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: SIM:

Exiting on SIGINT at 0:0:4.62779925. Any idea why this is happening?? Was I supposed to
explicitly compile the files in sim folder to generate the simdriver.jar file? Thanks Anu |
