[Tinyos-help] High Frequency Sampling class path errors

[Chris Byers]

The attached is a print screen of an error I am getting when running the
HFS program.  This error occurs when I run the command java Sample 200
20000 per the HFS README.  Can anyone tell me how I may resolve this
error?

Thanks,

Chris

I haven't actually run the thing live,
but I'd assume you need something like this:

     export CLASSPATH=".;$TOSROOT/tools/java/classes"
