Hi Michael & Others too ..

Continuing with the same problem ..  today one (very simple) idea came to my
mind ..
As i want to run a java application  (Serial Forwarder) though another java
app (my application)  why m i using all stuff like runtime , cygwin n all..
I could simply call main method of serial forwarder like this ..

String[] args = {"-comm","-ser...@com16:telosb"};
try{
net.tinyos.sf.SerialForwarder sff = new net.tinyos.sf.SerialFrowarder(args);
}catch(...){
..
}

i was hoping this should run ..  but i got this error  message..  (actually
..  sf window pop up for few milliseconds and all application crashed with
this error. )
/**********************************************************/
The toscomm JNI library was not found.
Check that your tinyos-tools package is installed and try
rerunning tos-install-jni.
Aborting.
/**********************************************************/

this error i did not encountered previously ..
i tried this ..  but ..
/**********************************************************/
$ tos-install-jni
Installing 32-bit Java JNI code in /cygdrive/d/Program
Files/Java/jdk1.6.0_14/jr
e/bin ...
install: cannot stat `/usr/lib/tinyos/*-32.dll': No such file or directory
/**********************************************************/


m i again mistaking with CLASSPATH , PATH or anything else ?

Thanks  a lot for your help ..
