I am new to Java , and trying to write a serial communication application.
I am using Windows 7 (32 bit)
D:\Glaswegian\Java\RXTX\Test>java -version

I downloaded the RxTx
http://henrypoon.wordpress.com/2010/12/25/installing-rxtx-for-serial-communication-with-java/ http://rxtx.qbang.org/wiki/index.php/Using_RXTX
As mentioned in above link, unzipped rxtx-2.1-7-bins-r2. copied rxtxSerial.dll to C:\Program Files\Java\jre7\bin copied RXTXcomm.jar to C:\Program Files\Java\jre7\lib\ext
I am just trying to run this code:
import gnu.io.*;
public class RxTxComm{
public static void main(String[] args)
{}
}
I am getting below Error.

Referred this as well: javac -classpath not doing the trick
What is wrong?
I guess I copied to the wrong folder. I resolved this issue like this:
