A (dynamic) "request" with a "logical expression" that is to be evaluated as a rule is very much like a (dynamic) SQL query to be evaluated on a database. Are you sure that Drools is the right platform? If "someone" wants to send a logical expression in a formal language of their own, you'll have

Sorry, I forget to mention one thing. What's really difficult for me is to translate the "AND","OR"(Condition 1 AND Condition 2 OR Condition 3) to the drool. Because someone will send the request with the expression(Condition 1 AND Condition 2 OR Condition 3) to me. For each request the exp

You don't need a file, you need a String (not to say you couldn't use a File if you really, really wanted - just that you don't have to). Other than the Fluent API already mentioned there is no Drools API to construct a DRL String. Read the manual, understand *your* data and build DRL applicable.

Hi Michael, Thank you for your reply~ Now, I understand some mechanism of building dynamic class.

There is one (1) sentence and a dozen (12) lines of example in the section about "What is New and Noteworhty in Drools 5.2.0" in the Introduction manual.

The reason it is not in the manual yet is because it was not promoted to the public API yet. Nevertheless, you can use it, but be aware that there might still be changes on it from version to version until it is promoted to the public API. I am hoping Mark will give me the go ahead to make it

1) No you don't have to save it; just use one of the overloaded methods on KnowledgeBuilder that takes a StringReader, or String or something else similar. 2) I understand there to be one for Drools Expert too, which I'd expect to be in one of the drools-xxx JARs however am having trouble finding

Yes. If the data "defines" the rules then there are numerous options:- - Construct a DRL String yourself and pass this to a KnowledgeBuilder - Use the fluent API to build rules programmatically - Construct an XLS decision table using your favourite XLS (Java) API and look at drools-de
