arduino eclipse and serial communication

i use eclipse to programm to arduino.I had to reinstall the whole package these days.

I installed the tm plugin for terminal and rxtx also.

when i try to connect to the serial port i get error that another unknown program uses the serial communication.Do you know how to solve this?

This sounds like a question that should be asked on the Eclipse forums.

Verify that the serial port you're trying to use is indeed the Arduino's serial port.

Find that unknown program that has opened the Arduino's serial port, and stop it.
