Ok.  I am feeling a little goofy right now.  I clicked on the links to download the files and was prompted to download (save) file ntnujavazip (1.27 MB).  I open the folder users_ntnu_fkh_  but there is not a caliper.jar file in this destination.  There is a folder called caliper_pkg.  This folder contains 5 CLASS files (caliper, caliperApplet, caliperSimulation, caliperview$1, and caliperview).  A file called caliper that is a XML document and a file called caliper_intro 1 which is a HTML document.  I do not see the .jar file.  Try not to laugh at me too much.  Thanks for prompt support.
