Sorry for resending the message. This is an urgent issue and if anybody has encountered this problem, can you please let me know how it can be resolved? If I have over 3 packages in the RuleBase and I try to remove one of those packages, then I get a NullPointerException. Thanks. ________________________________ From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of Sarika Khamitkar Sent: Wednesday, July 11, 2007 3:34 PM To: rules-users(a)lists.jboss.org Subject: [rules-users] NullPointerException while deleting the rule package Hi, I am trying a remove a rule from the RuleBase using the following syntax and get a NullPointerException: ruleBase.removePackage("rule2392016206"); Before removing the package, I am iterating through all the packages in the ruleBase and I can see this package name in the list. I am not sure why this exception is being thrown then. I am using 4.0 MR3. Has this feature changed since 3.0.6? Thanks.
