Apologies. Apparently, I didn't test my link. It should have been this which would have taken you here.

The first link is Sending and receiving GSM SMS on Blackberry using RIM APIs ...

The third link is How to send SMS using java in Blackberry? - BlackBerry Support ...

The intent of my post was that you could (with a little effort) have found this yourself. If you want to write code, you have to be able to research. Putting "java send sms blackberry" into Google seems like a logical first step.
