Java Plug-In

Regardless of the browser you are using (see supported browsers), the first time your browser attempts to load the LifeKeeper GUI, it will either automatically download the Java Plug-In software or redirect you to a web page to download and install it.  From that point forward, the browser will automatically invoke the Java Plug-in software every time it comes across web pages that support the technology.

Downloading the Java Plug-in

Java Plug-in software is included as part of the Java Runtime Environment (JRE) for Solaris, Linux and Windows.  Downloading the JRE typically takes a total of three to ten minutes, depending on your network and system configuration size. The download web page provides more documentation and installation instructions for the JRE and Java Plug-in software.

Note 1: You should close and restart your browser after installing the plug-in and whenever plug-in properties are changed.

Note 2: Only Java Plug-in version 1.3.x or later are supported with LifeKeeper.

Java Plug-in Troubleshooting

If you are using Netscape 6/7, Mozilla 1.x or Firefox 1.x, you may need to create a symbolic link in the Netscape, Mozilla or Firefox plugins directory to the path of the file under the $JAVAHOME directory.

For example (Firefox 1.5 and jre 1.5):

cd /usr/lib/mozilla//plugins 
ln -s/usr/java/jre1.5.0_07/plugin/i386/ns7/

For Netscape 4, if your browser doesn’t find the Java Plug-in even though you’ve installed the Java Runtime Environment, including the Java Plug-in, be sure that the NPX_PLUGIN_PATH environment variable is set to the location of the Java Plug-in (the directory in which the file is located) e.g. export NPX_PLUGIN_PATH=$JAVAHOME/jre/plugin/i386/ns4 where $JAVAHOME is the top-level directory of your Java Runtime Environment installation.

The Java Plug-in supports the Java 2 SDK, Standard Edition v1.3 security model. All applets are run under the standard applet security manager. See the Java Security FAQ or Setting Browser Security Parameters for the GUI Applet for more information.  

In some platform/browser combinations, the Java Plug-in software will affect the appearance and behavior of Java components in the LifeKeeper GUI such as the ScrollBar, ToolBar or Menu components. In many of these situations, if you resize or iconify/de-iconify the window (i.e. force a repaint) as a workaround, the problem will go away.
