Java Applets on WebAssign
The Java applets on WebAssign are adapted from the Java PADs created by Scott Bonham at Western Kentucky University. They use a relatively old technology, based on Java version 1.1, which, in principle, should work on almost any system. This is evidently not true, since there have been reports of students not able to use the applets on their computers.
If the Java applets are not working for you, try the following options:
- First, make sure that you have a current Java runtime installed on your computer, including the add-ons that will allow it to run under a browser. The latest Java runtime can be downloaded from Sun Microsystems at www.java.com. After you download and install Java, you may need to restart your computer, and reload the webpage containing the applet.
- You may still discover that the applet does not work properly.
This can happen if the browser or operating system does not recognize
the version of Java that WebAssign delivers. The applets are believed
to work on the following systems with the latest version of Java:
- Windows XP Professional, Service Pack 3, with Firefox 2.0 and higher.
- Windows XP Professional, Service Pack 3, with Internet Explorer versions 6.0 and higher
- Windows 7 with current versions of Firefox or Internet Explorer. (These are the computers in the Physics Study Center and B101 computer lab.)
- Mac OSX 10.4 and higher with Firefox 3.0 and higher.
- Linux (Red Hat 9, Suse 8.2, and equivalent or higher) with Firefox 3.0 or higher.
- There are known problems with the Opera and Safari browsers on a Mac. Download Firefox and try that.
- On Windows with Firefox there is an annoyance: the window with the Java applet immediately hides under the main browser after the web page has loaded completely. It is still there, and will work fine when you bring it to the front again.
- Finally, if you cannot get Java to work on your usual computer, use the computers in B101 in the physics building, or the physics study center in the basement of the A wing, or the computers (both Windows or Mac versions) in Mary Gates Hall. These have been personally tested by the lab instructor and found to work.
