JBossRules

Welcome to the wiki of page for JBoss Rules. Otherwise known as Drools 3. Please feel free to add your own tips/gotchas - you just need to signup for a jboss.com account (free and open to everyone). Currently the JBoss wiki is still on the jboss.com site so you will find the links for the naviation on the left may have change if you linked through from JBoss Labs, confusing I know. This will be resolved in next JBoss Portal release when JBoss Wiki will be properly integrated with Jboss Labs.

 

To clarify - Drools is the project development name, our R&D play pen. JBoss Rules is productized stable branch of Drools with additional support, consultancy and training; backports of bugs will be applied to JBoss Rules, but almost never to Drools.

 

NOTE: There is also a complete manual for JBoss rules, this wiki supplements the formal manual (see below for links).

Samples

Its important to note that the default textual language input for Drools 3 is a non XML format (XML support will be coming shortly as an alternative). It uses an Antlr3 grammar to parse rules and compile. See the RuleLanguageFAQ for some more info.

There is an examples project you can download.

Wiki guidelines

  • Feel free to edit/add to this wiki - the aim of the wiki is not to be a manual, but to be a general "catch all" area for helpful tips and links. Also, articles and documentation may be entered here first, when its ready, it will then be formally moved into the manual for future reference. In the old Drools web site, the wiki was also the documentation, but for Drools 3 onwards, we are providing a formal manual for this purpose.

  • Many tips are from real world deployments, add more of your own  Feedback/contributions are always appreciated. Its a wiki !

 

 

.Net version

  • Information can still be located here
