RE: global hivemind service
Yes, of course. You can implement your own service models however you want. You could store an implementation object in a database if you really wanted to. I meant that Tapestry doesn't (out of the box) have support for that feature. You have to be careful, though. Using session-scoped implementation objects does still have its drawbacks. If a user submits two requests from the same session, you can screw up your session-scoped data (just as you can with any session-scoped data). There are ways to avoid this, of course, but you just have to be careful. -Original Message- From: Jean-Francois Poilpret [mailto:[EMAIL PROTECTED] Sent: Wednesday, July 26, 2006 9:33 AM To: 'Tapestry users' Subject: RE: global hivemind service If you allow me James, although HiveMind does not provide a "session-scoped" or "user-scoped" service model, you can find external implementations out there...

RE: global hivemind service
if you declare a service as model="threaded" a new instance will be created for every request of a new thread. so every thread has its individual instance. i think model="singleton" (default model) is what you are looking for. you could also define a application state object with application scope: http://tapestry.apache.org/tapestry4/UsersGuide/state.html#state.aso g, kris xVik <[EMAIL PROTECTED]> An 26.07.2006 14:06 users@tapestry.apache.org Kopie Bitte antwortenThema an global hivemind service "Tapestry users" <[EMAIL PROTECTED] pache.org> i need to have global hivemind service (the only for all threads (and all users)) im not shure that treaded model is what i need more dataily: data generated by this service (sitemap for example, stored in some collection) should be accessible by all working threads (and not recalculating for each user) am i right threaded is what i need? -- View this message in context: http://www.nabble.com/global-hivemind-service-tf2003454.html#a5501986 Sent from the Tapestry - User forum at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
