[Tinyos-help] Problems with javacomm

[Fabrizio Stefani]

OK, I solved reinstalling java as explained in 
https://jdk-distros.dev.java.net/ubuntu-dev.html
and then repeating the steps "Compile Java Tools", "TOSCOmm" and "JNI" 
in http://www.chadmetcalf.com/tinyos-1x-on-ubuntu/

Now java programs work properly with a tmote attached to the 
/dev/ttysUSB0 virtual com port.
