error with finding files
Hi,
I followed the linux installation of the rxtx libraries, and placed the librxtxSerial.so and the RXTXcomm.jar in the right directories.
I have set the CLASSPATH, the JAVA_HOME and the LD_LIBRARY_PATH directories ok.
but when I run the following application, I seem to not find the right library. is there any reason for this?
thanks, John
