This is a one of those fantastic "features" of using Java for hardware access. Java has no idea what ports qualify as serial ports, and rather than let you specify at the command line a particular file, it will error out if it doesn't match it's own list of such things.
If you're using sun's java, what you need to modify is the javax.comm.properties file. This is in <javadir>/jre/lib/ext/ . You'll notice at the end it looks exactly like the error you're getting. Just add /dev/ttyUSB0 to the list, assuming there is such a device. It won't hurt to add ttyUSB1 etc as well, in case you wind up having more than one plugged in at a time.
