I'm writing a java application which has to communicate with has to communicate with an XBee radio over a usb-cable.To do this , I use the xbee-java API (http://code.google.com/p/xbee-api/)
On my old 32-bit machine it all worked fine . But when I imported the project to a 64-bit machine , it throws immediately an exception which says :" Can't load IA 32-bit .dll on a AMD 64-bit platform" . I don't have any idea how I can solve this problem .
the error code :
java.lang.UnsatisfiedLinkError: C:\Users\Tom\Documents\XbeeJava\rxtxSerial.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform thrown while loading gnu.io.RXTXCommDriver
Closing connection with local XBee

Thanks , Tom
It is not possible to load a 32-bit DLL into a 64-bit process.
Based on the description, the JVM you are running is 64-bit but the DLL rxtxSerial.dll
is 32-bit. To resolve, either:
rxtxSerial.dll
, orrxtxSerial.dll
