Thanks for your answer.
I have "Jess in action" (great book !!! many thanks for it) and so, i

Many thanks for your answer

This topic is treated in the book "Jess in Action", and of course if
you've got a Jess license, you've got the source code, which includes
the class jess.ConsolePanel which shows how to use TextReader and
TextAreaWriter . But the number one problem people have with this kind
of thing isn't really a Jess problem, but a problem of not
understanding that in Java, all GUI events are handled in a single
Thread, and if you block that Thread, no other events can be handled;
so in particular, if you call jess.Rete.run() directly from an event
handler, then the GUI will be frozen until Jess is through
running. You need to create another Thread and run Jess from there. As
I said, this isn't really a Jess thing -- it's just a Java programming
thing.
