Hi!
Well, I think that the your technical design requirement can be developed using Ajax technologies. In J2EE we have e.g. DWR, http://getahead.ltd.uk/dwr/, to use Ajax inside web applications, but the problem could be the comunication server-client because the request to update data in client tier is thrown from server, this issue causes the need of a listener to attend server requests, in http://ajaxpatterns.org/Patterns#Browser-Server_Dialogue you can find information about dialogue patterns between client and server, also Ajax Patterns web site is a good way to start with ajax tecnologies.

That`s all¡

Regards, Ch.

Para: Struts Users Mailing List
Asunto: Real time data display in a struts based application.

All,
 
Have a design issue here. We have a web based application and have 2000 concurrent users. The requirement is: when new data comes on Oracle database for users this data has to be sent to the online users on a real time basis. Someway, the real time data needs to be pushed to the users without the client doing a reload/refresh etc.
 
What technologies can be used here ? Can anyone provide me some suggestions ?
 
The users login to the application using a web page, this is a web based J2ee application using struts, Oracle database.
 
Thanks,
Maya
