There is no J2ME involved in your case! J2ME is a client side technology for creating applications that reside on mobiles. But, as you have stated you want to send SMS from servlet(s). You are better off with server technology as Servlets.

I haven't created such service but let me give you few pointers:

1. You require an SMS Gateway, which acts as an interface between the "Internet-world" and the "Mobile-netword".

2. Try to findout the providers for such service.

3. Find out how the messages should be forwarded to use their service?

4. I guess they will provide their own API classes to use the same.

Hope more information will be posted by others....

Cheers!!

The last entry in the http://faq.javaranch.com/java/JavaIoFaq has a few relevant links. Signing up with a provider will cost you money.

For low volumes, there are email to SMS gateways for nearly all the carriers (in the US). You can just send an email to an appropriate address. It varies by carrier. You just address it to something like

2025551212@mobile.att.net

Google will tell you the current gateways, I haven't looked for them in a couple of years.

You can send the email with the standard Java email API

Even if the cell phone provider supports an email-to-SMS gateway in general (not all do), any given number may or may not have this enabled, depending on the plan being used; so you can't rely on it.

I've never had it fail, but that probably doesn't mean anything.

I have heard of folks buying a cell phone and a USB cable, getting the unlimited message plan, and putting the cell phone in their data center. Its cheaper than any real SMS gateway
