ELFCLASS64 error

I am trying to talk to a usb modem.
can anyone tell me what a ELFCLASS64 error is?

A quick search of the RXTX mailing list turns up this gem:

It looks like you have a 32 bit JRE installed. You need to match rxtx
with your JRE arch.

thank you
i solved it.
i had to put a i686 librxtxSerial.so driver
in my path so that fixed the problem.
