Yes, in the above code (new Consumer) creates a new Consumer object. You can replace that with any other Jess code to retrieve an object of interest. The store and fetch functions are one easy way to do this, but you can do it however you'd like -- e.g., using a static Java method or member variable to "bootstrap" a tree of objects into Jess. Once Jess has ahold of one object, you can use its methods and data to retrieve others. > > Since I don't know whether this is relevant, let's add the complexity > that we are iterating over a collection of consumer agents in the Java > code and firing that rule in each iteration.
