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.
