hi, Im working on Drools project.here is my project scenario. front end : Adobe Flex 3.0 application server : tomcat 6.x Drools : 5.0 from flex application i was invoking java class which isin the server "DroolsTest.java" . In this i was dynamically creating a class ( Fact ) ,compiling it and creating a rule ( a simple test rule). To run the Rule i also created "StatefulKnowledgeSession" in that i added facts from dynamically compiled class. up to this point i was succeded. now when i call ksession.fireAllRules() it is not displaying any message from rule engine.i have done several trails and no luck... Added the following JARS in WEB-INF\lib antlr-runtime-3.1.1.jar core-3.4.2.v_883_R34x.jar drools-api-5.0.1.jar drools-core-5.0.1.jar drools-decisiontables-5.0.1.jar mvel2-2.0.10.jar drools-compiler-5.0.1.jar xstream-1.3.1.jar suggest me any ideas . regards Hemanth -- View this message in context: http://www.nabble.com/Drools-engine-not-working-tp26004131p26004131.html Sent from the drools - user mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
