I disagree. Many large Rete-based systems have been built on machines with a smaller memory map than Java's flat 4GB (2GB on Linux) heap. His 250,000 rules could very easily be compiled into a Rete network that would fit with room to spare. As long as he doesn't have any highly combinatorial rules (so that he needs a whole lot of core for partial matches) I wouldn't be at all surprised if he could get his system running in a 32-bit address space. > Also, you shouldn't use Java > 1.4 with any system that uses the "assert" key word - such as JRules - because > I've been told that Java 1.4 wants to use it as well. "assert" is a keyword in JDK 1.4, but if you use it in Java source and feed that source to JDK 1.4's "javac," it will emit a warning and simply drop into a compatibility mode for that source file. Your code will compile perfectly. In other words, as long as you're not actually trying to use JDK 1.4's new assertion facility, there's no problem at all. JDK 1.4 is an impressive achievement in many ways, and so not using it for this trivial reason would be a shame. --------------------------------------------------------- Ernest Friedman-Hill Distributed Systems Research Phone: (925) 294-2154 Sandia National Labs FAX: (925) 294-2234 PO Box 969, MS 9012 [EMAIL PROTECTED] Livermore, CA 94550 http://herzberg.ca.sandia.gov -------------------------------------------------------------------- To unsubscribe, send the words 'unsubscribe jess-users [EMAIL PROTECTED]' in the BODY of a message to [EMAIL PROTECTED], NOT to the list (use your own address!)
