Are you using the same Drools jar versions on both sides?<BR>> <BR>> -----Original Message-----<BR>> From: rules-users-bounces@lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of dhai<BR>> Sent: Monday, April 20, 2009 8:59 PM<BR>> To: rules-users@lists.jboss.org<BR>> Subject: [rules-users] RuleBase deserialization throws NPE<BR>> <BR>> <BR>> We have application that has two parts. One is for authoring the rules and deploying RuleBase into database. Second reads that sterilized RuleBase from database and evaluate the rules. I am randomly getting NPE while I desterilize RuleBase. Its very inconsistent. The test data and environment in same. Once I get one NPE while performing 2000 transactions and second time I receive same exception after 500 transactions. The first test was executed in single threaded and second was in multi threaded. <BR>> <BR>> I was wondering if some one else had encounter same problem.
