[Rxtx] : Error RXTXCommDriver

[Indtiny s]

Hi,

I have downloaded and placed  the following files

 RXTXComm.jar -> /usr/lib/jvm/java-6-openjdk/jre/ext/RXTXcommjar
librxtxSerial.so ->
/usr/lib/jvm/java-6-openjdk/jre/lib/i386/librxtxSerial.so .

But I'm  able to compile the simple code but I cant run, when I run
the code I get the following error

ERROR: java.lang.UnsatisfiedLinkError: no rxtxSerial in java.library.path
thrown while loading gnu.io.RXTXCommDriver

though  I have placed this  javax.comm.properties to the jre/ext/


..
