I am developing a Chat Application that is similar to Gmail Chat and also want to add feature like Chat rooms.
I came to know that some firewalls do not accept Socket Connections so i want to develop using Servlets.
Is my approach right if not,Can anyone help me by suggesting the strategy to implement the Web-based Chat application using Servlets.
Please suggest which APIs will be used to develop the web-based Commercial Chat Application.
The issue is not about refreshing the Page/using AJAX.Its about sending messages to a specified user on selection(just like GMAIL) from a user-List.
I explored socket programming where for each user a thread is created and the user is also assigned with a port number internally.This model limits the number of connections.
So i am thinking of exploring in JMS since Scoket Programming has its own limitations.
So i request if anyone could help me in building a Chat application (similar to Gmail one- one)using JMS(if feasible commercially).
I need to embed the Chat in one of my Java(portal) Application so i prefer using Java Apis like those i mentioned to send Chat messages from one user to another user.
On top of that i am still not clear how to proceed developing my chat application for my web/portal application.
