Hello Ernest,
Here's where the problem lies. The one-engine/one-user architecture is
inherently inefficient. The simplest change that would improve things
would be to still use one engine per user, but as you suggest, cache
the engines with the rules loaded. A (reset) before each user would
be

Hi,
I am facing a problem when attempting to use jess in my java Application
I've defined the output and the input router but, once i lanch the code in
jess, i have the print in my TextAreawriter but when the code is asking
for an entry ,something like (assert (fact (read)), the system
I'm trying to use JDom to emit XML from Jess. The
org.jdom.output.XMLOutputter.output() method requires an OutputStream
parameter. I'd like to use System.out, but I can't figure out how to pass
this as a parameter.
Here is a simplified snippet of what I am trying to do...

Don't know what you mean by is incorrect, but I'll guess one of two
things: first, you've written this as is there were independent
productType facts. Is this the case, or is productType a slot in the

Hi Jason,
I'm also a new to using jess and I have a trouble... You say to use eq
to compare objects,symbols and references. I have this problem:
(defrule myRule (myPattern (mySlot slotValue))=...)
where slotValue isn't a primitive type but a generic java object bounded
to jess variable
How I
Thanks for your answer.
I have Jess in action (great book !!! many thanks for it) and so, i
also have the jess61p4. ;-)
I agree that it was more a java problem as i have solved it now.
Many thanks for your answer

You do indeed need to override the hashCode() method, too.
