It is my intention to build all rule packages in Guvnor (or some other process) before deploying the packages to a production environment. I see that I can use a KnowledgeBuilder with a PKG type resource to create KnowledgePackages, and then initialize a KnowledgeBase with the KnowledgePackages. Though this should do the job for me, is there a way to setup the KnowledgeBase with the compiled packages without using a KnowledgeBuilder? My desires are to keep overhead to a minimum and optimize performance during the initialization step. In Drools 4, I did this with RuleBase.addPackage using java's standard serialization techniques. but am uncertain if I can use KnowledgeBase.addPackages the same way. I assume the binary packages that are built with Guvnor uses the new drools serialization, so I need to know how to use that to serialize and deserialize packages as well. Thanks in advance for any help. -- View this message in context: http://www.nabble.com/Using-compiled-packages-tp22070145p22070145.html Sent from the drools - user mailing list archive at Nabble.com.
