Sms to Java application

I am creating a final project from school that would have a main Java app that eg queries a database for a telephone number.
The beaty in it would be that the application can reveive its data from a java GUI, e-mail, http form (servlet or built-in webserver), irc and sms. I sorted everything out except for the sms part. I can't find an easy way to get a sms into the app.
An idea would be to send the sms to an e-mail adress and then do the same thing as with the e-mail module. However, how do I get an sms to an e-mail adress?
I know u can send sms to ICQ so it is possible, i also know u can attach a phone to a com-port on your pc and sms to that phone, then have a program runnong (COM Component from ActiveSMS) that sends it to the app.
Any ideas are websites that can do this? I did discover one but it is only for corporrate users and charges quite a lot.

PS: I know this is not J2me, it would probably be easy doing this in J2me but that would only serve those who have Java-enabled phones. I have one
