I have tried to run the High Frequency Program from the xbow/apps folder and i get the following error:

I am currently running this program on 2 Mica2 motes. I have installed TOSBase on one and the program on the other. When i run the command "java Sample 200 20000", i get the error as above. I have opened Serial Forwarder as instructed by the readme file. The error is that it can't find a platform specific version of TOSMsg. Could anyone tell me how to resolve this error?
Thank you and regards.

I'm not sure MicaHWVerify works with the 'Z's I haven't tried it.
If you are getting radio comm from other programs you don't need
to try it either. Have not actually used the HFS program but the
mica systems are very similar so I would expect it to work ok.
One thing to try with your '2's...if you are not compiling under
contrib/xbow, do it. The radio parameter settings under the 'normal'
app tree are not very good vis mica2.
