I am not sure what you mean by "put my applet into the package sf", but
you probably should not do that.
At the beginning, you'll have to import the packages that you will need.
E.g.:
import net.tinyos.comm.*;
import net.tinyos.packet.*;
...
Then you will have to replace the whole networking stuff (this will be
done by the TinyOS libraries).
The first line in the code below defines the access string to the serial
forwarder (check the mote-pc communications tutorial for details). The
second line creates a PhoenixSource (not sure what it is exactly, but I
think it is a low-level communication object that will then communicate
with the serial forwarder). The third line will then create the actual
mote interface where you will be able to register the appropriate
listener for your packet format.
If you haven't implemented a standalone application, I strongly suggest
that you do this first and then port this application later to an
applet. It is much easier to debug a standalone application, plus you
get step-by-step instructions from the TinyOS tutorials (really, read
the mote-pc communications chapter!) and sample code.
Cheers,
