> That looks REALLY interesting...thanks for the pointer. Yeah, this does look interesting. I happen to be neck deep on something like this (it's next on my stack). I had planned on doing the "automatic refresh" style, rather than the constant pushing of the data. The reason I decided on this technique was simply timer resolution. Since I can (ideally) get a refresh of 1/sec, the question was whether that was a fine enough resolution. For me, I decided it was. Also, I don't have to worry about losing the connection or restarting the task (like when they hit the Reload button). The hard part, IMHO, is getting the Long Task to be asynchronous, and report back the "almost done" status. Since my app is backed up by a J2EE server, I'm, technically, not allowed to use threads. We have a "Cron-like" process outside of the server, but it's resolution is pretty coarse (every few minutes), so I need something else. I'm debating on trying JMS, but then I need to have several JMS clients waiting for requests so I don't serialize the processing. And, we're not running J2EE 2.0 yet, so I can't using a MessageBean. Bother. So, for me, the display part is easy. A simple http://myapp.com/status?processid=12345 can return a simple populated form by querying the DB for the Latest Update in a hidden frame. The back end is the Hard Part.
