How to Switch to OTA Provisioning option in Wireless toolkit J2ME? - java-me

Question

I am new to J2ME and now I have to solve one J2ME project.
Below is my login form I don't know what to do with that but it is giving me the error "javax.microedition.io.ConnectionNotFoundException: TCP open". After searching on the google I got some hint that we have to run the code on "OTA Provisioning option ".
Now I don't know how to do that. I have "Version 2.5.2 for CLDC" of WTK. Can anybody suggest me on that?
