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

I’m confused (not surprising) This code worked in 5.0.1 but Lisa indicates that it didn’t work for her on 5.2 (I haven’t tried 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?**** ** ** *From:* rules-dev-bounces(a)lists.jboss.org [mailto: rules-dev-bounces(a)lists.jboss.org] *On Behalf Of *Wolfgang Laun *Sent:* Friday, June 17, 2011 8:59 AM *To:* Rules Dev List *Subject:* Re: [rules-dev] Today's Eleusinian mystery: deserializing a package forchange set monitoring**** ** ** ** ** On 17 June 2011 16:34, Joe White <Joe.White(a)recondotech.com&gt; wrote:**** Not that it necessarily needs to be fixed but in 5.0.1 you could serialize a package just using a regular ObjectOutputStream.**** No - the code was not writing anything to a file. **** Also the guy**** || Lisa! **** Good point.

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**** ** ** _______________________________________________ rules-dev mailing list rules-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-dev
