Java

Some features in WebLearn require your browser to be configured to use a supported Java plugin.

The Java plug-ins are part of the Sun Microsystems™ Java Runtime Environment (JRE) installation packages, which can be downloaded from http://www.java.com.

WebLearn supports the following JRE versions:

• Sun 1.4.2 (1.4.2_06 minimum)
• Sun 1.4.3
• Sun 1.5.x (excluding 1.5.0_02)
• Sun 1.6.x
• IBM 1.4.x
• Apple 1.3.x
• Apple 1.4.x

If you are using a University computer that does not pass WebLearn's browser check test for Java please contact the Service Desk and log a new call/incident:

• Student Service Desk
• Staff Service Desk

If you are outside of the University and would like to download and install a supported version of Java please visit the Sun Java website.

If you are using a non-University computer there are instructions on the Blackboard website for dealing with an incompatible version of Sun JRE or having multiple versions of Sun JREs installed.
