How to programmatically load rules from a Kie jar lying in the classpath of an application like a WAR ?

Solution Unverified - Updated -


  • In Red Hat JBoss BRMS 5.x rule assets (archived in a jar) could be loaded from the classpath of an application (like WAR) using KnowledgeBuilder as shown below.
KnowledgeBuilder kBuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
KnowledgeBase kBase = KnowledgeBaseFactory.newKnowledgeBase();
kBase.addKnowledgePackages( kBuilder.getKnowledgePackages());

Are there similar ways to do the same in Red Hat JBoss BRMS 6.x as well, where rules can be programmatically loaded from a Kie jar lying in the classpath of an application like WAR ?

  • Will it work in an environment of Websphere Application Server 8.5.x as well where the WAR containing the code and the rule jar (i.e. a Kie jar built in Business Central) is in exploded form ?
