I think the reason no one replied to this the first time you posted it was that we would need some more clarification on what exactly you want to know. Adding "URGENT!!!" to the subject line doesn't make your questions any easier for us to understand. It sounds like you've jumped into writing some Java code to generate rules automatically, without any understanding of the Jess language or Jess rules. This is really not going to work: you need to walk before you can run. Make a nice cup of tea, sit in a comfy chair, and read the whole manual. Look through the examples. Write a short Jess program or two. Then read the manual again. Then, and only then, you might think about writing a code generator! > As per the explanation given by Mr.Friedman, i think that the DISCOUNT would > be a global variable and not for that particular rule. > ( If 2 rules ( for different sales values ) have 2 discount rates , how are > these 2 differentiated.? There are deep architectural questions here, but I can only give you very shallow answers until you have a better understanding of Jess's capabilities. > > 2.

Jess decides when and how to fire rules all by itself. Again, you need to get a better understanding of how Jess works. > 4. Also how would the output be retrieved? As I've said before, there are many ways to do it. The first step, though, is to learn enough about Jess such that you can define what you mean by "the output." > 5.

A deftemplate is like a class definition in Java, and a fact is like an object.

Most likely, yes, but this is your program, it's up to you. > then a rule should fire and I should get the discount as 10% . I think I can > use the STORE function . pls verify ??? (store) is one of many ways that such a rule could pass the computed discount back to java. > But then how is the LHS being constructed ( the syntax ). Please provide me > some help on this regard.
