RE: JESS: Jess Java
Hey All: This is my first Post. I never had any experience with Rules Engine. The project that I am currently working is using Home Grown Rules Engine. My Friend Prasath ([EMAIL PROTECTED]) developed the Rules Engine single handedly. His Rules Engine uses Excel for defining Rules. I was very much interested in knowing about Rules Engine. After searching in Net , I found about Jess. So I went to borders (Bookstore in US) and got JIA. It was great book for beginners like me. It gave a very good introduction about Rules Engine.I am half way through the book. So be ready people, I am going to storm this mailing list with questions. But importantly I will do my best to help others in this mailing list.

Re: JESS: jess/java question
Hi! Is there a way for me to in a jess function(deffunction) pass something back into my calling java program? Once I get a rule to fire, I need to be able to get the information to change the XML back to my java code. Or somehow be able to change the XML. I am open to any ideas. An XML document is a collection/hierarchy of objects (nodes) that are usually accessible through the standardized DOM (Document Object Model) API. You can pass object references to Jess (see documentation). Your options then range from pure Jess script to (almost) pure Java: 1) Within your Jess script you can call a Java object's methods. Thus, you can also modify your XML document from within a deffunction or directly on the RHS. 2) You can write Jess Userfunctions (in Java) that perform the necessary modifications. You'd use these Userfunctions in your script. 3) You can write a normal Java class that performs the modifications. You'd call its method(s) the usual way.

RE: JESS: jess/java question
Bob, Instead of copying the XML document data into facts, you should definstance the XML DOM nodes and have your rules pattern match directly on the node/element/attributes, etc. The jess (and java) syntax gets a little ugly when working directly with XML DOM but it is workable. A better approach would be to use JDOM which cuts down on the node/element/attribute traversals quite a bit... However, if you don't want to change your current setup, you can simply assert the XML DOM (or JDOM) nodes as an additional slot in the facts/instances you are already creating. This slot would presumably be an external address: new Value(xmlNode, RU.EXTERNAL_ADDRESS); and then you can access and manipulate the xml node just like any other java object in jess: (defrule augment-empty-accounts (account (id ?id) (balance ?balance:( ?balance 0)) (xml-node ?node)) = ;; manipulate ?node using jess code (e.g. add attribute nodes, etc.) ) Good luck! alan -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Bob Stewart Sent: Tuesday, September 18, 2001 6:48 AM To: [EMAIL PROTECTED] Subject: JESS: jess/java question Hi, I am integrating jess into my EJB code. I am trying to create an XML document enhancement service. What I am doing is taking in the XML document as a byte array, turning them into jess facts, and running the rules against those facts. Based on the defined rules, I will want to change fields(change priority, add a comment) to the XML document. So far, I am reading in the XML document, and the rules are firing okay. I am just not sure how I can update the XML document. Is there a way for me to in a jess function(deffunction) pass something back into my calling java program?
