About Java and JavaScript


Java Notice:

Applets written in JavaScript work fine, but applets written in Java are no longer supported by browsers.

You can read more about the issue at Java.com

 

Troubleshooting

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.

Refresh Webpage

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).

Enable JavaScript

You no longer can unblock Java for specific pages. The applets written in JavaScript will work, but the older Java applets will not.

A useful website to detect Java on your browser is: http://www.javatester.org.

Downloads

Adobe Reader

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.

Web Browser

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.

About JavaScript

JavaScript is a language used to create dynamic webpage applications. JavaScript does not allow a program to access the files or directories on a user’s computer. Despite its name, JavaScript (originally called “LiveScript”) originated independently of Java and may not always be compatible with every browser.

The WISE site implements JavaScripting to allow real-time demonstrations of statistical concepts that are beneficial to the understanding of statistics. To use many features of this site, it is necessary to have a web browser that supports JavaScript such as Microsoft Internet Explorer (PCs) or Safari (Apples). JavaScript must be enabled on the browser.

Many of our earlier applets were written in Java. The loss of Java has dealt a serious blow to the WISE site. We have replaced some of the earlier applets with JavaScripting, but some of the tutorials that use Java applets have not yet been replaced.
