Re: [rules-users] How to aggregate decisions of multiple rules?? (In Guvnor)

Re: [rules-users] How to aggregate decisions of multiple rules?? (In Guvnor)

Assuming that the engine is handling one set of facts at a time, I would use a single additional fact to collect all decisions. The details of this object may vary (depending on whether you have a constant number of rules or not). enum Decision { UNDEF, GRANTED, DEFERRED,... } class Collector {

Re: [rules-users] creating .pkg from .drl

Try to add all the packages to a kbuilder and then serialize the resulting packages. You will need to create a PKG per logical package though. If your DSLR and DSL files are in the same logical package, the kbuilder will only contain one package that you have to serialize. Best,

Ok, did that and it still only works when serializing using DroolsStreamUtils.streamOut and using a KnowledgeAgent to construct the KnowledgeBase from the serialized package, but it does work with multiple resources in the same logical package when serializing. Still fails when trying to use
