7 close hi how are you today <b>(SORRY FOR MY BAD ENGLISH)</b> i want to sent data from Server to J2ME (using Java) but i don't know when the server will send the data to my midlet so how can i built a listener in midlet that listen to the resposne from server by (sure that response will receive using HTPPCOnnection) plz help me , i need the solution and tyvm.

IP traffic is based on two ends of the communication chain. TCP is built on IP. TCP has a 'client' and a 'server'. The client connects to the server (this has nothing to do with what the applications that contain the functionality are named.) HTTP is built on TCP. So in answer to your question. 1. You must have a 'server' that handled HTTP. 2. You then create a 'client' which sends HTTP requests to the 'server'. You can't do anything unless you have both parts. The server cannot be transitory. It must basically be up all the time. In other words it cannot come into existence only once a client sends a request.

Why? If you want the mobile to act as a client (and you can use sockets) then your question is meaningless. If you want the mobile to act as a server then you must have an IP that is visible to the client. This however in general isn't what mobiles do but if it has the IP and sockets (which it would if it has an IP) then it is possible. Whether it is visible is a different issue. Other than that you are asking a question about a specific mobile device because they are all different. It is pointless to ask how to do something on a mobile if it does not in fact have the minimum capability to support the solution. And whether it has Ip is not something that you determine with Java. Instead you look at the specification of the mobile itself.

And I already told you the most significant part of the problem. You must determine what the mobile can do. That isn't a java question. It isn't a question you can answer about a "mobile". You need to ask it about a specific (vendor) mobile.

the program using emails on Hotmail
That at least makes it likely that it can act as a client.

I suggest you write the code, client and server on a desktop first.
