Hi, I have been searching all over the internet on how to communicate with the black berry through the USB cable. I want to write a Client application for the blackbery to send text messages to another device, how can I accomplish this? What java library will allow the black berry to perform general usb-serial communication through the usb cable?

Thanks for any help.

This can be done via the Connector class. There is a USB sample called "UsbDemo" provided with the JDE.

At a high level:

private static final String CHANNEL = "RIM_USBClient";
_sc = (StreamConnection)Connector.open("comm:USB;channel =" + CHANNEL);

_dis = _sc.openDataInputStream();
_dos = _sc.openDataOutputStream();

Do all java enabled cell phones have serial or usb communication via a serial cable? Or what is the standard physical communication protocol that all cell phones use, for example BB uses usb cable.

I believe http is the only communication method required for J2ME. IOW, I wouldn't count on a J2ME phone having serial or USB support.
