Hy, I had the same problem when integrating the RXTXcomm into Netbeans under Ubuntu 11.10. I am guessing that you are not copying the files in the right place, at least that was my problem.

Under Ubuntu java is installed under usr/lib/jvm. BUT here I had a lot of forders (ex java-7-openjdk-i386, java-7-common, java-6-openjdk ...). In Netbeans I check what is the path of the JDK included into the project, it was java-7-openjdk-i386 . so I took the rxtxSerial.so (under windows it is rxtxSerial.dll) and copied it to java-7-openjdk-i386/jre/bin and it worked like a charm .

I hope this helps.
