Hi Carlos, 1) Can this be done dynamically? I meant, will the workflow change as soon as I save the new rules on any pre-existing package? No, you have to re-build the package manually. There is some REST API you can use if you want to add some degree of automation. 2) Would this allow me to add workflow steps and rules as well as general data entities? Not sure what you mean by "workflow steps" here. You can have a mix of declared and imported (from a jat) entities. 3) What should I have in me interface to be able to use Drools as me rules engine? I don't get it yet... Drools is just a framework, so you will need to embed it in your application. The basic steps are: //1.- Create a kbuilder KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); //2.- Add resources to kbuilder: you could use different Resources and different ResourceTypes too kbuilder.add(new FileSystemResource("./event-rules.drl"), ResourceType.DRL); //3.- Create a kbase KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase(); //4.- Add packages from kbuilder to kbase kbase.addKnowledgePackages(kbuilder.getKnowledgePackages()); //5.- Create a session. ksession = kbase.newStatefulKnowledgeSession(); //6.- Play with the session ksession.insert()/update()/fireAllRules() etc. If you are planning to read the rules from guvnor you can use an URLResource in step 2.
