I have a question regarding to the swing and web application.
The swing application is used to monitor some activities happened in web application. For example, when a user is login the web application, a signal is showed in swing application the a user has login the web application.

The way I am thinking to implement is as following:
Using event and event listenet---When a user login, an event is generated from the web application. The swing application listens to the event, and perform some actions to show the signal. in order to have swing application receive event generated from web application, I think a connection between swing application and web application(localhost) should be established.

My Question:
1. How can I establish the connection between swing application and web application(assume web application and swing application is in the same machine).
2. Is the event-event listener approach correct in the above senario?
I really appreciate all your help and suggestions.
Best regards,
Ranch Hand

Hi Nancy,
Considering that both VMS are on the same machine (I am assuming that the web application is a servlet/JSP app) then I would suggest using RMI. The initial setup for both ends of the plumbing is a little more difficult than a pure socket solution, but once done then sending and receiving events is as simple as it is in a single VM.
Hope this helps,
Michael Morris

RMI is the best bet.. have the same worked out in a listerner/observer pattern where the call back to the swing application is thru RMI.
