[Tinyos-help] Compile Error

[Anuradha Eragani]

The NullPointerException was occurring due some plugin path not being set
and some plugins.list file not being available. But this exception got fixed
when I compiled all the files in opt\tinyos-1.x\tools\java\net\tinyos\sim
folder which generated simdriver.jar file (this file wasn't there before).
This jar file contained plugins.list file and hence the exception got
cleared.

 

However, I'm facing a different problem now. When I'm trying to run the
application in the simulator, I'm encountering the following error message:

Welcome to Tython. Type 'quit' to exit.

ESC on a line by itself will pause/resume the simulator.

Any idea why this is happening?? Was I supposed to explicitly compile the
files in sim folder to generate the simdriver.jar file?

 

Thanks
