[Tinyos-help] Unable to use java in matlab

[Stephen Chou]

I add two line in matlab classpath.txt file as

C:\Program Files\cygwin\opt\tinyos-1.x\tools\java\
C:\Program Files\cygwin\opt\tinyos-1.x\tools\java\comm.jar

but when I perform "methods net.tinyos.sf.SerialForwarder" in matlab,
the output is "No methods for class net.tinyos.sf.SerialForwarder or
no class net.tinyos.sf.SerialForwarder." how can I deal with it?
Thanks
