RE: [rules-users] How to serialize a KnowledgeBase?

I'm not up to snuff on Drools 5.0 M4, however, there are two observations that I have in regard to your question: 1) Given the code that you provided, line 4 is wrong. You cannot use a static KnowledgeBaseFactory to instantiate a KnowledgeBase without associating the KnowledgeBuilder instance. This is where my knowledge of the APIs is not clear, but you will need to execute some additional logic to move the knowledge-base rules from the KnowledgeBuilder to the KnowledgeBase. 2) It's not clear what optimization that you are hoping to achieve by serializing the Knowledge Base. Does it take a really long time to load the drl? Also, have you looked at serializing the kbuilder? I don't know if it's possible for certain, but that would be the next place that I'd look.

Hi all, Im currently developing a new application using drools 5.0 M4. Im using this style (from KnowledgeBuilder javadoc): 1- KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); 2- kbuilder.add( ResourceFactory.newUrlResource( "file://myrules.drl" ), ResourceType.DRL); 3- assertFalse( kbuilder.hasErrors() ); 4- KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase(); Now, for optimization reasons, I want to save kbase. The problem is that it is not serializable. Probably, Im trying to serialize the wrong object. can someone please guide me how to do that? BTW, I have another question, How the KBFactory on line 4 knows the builder used in lines 1 and 2? Will it actually work?
