Hi,
If I understand you correctly, you want to use the native libraries
without the TinyOS Java classes. In that case you need to explicitly
load the native libraries. In the TinyOS Java classes this is done in
net.tinyos.comm.TOSCommLibraryLoader.java with the instruction
System.loadLibrary("toscomm");
Alternatively, you can also use the method System.load(...), where you
can specify the full path and file name of the native library (in case
you want to install the native library to a different location).
You can find more details about JNI (the Java native interface) in this
e-book:
http://java.sun.com/docs/books/jni/
Cheers,
Urs
