The Furi java version only comes with those two files. Here is an excerpt from the readme file that tells how to run Furi for java:

Remember FURI needs
Java JDK 1.2.2, or JDK 1.1.7 and Swing 1.1.1.

Type the following to invoke FURI.

java furi.f

For JDK 1.2 and up, you can alternatively start FURI by:

java -jar furi.jar

I use the latter method. The java jdk can be downloaded for free from Sun, http://www.sun.com. After running Furi for the first time other files will be created, check other messages on this board for how to configure for hosts that will connect.
