Re: [rules-users] Rules Firing / Java Objects Not Manipulated

Hi, I am new to Drools and Guvnor, so I am likely overlooking something simple. I am prototyping a proof of concept for integrating Drools into SOLR and using Guvnor for business rule management. I have a Guvnor generated rule that looks like this: rule "t1" dialect "mvel" when SearchState( searchTerms == "monitor" ) then SearchActions fact0 = new SearchActions(); fact0.setUrlRedirect( "junk" ); insert( fact0 ); System.out.println("Created junk!!!"); end In a custom SOLR search component, the Drools POC integration code is as follows: try { if (rb.stage == ResponseBuilder.STAGE_START) { // load package kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); kbuilder.add( ResourceFactory.newFileResource(new File("c:\\data\\guvnor\\searchLatest.pkg")), ResourceType.PKG); // create the knowledge base kbase = KnowledgeBaseFactory.newKnowledgeBase(); // add the package to the kbase kbase.addKnowledgePackages( kbuilder.getKnowledgePackages() ); System.out.println("In QueryInterceptorComponent.handleRequestBody(). q = " + rb.req.getParams().get("q")); StatelessKnowledgeSession ksession = kbase.newStatelessKnowledgeSession(); SearchState searchState = new SearchState(); searchState.setSearchTerms(rb.req.getParams().get("q")); //More search state attribute setting here ... Collection list = new ArrayList(); list.add(searchState); ksession.execute(list); System.out.println("EXECUTED RULES"); } } catch(Exception e) { System.out.println("Caught exception " + e); } Running in Debug mode on Tomcat and searching on "monitor", I can see that I step through all of the code above without any exceptions. The console output shows me that the rule successfully fired and that the When condition was satisfied as it performed the When side of the rule; it wrote the sysout message I expected. In QueryInterceptorComponent.handleRequestBody(). q = monitor /*Created junk!!!*/ EXECUTED RULES But when I then access the list collection again in the debugger, there is no SearchActions object added to the list. I've also tried modifying the rule to just change a value on the SearchState object that is driving the When condition. That doesn't result in any object changes either. Can someone point me in the right direction? Again, I'm new at this. Any assistance most greatly appreciated.
