Hi Ngoc Thanh, In order for Java to access the serial port (and some system information), an extension to Java is needed. This extension is provided by TinyOS in the form of two libraries: toscomm.dll and getenv.dll. The error that you are seeing when trying to execute the TestSerial program means that these libraries were somehow not properly installed (the TinyOS installation procedure has some problems there).
To fix this, you can manually copy these two libraries into the jre/bin folder (if they are called toscomm-32.dll and getenv-32.dll, you'll have to rename them). If this doesn't work, you can download a test program and execute it (if double-clicking on the program won't start it you can execute it with the command "java -jar tosruntime.jar"). The program should tell you all sorts of diagnostic information about your Java installation and you can copy/paste this information into an e-mail which helps us understand what is not working with your installation. http://www.schlangenstein.ch/tosruntime.jar Cheers, Urs On 10/17/10 5:54 AM, [email protected] wrote: > Dear Tiny-OS help member, > > > > I've got a big trouble when I try to run TestSerial example of tinyos-2.x. > > It has bug as : > > " > > $java TestSerial > > Getenv JNI library not found.
