Hi, I want to store and then load rules from the database. I have seen that this topic is already been discussed here but i did not understand that completely that how can i do that. Can you please tell me the basic requirements, what tables do i need to make,how can i parse that data into a rule file. I have also seen a thread supported by Sujit and Micheal, i think it is the same project which is discussed in this post. this project kind of suits my requirement but the problem is that i am not able to get the whole idea how to store and then load that back from the database to make a drl file for rule engine. I also need a interface to get the input from the user if he wants to add a new rule to the file. and user is non technical. I am not getting how can i get the data and make that a rule for e.g. when b:Feature(featureClass.name=="FrontSuspension") c:Feature(featureClass.name=="FrontAxle") eval(b.attributes.Capacity>=c.attributes.Capacity) then AvailabilityRuleState s = new AvailabilityRuleState(); s.setValue("A");//Available s.setReason(""); s.setReference("FA-FS:1"); resultState.add(s); end i have read article by Sujit Pal and code for this project is not there at the link. Still got that code,but i am not able to import that in eclipse so dint run that.The only relief is that all rules are on one single class named Feature. as i saw in web interface images that whole package path was written in one field. http://docs.codehaus.org/display/DROOLS/Loading+and+managing+rules+dynami... http://drools-java-rules-engine.46999.n3.nabble.com/Writing-rules-using-j... http://drools-java-rules-engine.46999.n3.nabble.com/Storing-rules-in-a-da... http://drools-java-rules-engine.46999.n3.nabble.com/How-to-Access-and-Exe... these are the posts already in the forum. Please help me out. Thanks Navdeep
