Hi, I had a similar problem because I did not have permission for reading javax.comm.properties file but I was using UBUNTU Operative System, so I guess in Windows should not be a problem.
Do you have javax.comm installed in your computer?If you do, do you have javax.comm.properties in the right place?

I have tried to copy both toscomm.dll and getenv.dll from my TinyOS (under Cygwin) installation to the working directory (where my app is running) but I still get the following error: java.io.IOException: Could not open COM1: TOSComm JNI library runtime error: Error 5. Acces denied. in NativeSerialPort.CreateFile at net.tinyos.packet.SerialByteSource.openStreams(SerialByteSource.java:58) at net.tinyos.packet.StreamByteSource.open(StreamByteSource.java:51) at net.tinyos.packet.Packetizer.openSource(Packetizer.java:139) at net.tinyos.packet.AbstractSource.open(AbstractSource.java:69) at net.tinyos.packet.Packetizer.open(Packetizer.java:132) at Localization.WSNLocalizatorImpl.executeInputParser(WSNLocalizatorImpl.java:4 6) at Localization.WSNLocalizatorTest.main(WSNLocalizatorTest.java:43) stream:error (text) Any ideas?
