I am creating a web application using JSP and Servlets which enables users to chat using JMS. I need to know how to know the solution to the following situation:
user1 and user2 are chatting with each other.
when user1 sends a message to user2 I use JMSQueue to insert the message at the server end.
But user2 retrieves the message from the queue only when I manually refresh the page or set the page to an autorefresh using a timer.
Please suggest how to overcome this drawback ie. how can I retrieve the message at the client end which is user2 only when the user1 submits the message ?
[P.S. Guys ....have you people stopped using JMS 4 IM services or what as all the posts date back to 2001....!!!]
Thank you Sherriff ...... I am presently using polling to keep the service in working condition. But I need to be sure
that there is nothing more I can do programatically ....... also I need to know if there is ANY free technology available to mantain connections......
