Java Code for Serial Port RXTX

balaqemu · 11-03-2011, 12:46 PM

Hi,

I have installed the RXTX jars(http://rxtx.qbang.org/wiki/index.php/Main_Page) but I get the import error

TwoWaySerialComm.java:1: cannot find symbol
symbol : class CommPort
location: package gnu.io
import gnu.io.CommPort;

I followed all the steps provided by that link . I'm trying on Ubuntu JVM -> ie /usr/lib/JVM/java-1.5.0-sun-1.5.0.26 .

pls help

It`s look like your JVM does not know where the RXTXcomm.jar locates. Are you sure that you defined the CLASSPATH correctly?
Try make project with IDE(Eclipse, NetBeans, ...) and connect all necessary *.jar and *.so files for your project.
I think this way will solve your problem.
