Hello
I am a student and i am working on a wireless video sensor network using
TelosB motes.
I am using cygwin and got most of TinyOS 2.1.1 working except for the java
GUI, the problem is i got the motes to blink and also communicate using the
quick start guide for the basestation and multihoposcilloscope programs but
i cannot get it to display on a graph in java GUI i keep getting error.
i have set up all my class paths and everything else but i really don't know
how to get java to work i am using jre7 and my class paths are:-
.;C:\Crossbow\cygwin\opt\tinyos-2.x\support\sdk\java;C:\Program
Files\Java\jdk1.7.0_03\bin;
Please help me i tried to find answers on the internet but with no luck.
Thanks in advance,
Mohamad.
The error code i get is...
