<br>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. <br>
<br><br> when <br> b:Feature(featureClass.name=="FrontSuspension") <br> c:Feature(featureClass.name=="FrontAxle") <br> eval(b.attributes.Capacity>=c.attributes.Capacity) <br>
then <br> AvailabilityRuleState s = new AvailabilityRuleState(); <br> s.setValue("A");//Available <br> s.setReason(""); <br>
s.setReference("FA-FS:1"); <br> resultState.add(s); <br> end <br><br><br><br><br>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. <br>
