java.lang.ExceptionInInitializerError while trying to load applet using RXTXcomm jar

I created an applet using RXTXComm.jar to read values from a COM port. When I run the applet in the Eclipse IDE as an applet, it's working. But when I run it through my application it's giving this error in the applet console:

java.lang.ExceptionInInitializerError thrown while loading gnu.io.RXTXCommDriver

What could be the problem?
