Re: [rules-users] Check if fact is subset of items in the rule

Michale Thanks for the response. Here's the link for the thread . http://drools-java-rules-engine.46999.n3.nabble.com/Check-if-fact-is-subs... and the original about matching strings in two arrays. http://drools-java-rules-engine.46999.n3.nabble.com/Matching-strings-in-t... My use case is that I could have hundreds of rule and each rule could have its own set of strings. A fact object is run through these rules to see which ones are fired. One of the condition to check is that the a list in the fact is not a subset of list in the rule. That is fire the rule only if list in fact is not a subset of list in rule.
