Updating Java for Linux

If you are running Linux, the Web (SSL) vpn@ucsf works with Netscape 7 and Mozilla 0.9.9.

What version of Java am I running?

Web Java Test

The OAAIS web site provides a quick test to verify the version of Java currently in use by your web browser. We recommend that you use this service before continuing with these instructions. http://its.ucsf.edu/information/network/vpn/test/

Sun Java Virtual Machine

To determine if your machine has the Sun Java Virtual Machine (JVM):

1. Launch your browser.
2. From the Help menu, select About Plug-ins.
3. Look for the Java plug-in icon. If you do not have the plug-in, then you need to install it.

Installing or Upgrading Java on Linux

To install applications on a Linux machine, you need to log in to your machine as root. Note that the SSL vpn@ucsf works with Netscape 7 and Mozilla 0.9.9. To install the Sun JVM, from the Sun site (http://java.sun.com/j2se/) download either the:

1. Linux RPM for RedHat or
2. GNUZIP/Tar (for other Linux platforms) for the JRE file

Note: Make sure that you download the GNUZIP/Tar script to the directory where you want to install the Java Plug-in, such as: /usr/local.

Run the downloaded executable or extract the archive per the instructions provided by Sun Microsystems.

Create a symbolic link from the browser’s plug-in directory to the installed Java library libjavaplugin_oji.so per the included readme.txt document.
