With recent Java updates, your security settings might block our Java applets from running. The WISE site is optimized for Internet Explorer – if a plugin is not supported by another browser, we suggest you use Internet Explorer.
If access to a WISE Java applet is blocked, you can take the following steps to unblock all of our Java applets:
- Go to the Java Control Panel
- In Windows: Click Start and type Configure Java in Search programs and files
- In Mac OS X: Click the Apple menu, click on System Preferences and then click on the Java icon
- Click the Security tab
- Click Edit Site List
- Click Add
- Type http://wise1.cgu.edu
- Click Add again
- Click Continue and OK
- Restart your computer
You can read more about the issue at Java.com
Viewing PDF files
If you have trouble viewing an Exercise file or other document downloaded as a PDF (Portable Document File) file, you may need to download and install Adobe Reader to view it.
If an applet does not behave or appear correctly, click the RELOAD/REFRESH button, usually signified by an arrow or arrows on your browser (or press F5 on your keyboard if you are using Internet Explorer).
If you receive a security warning that blocks Java, you can unblock Java for the WISE pages by following steps described under Java Notice on this page.

For more information on enabling Java, consult Sun Microsystem’s Java website. If neither refreshing the webpage nor enabling Java results in the webpage or applet being properly displayed, you may need to download and install the free Java Runtime Environment.
A useful website to detect Java on your browser is: http://www.javatester.org.
Adobe Reader is a free software program used to view PDF (Portable Document Format) files. Most WISE Exercise pages are downloadable and viewable in this format.
If enabling Java on your browser does not resolve problems accessing WISE applets, download and install the free Java software, Java Runtime Environment (JRE). Once you have downloaded and installed JRE, be sure that Java is enabled on your browser using the steps given in the Troubleshooting section.
If WISE web pages do not load, try upgrading to the latest versions of one of these web browsers. These software programs are free.
|Microsoft Internet Explorer (IE) is available for free download, and comes installed on Windows machines.|
|Mozilla Firefox, an open-source web browser, is available for Windows, Mac OS X and Linux.|
|Chrome is Google’s open-source browser, available for Windows, Mac OS X, and Linux. Chrome does not support Java applets.|
|Safari is Apple’s browser included with both Mac OS X and iOS. It is available for Windows as well.|
A Java applet is an application designed to run within a web page. Applets can operate across different computer operating systems because they rely upon a Java Runtime Environment (JRE) implemented by a specific computer’s web-browsing application.
Java Applets are secure and safe to use. One should always be wary of downloading applications from anonymous sources on the Internet because of the possibility of viruses. However, the Java language explicitly puts limits on the functionality of applets so as to prohibit malicious behavior. A Java applet cannot read or write from a user’s computer without permission from the user.
