Title: RE: JESS: JESS & EJB

I'm curious what type of applications you guys are using the engine for.  We are investigating the JMX route because of the "normal" EJB rules.  For example, how do manage state?  The engine use we are working toward is going to be a run-all-the-time service.  Just because the engine maybe quite for a given time, I can't have the container running around trying to kill it off.  Now, I admit to being a bit under-acquainted with J2EE as a whole, but how else does one use/model the engine? I suppose if your rule base were small enough and a persistent state was not required for long periods of time, things might be more straight forward?  Comments?   James   ----- Original Message ----- From: Bryan Talbot To: '[EMAIL PROTECTED]' Sent: Thursday, February 28, 2002 2:49 PM Subject: RE: JESS: JESS & EJB -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've also been using JESS within EJB's for a couple of years now.  Can't say that there is anything special to talk about.  The engine is just another java object aggregated by the bean implementation as usual.  I, however, did maintain the JESS scriptlib.clp file access along with a small number of other .clp files that are read upon initialization.  I had to do nothing special to make JESS work within the EJB environment other than following most of the "normal" EJB rules.  I'm using Weblogic 5.1 and JESS 5.0.   - -Bryan     - -----Original Message----- From: Moore, David (GXS) [mailto:[EMAIL PROTECTED]] Sent: Thursday, February 28, 2002 11:52 AM To: '[EMAIL PROTECTED]' Subject: RE: JESS: JESS & EJB I am using Jess from within some stateless EJB's.  The only thing I had to do was change the source code to not load the standard scriptlib.clp - file I/O is considered bad form inside an EJB.  I have my rules stored in a database and the user can pass XML to the EJB, which I turn into a fact and then return the appropriate response as determined by Jess. David Moore - -----Original Message----- From: rhalsey007 [mailto:[EMAIL PROTECTED]] Sent: Thursday, February 28, 2002 9:01 AM To: [EMAIL PROTECTED] Subject: JESS: JESS & EJB Has there been any expression of interest (or any work done) in the integration of JESS with EJB (J2EE) ?? I have looked through all the JESS V6.0 documentation, but found nothing. Also, I have conducted multiple searches on the web for JESS and EJB and found one article on E++ which mentioned using JESS as a stateless bean. What has got my interest up is the fact that ZeoSoft is using JESS as the inference engine for their ZeoFusion product and this product interfaces with an application server for PDAs !! http://www.zeosoft.com Is there any information out there on JESS/EJB ???
