Re: [rules-dev] Today's Eleusinian mystery: deserializing a packageforchange set monitoring

Never mind. Just tried it and it worked with a simple rule. She must be doing something else with it.

FileOutputStream fos = new FileOutputStream(drlcFile); ObjectOutputStream oos = new ObjectOutputStream(fos); oos.writeObject(pkg); oos.close(); And that code does write to a file. Should this work in 5.2 or shouldn't it?

No - the code was not writing anything to a file. Also the guy || Lisa! Good point. My bad. -W on the user mailing list was getting an exception using the DroolsObjectOutputStream.

However, you can't simply serialize an org.drools.definition.KnowledgePackage as it is usually done by writing it to an ObjectOutputStream: deserialization in the KnowledgeAgent throws a CCE exception. To make it work, you must use a DroolsObjectOutputStream, which is nothing but a rename of ObjectOutputStream. So I have use DroolsObjectOutputStream, but it is not part of the public API. -W _______________________________________________ rules-dev mailing list rules-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-dev
