There requires some intellegent server which should understand the mobile protocol.

Hi Bharat,
I think a WAP Server(Motorola) configured with Web Server(Apache) is enough to setup a communication between a java and mobile.But most important is ur mobile shd be KVM enabled..thats it...Reply back if you want more info.
Correct me if'm wrong.,

I think most web servers can easy plug in a WAP module. For MIDP, and likely all other J2ME profiles, HTTP/S will be supported at a minimum.

actually all servers should be able to serve wap, because it is a text format you just have to add the appropriate mime types to the server and it should then be able to accept requests from WAP telephones. You will need a gateway to compile the wml pages into wmlc files. YOu will also need a RAS machine to send the files over the air.
you can get gateways yourself but you would need to set up rassing into the gateway. there used to be a whole load of free gateways to test your applications on but its a while since I have messed around with those and I am not sure of them any more.

Marks' right - if you're talking J2ME, which I guess you are since this is the J2ME topic, then all you need is an HTTP server, which is great news. No fancy WAP gateways, just plain old servlets is just fine.
Some devies will allow sockets and UDP too, but this isn't mandatory in the MIDP specification, which the majority of initial devices will adhere to.

From talking to vendors, I got the impression there was strong desire for this, and we will be seeing UDP and socket support in early devices. I've even heard the vendors talk about insuring that the optional protocols be defined, so they can adhear to common standarda. (I'll bet you never would ahve heard that 30 years ago :-)
Have you seen many devices in Europe and Japan that only support HTTP?

No, I have only got my sticky hands on a Motorola Accompli 008 so far, although rumour has it that Siemens will deliver a phone soon. The Motorola does have sockets, but not UDP. I haven't yet got around to testing them on the Accompli.
However, I can say that the Accompi is pretty good - better than I expected. Its a PDA that is phone-sized. I have replaced my PDA and old phone, and have missed very little. I have only one criticism of it - the performance when saving to MIDP storage (i.e. RMS records). Other than that its really good - big screen (240*238 useable pixels), GPRS-enabled, reasonble plain GSM connectivity performance, no crashes or lockups, even though it isn't the final software build.
