Wow. What a lot of responses I got. Thanks to all concerned. I'm used to getting little or no replies from the other lists I'm on.
For the record my environment is Tomcat (5.0.28) with Java 1.4.2. I do have a batch/queue system - I'm using Quartz https://quartz.dev.java.net/ (anyone else using this?) which I've wrapped up to do batches of "Jobs" held in a DB. I only use servlets or JSPs other that than. For some of my length tasks I have implemented both a servlet front end and a Quartz "Job" front end. This allows me to run things on-the-fly or in a "Job". I'm not using J2EE. That's another issue really, as my system grows I often wonder if it's outgrown the single-Tomcat, servlet/JSP environment. I've never used JMS - is this J2EE only? (I'll Google it later to see). I'm cranking out all of this stuff on my own, with no other Java developers in the company - so a move to J2EE would mean a massive upheaval. I can see how using a Session could be a way forward but I'll need to play with it before the penny drops. I guess I need to set some sort of polling up on the session to detect when complete - I don't want the user to have to do anything. I'm going to go and study these replies again! Thank again all - I may have some follow-up questions.
