I am trying to use the 64 bit rxtx serial communication library (downloaded from cloudhopper) with 64bit windows 7 and eclipse. I get the message: java.lang.UnsatisfiedLinkError: no rxtxSerial in java.library.path. The dlls are in the /jre/lib dir as well as the Windows/System32. The RXTXcomm.jar is in the build path for eclipse as well as in the jre/lib/ext dir. I ran process monitor in the background and and see that RXTXcomm.jar, rxtxSerial.dll, and rxtxParallel.dll are all found and have been opened, So I am unclear as to why this problem is occurring.

Any suggestions.

Go to Project -> properties -> Java build path ->Find your .jar. Click on + to open the JAR's properties. Select Native library location and edit it to point to RXTX's shared library (.DLL, .so, .dylib).
