I don’t know much about how to use it, but to install it as an eclipse plugin, this should work:
- Start Eclipse
- Help -> Install New Software
- In the Work With: or Site: input field, enter: “**http://download.jboss.org/drools/release/`<VERSION
>.Final/org.drools.updatesite/**", replace "`” with appropriate version and click the “Add” button - For the Name you can just enter “Drools”
- Check the Drools and jBPM checkbox and follow the instructions to get it installed.
Master the Boss http://www.mastertheboss.com/ has some tutorials on how to use it as well
The Drools downloads page is at: http://www.jboss.org/drools/downloads
