Debugging drl files

Issue

• How to debug rules which are written in drl files in JBDS ?
• Is it possible to have breakpoints in a drl file which is being used in a web application ? There is a situation where a web application uses Drools and it loads all the rules from a .drl file. Users would like to have a breakpoint set in the drl file to check the variables within it. Is there a way to do it?
• How can we debug the rules while it is running on BRMS?
