I'm a student from Software School, Fudan University, Shanghai, China, and I'm interested in mobile software development for years, and recently I'm addicted in jabber, the most powerful and promising IM protocol. I have read a lot of materials about jabber everywhere and have tried many clients(both on PC and mobile), now I want to develop a jabber client on the mobile, but I am facing some difficulty which prevents me from moving forward.
As is known to all, Jabber server supports only socket connection to the client, however, for the time being, the majority of the java mobile devices on the market are based on MIDP1.0, thus supports only HTTP connection, as a result, the mobile jabber client cannot connect to the jabber server directly, that's to say, a web server ------ mobile gateway needs to be set up between the jabber server and mobile clients. I've found some commercial companies which have integrated mobile clients to the whole platform are using this method to support mobile clients.
Now that the mobile gateway is needed, how can I design the mobile gateway? Should the mobile gateway acts as an virtual client and opens hundreds of socket connections to the jabber server? In this way, each socket connection is mapped into a remote mobile client user, and each connection requires several threads(write thread, read thread, listening thread, etc.). Is this reasonable? Is it possible to create hundreds of new threads in web containers such as Tomcat? Or is there any other solutions? I need your help!! Thanks!!
