Re: [rules-users] Comparing KnowledgePackages for Equality

I am using Drools 5.3.1.Final in case that is useful information. Thanks Esteban for the suggestion but I could not get that to work. I must be doing something wrong. Here is what I am trying to do in a nutshell. I read in several standard rules and guided rules, add them all to a KnowledgeBuilder, and then get the resulting KnowledgePackage from the KnowledgeBuilder. I then save this KnowledgePackage to a database using Hibernate. My problem is now every time I read the package from the database Hibernate thinks the object is dirty and updates the rule package. A byte comparison of two packages does not work because you are not guaranteed everything in the package will be serialized in the same order, as I found. To test this I deserialized two packages from the same byte stream, serialized them, and all resulting byte arrays were different. When I tried Esteban's idea I read the KnowledgePackage from the database but all the rules in the package do not have a consequence until I add the package to a KnowledgeBase. This means that I cannot use a BinaryResourceDiffProducerImpl because that compares rule consequences and throws a NullPointerException in my case. Any other ideas on how I can successfully compare two KnowledgePackages that represent the same set of rules or even another suggestion altogether to get KnowledgePackages to play nicely with Hibernate? -- View this message in context: http://drools.46999.n3.nabble.com/Comparing-KnowledgePackages-for-Equalit...
