Hi, I do not know the encryption-functionality, but regarding the serial communication, have you tried to check what the Java program is transmitting? Try to connect it to serial terminal in another computer. Also, you may try to implement a minimal serial-to-serial communication program so everything that the Java writes is gets to the mote, and this transmit it back to the computer.
Good luck!
