it simply doesn't work ! I just can't integrate my own rule in a
standard set. I do all the stuff, I edit the xml ruleset file, I create a jar file, but maybe I forgetting something... does anyone here have some experience with checkstyle
and could share it with me ?

I sure that I can't say "I tried everything"... but all my possibilities is over... i dont know what to do anymore... !

I can be more specific if it needed

Thanks
