Lots of things to consider, especially if the operation needs to be robust. For instance, are you only keeping the jobs in memory? Are you worried about the system going down mid-operation? > With a progresiveDisplay I keep the user informed of the progress of > the operation (and possibly of the errors involved), my reference is > kept in a cookie so users could still log out and come back later. How important is it that this status is accessible? If your users "MUST" have access to it then I wouldn't stick it in a cookie. Can you stick the reference in the database? This also makes it so that the user can pull up the progress from another computer, say on the bus on the way home using their mobile device. > Now the Futures from my Invokables are within a MAP keyed to my > cookie-key and stored in the Service implementation. What happens when the processing is done? How long are you keeping the objects in the Map? If you restart the server all this information is lost so depending on your requirements you might want to keep some status info in the database. > May I ask if this solution sound reasonable to you? > > I already know this doesn't fit very well in a clustered environment > but it's not a problem right now... perhaps within 6-8 months. > > Thanks > -- > Massimo > http://meridio.blogspot.com > > --------------------------------------------------------------------- > To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org > For additional commands, e-mail: users-h...@tapestry.apache.org > > -- -- http://www.bodylabgym.com - a private, by appointment only, one-on-one health and fitness facility. -- http://www.ectransition.com - Quality Electronic Cigarettes at a reasonable price! -- TheDailyTube.com.
