Ladies and Gentlemen, 

I'd like to know the best way of inserting an existing Bean into a
running Rete engine.

I'm working on a Jess-based system to govern access to controlled
documents.  I'll have a large number of users and an immense number of
documents, so I can't store them all in memory.  Furthermore, user
permissions will be set locally at hosts throughout the network, each
user's permissions can change frequently, and documents will be
distributed across many servers.  

To address these requirements, I plan to store user permissions and
document descriptions as beans.  When a user requests a document, the
beans describing the user's permissions and the document's
descriptions will be serialized and sent to security modules containing
the Rete engines. I'll assert the facts describing user permissions and
document requirements, run the appropriate engine (There may be more
than one.), and return a decision whether or not the specific user may
hold the specific document.  Jess's ability to deal directly with
beans is a Real Good Thing for this design.

My problem is that I don't know a good way of making the Rete engine
aware of the beans.

I've seen examples of how to create beans in Jess and how to extract
bean properties directly from Jess to Java, but I haven't seen any
examples of how to insert a bean into a running engine.  I'm sure it
can be done with "store" and "fetch", but I'm wondering if there might
be a more elegant solution.

Please feel free to flame me with "RTFM" as long as you tell me where
in TFM to R --- and agree to take questions afterwards.  I have R'd
TFM and I haven't found the answer.  (But who knows, perhaps my son is
right and I am senile already.)

Thanks for reading my request.

Peter Olsen
