Sprint Developers

I am developing the J2ME application.
Motorola Nextel i265 ( Sprints Provider )
Mobile: [b:f9b6df5d12]Motorola i265 [/b:f9b6df5d12]
Client Side: J2ME
Server Side: .NET ( I can change my language if I got solution from other language )

In my application I need the facility to launch the J2ME application on the server request.

[b:f9b6df5d12]Scenario is: [/b:f9b6df5d12]

Server will send the ?Service request? to the client Mobile
On Mobile J2ME application will be activated on this service request.
Mobile application will send response to server

[b:f9b6df5d12]Problem I am facing is [/b:f9b6df5d12]

I am not getting how to implement this
Somewhere I read about ?Push registry?, but I heard that i265 does not support the Push registry.
My client is saying that his mobile node will not necessity connected to the Internet ( that is not continuous GPRS connection)
Now I think only way is to send SMS. My client is insisting me to use the SMTP protocol to send the mail.

Please help me to find the solution for this problem. I am stuck on this issue.

Note: ... if any other way than SMS to launch the client side applicaion please send me information for that also

Additional Details

Here are some more details what exactly I want ...

1. there is a Mobile Application ( in J2ME for Motorola i265 )

2. Server application in .NET

3. Currently Normal Mobile to Server data transfer is working well with HTTP Post.

4. Now I want a functionality so that somehow Server can lauch the my Mobile applicaion.

5. Important thing is ( I can change this conditions if I got proper solution)

--- Mobile may not necessarity have GPRS all time. So I think I can't use the
TCP/IP packets.as that will require Continuous GPRS ( ? Is this right I think so ...)

-- there is something called Push Registry in the Mobile Applicaion world. here I need to send the SMS to the particuler Port on the Mobile. Now I dont know how to send the SMS to ports.

If yoy have any other solutions for this problem please do reply me.

Thanks & regards
