Hi all, I am new to drools. I am facing a very strange issue while working with JDeveloper + OC4J 10 + Drools 4.0.7. If I execute my "hello world" program in "debug" mode of JDeveloper then all my rules are working properly. But when I execute it in "run" mode then execution stops at following line builder.addPackageFromDrl(new InputStreamReader(CreditExample.class.getResourceAsStream("/abc.drl"))); Also there is no exception thrown. I don't know what is the problem at run time. Can anyone please help me out Thanks Vir -- View this message in context: http://www.nabble.com/Drools-4.0.7-%2B-OC4J-tp23190680p23190680.html Sent from the drools - user mailing list archive at Nabble.com.
