Hello, I have two questions. Hopefully they are very simple:
1. If I wanted to dynamically update a package in the RuleBase because I found out that the drl was updated on disk, can I just do this: ruleBase.addPackage(myPackage); And this will automatically replace (remove the old one, and add the new one)? Or do I have to implicitly first remove the existing one and THEN add the modified one again? I have the following code: if (ruleBase.getPackage(onePackage.getName()) != null) { ruleBase.removePackage(onePackage.getName()); } ruleBase.addPackage(onePackage); Is this a code practice to do? 2. My second question is, the statement above in the body of the IF block, threw the following exception: Exception in thread "AdminHandler_0_123877285495354" java.lang.NullPointerException INFO|7032/0|10-06-10 13:43:55| at org.drools.reteoo.ReteooBuilder.removeRule(ReteooBuilder.java:235) INFO|7032/0|10-06-10 13:43:55| at org.drools.reteoo.ReteooRuleBase.removeRule(ReteooRuleBase.java:413) INFO|7032/0|10-06-10 13:43:55| at org.drools.common.AbstractRuleBase.removeRule(AbstractRuleBase.java:729) INFO|7032/0|10-06-10 13:43:55| at org.drools.common.AbstractRuleBase.removePackage(AbstractRuleBase.java:657) INFO|7032/0|10-06-10 13:43:55| at [statement in the IF block above] Any ideas why that is?
