Whether you are using Netscape (Navigator 4.05 and later) or Internet Explorer (4.01 and later), 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 supports the technology.
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: Earlier versions of Java Plug-in software (e.g. Java Plug-in 1.1.x or 1.2.x) and Java Plug-in 1.3.x software cannot co-exist on the same system. When upgrading Java Plug-in software, it is recommend that users uninstall Java Plug-in 1.1.x or 1.2.x software before installing Java Plug-in 1.3.x software. Installing Java Plug-in 1.1.x or 1.2.x software after installing Java Plug-in 1.3.x software on the same system is not recommended.
In order to use the control panel, you need to enable Javascript in your browser.
To open the Java Plug-In Control Panel on a Windows system, point to Programs and then click Java Plug-In Control Panel.
To open the Java Plug-In Control Panel on a Linux system, run <your home account>/.netscape/java/ControlPanel. (Note that in later versions of the Java Plug-in for Unix, the Java Plug-in Control Panel may be installed at the system level.)
If you are using Netscape 6/7 or Mozilla 1.x, you may need to create a symbolic link in the Netscape or Mozilla plugins directory to the path of the libjavaplugin_oji.so file under the $JAVAHOME directory.
For example:
cd ${NETSCAPE6}/plugins
ln -s ${JAVAHOME}jre/plugin/i386/ns610-gcc32/libjavaplugin_oji.so
For Netscape 4, if your browser doesn’t find the Java Plug-in even though you’ve installed the Java Runtime Environment, including the Java Plug-in, be sure that the NPX_PLUGIN_PATH environment variable is set to the location of the Java Plug-in (the directory in which the javaplugin.so file is located) e.g. export NPX_PLUGIN_PATH=$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 http://java.sun.com/sfaq 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.
