Installing Java for UCL Administrative Systems

Several web-based Administrative Systems at UCL require the use of an additional Java plug-in component to the browser in order to run.

This page outlines how to get Java, how UCL Admin Systems make use of it, and common problems that you may encounter.

Summary: May 2015

Windows Users: We recommend installing the latest update for Java 8 (Update 45 or higher).

Mac Users: There are issues with the latest updates to Java. The latest stable version for use with Admin Systems is Java 8 Update 31 - see note below.

FAMIS Users: the application is currently only certified for Java 7 update 17. While it should work with Java 8, you may need to downgrade if you experience problems.

Who needs to download?

There are two options available for using Java with UCL Administrative Systems:

Windows Users:

  • Install Java 8: Windows users may install Java 8 on their desktop PCs and run systems directly from their internet browsers. We recommend keeping auto updates enabled.

Mac Users:

  • Install Java 8 Update 31 from the list and older Java versions.
  • The version of Java supplied by Apple will not work as it does not include a web browser plug-in.
  • There are problems with later Java 8 updates (40 and higher) that cause Admin Systems to stop running. We recommend turning off auto-updating from the Java panel in System Preferences [as of May 2015].
  • IMPORTANT: installing older versions of Java and disabling auto-updating will increase risks to your computer. Only do this if you use Java exclusively for UCL Admin Systems. A safer option is to use the Desktop @ UCL service. See the section below on reducing risk when using Java applications.

Managed Services:

  • If you are using Desktop @ UCL, Java will already be installed and you need do nothing.
  • If you are running Administrative Systems from your own or a departmentally managed computer, you need to check first if you have Java installed - see below.

Alternative Methods:

  • If you are unable to install or run Java or the necessary browser plugins on your desktop computer or device, they can instead be accessed via Desktop @ UCL.
  • Using Java-based browser plugins can increase the risk that you computer can be compromised. To reduce this risk:

    • Use a separate browser to access Admin Systems. Allow the Java plugin to run in that browser and disable it in your other day-to-day browser. For tips on how to enable/disable plugins view your browser help.
    • Add UCL sites to Java Security Exceptions list (in the Java Control panel).

Java Versions for specific applications:

As of May 2015, ISD recommends that users install the latest update of Java 8. This will be compatible with all Oracle Java based applications used at UCL.

Exceptions:

Installation

If you do not have software installation privileges

Please ask your system administrator to install Java on your behalf - installing Java will require administrative rights to your computer.

If you have software installation privileges

Download and Install Java 8 from the Java website. Select the version most appropriate for your operating system, e.g.:

  • Windows x86 for Windows XP or Windows 7 or 8
  • Windows x64 for 64-bit versions of Windows (inc Windows 8)
  • Mac OS X x64 for Apple Macs - download from the Previous Versions page.

Uninstall Old Versions: We recommend that all older versions of Java are removed. Older versions of Java can make systems very insecure and vulnerable to being compromised.

Older Versions of Java

We recommend that you always use the latest version of Java. Installers for previous versions are available but should only be installed if advised by you support team.
