WebCT Java Issue

The current version of WebCT – WebCT CE6 requires a specific version of Java 2 Runtime Environment (JRE) version installed in order for your web browser to work properly with WebCT. In addition, you must have ONLY ONE version of Java on your computer. Your browser will pass the Browser Check if you have more than one version or have an unsupported newer version installed. But you will still have difficulties when using WebCT. The auto update feature of Java usually installs the newest update and it causes problems. We strongly recommend that you check your computer to make sure you only have the supported version of Java installed and also turn off the auto update option. Please see below the instructions on how to remove unsupported versions of Java, install the supported one and disable the auto update feature.

Supported version of Java:

  • JRE 1.5 update 6 (this is the current version recommended by WebCT for use with WebCT 6)
  • JRE 1.5 update 8 (this is the most current version UTD has successfully tested with WebCT 6)

Please note the latest JRE 1.6 or JRE 1.5 update 9 or 10 are incompatible with WebCT 6.

Identify the Java version:

  • Go to Task Bar, double click the Java icon to view the version information

Check if you have multiple versions of Java and remove the incompatible versions:

  • Go to Start menu>>>Control Panel>>>Add/Remove Programs
  • Check for all programs that has a name beginning with ‘Java” or J2SE
  • Select and remove any unsupported version of Java

Download and install the supported version of Java:

  • Go to the following url: http://java.sun.com/products/archive/j2se/5.0_06/index.html
  • Click “Download JRE” link (second link)
  • Click to select “Accept License Agreement”
  • Click “Windows Online Installation, Multi-language”
  • Choose Run and follow the installation wizard to install (or Save the file on your desktop and double click to open it and go through the installation wizard)
  • Restart your computer

Disable the auto update feature of JRE

  • Go to window Task Bar and right click the Java icon>>>Open Control Panel>>>Update tab
  • Deselect the check box for “Check for Updates Automatically”
  • Click “Ok”
