This chapter includes the following information:
Java Plug-in 1.2 is included in the Solaris 8 base package CD and automatically installs with Solaris 8.
Java Plug-in installs in the /usr/dt/appconfig/netscape directory by default, allowing for easy mass deployment. Since you can install Java Plug-in 1.2 in a central location, all your users can access the plug-in over NFS. This installation method creates a single point of administration and makes it easy to perform future upgrades.

Perform the following tasks to verify that the installation was successful.

In Navigator, type file:/usr/dt/appconfig/netscape/j2pi/ControlPanel.html in the Netsite field to open the Control Panel. The Control Panel is an applet that uses JPI. Therefore, if the Control Panel opens, the plug-in is successfully installed.
With multi-user systems, you set environment variables in each user's environment in one of the following locations:
At the command line
In a .cshrc file
In a .profile file
You installed Java Plug-in in a location other than the default installation directory (/usr/dt/appconfig/netscape).
You installed both Java Plug-in 1.2 and 1.1.2 on your system and want to specify which plug-in to use.
You want to use a JRE other than 1.2.1_03.
You want to view Java Plug-in tracing information (see "Displaying Java Plug-in Tracing Output").
You use the NPX_PLUGIN_PATH environment variable to specify a non-default location of Java Plug-in, or, if you installed both Java Plug-in 1.2 and 1.1.2 on your system, to specify the plug-in you want to use.
If you install a plug-in in the same location as Netscape Communicator, Netscape defaults to that plug-in.
|csh||% setenv NPX_PLUGIN_PATH [path to plug-in]:$NPX_PLUGIN_PATH|
|sh or ksh||% NPX_PLUGIN_PATH=[path to plug-in]:$NPX_PLUGIN_PATH|
|% export NPX_PLUGIN_PATH|
You must include the directory of the plug-in you want to use as the first directory in the plug-in path.
You use the NPX_JRE_PATH environment variable to specify the use of a non-default JRE with Java Plug-in.
Sun does not support the use of any JRE less than 1.2.1_03 with Java Plug-in 1.2.
|csh||% setenv NPX_JRE_PATH [new JRE location]|
|sh or ksh||% NPX_JRE_PATH [new JRE location]|
|% export NPX_JRE_PATH|
After you uninstall Java Plug-in, you must unset any environment variables. In addition, if you modified any settings using the Java Plug-in Control Panel, you must delete the ~/.java/properties file.
Type su at the prompt to become superuser.
Enter the superuser password at the prompt.
Type prodreg to open the Prodreg Utility window.
Select Java Plug-in 1.2 and click Remove.
Click Exit to close the Prodreg Utility window.
If you previously set any environment variables, type the appropriate commands shown in the following table to unset the environment variables.Table 2-4 Unsetting Environment Variables
|To unset...||Using||Type this command|
|Java Plug-in path||csh||% unsetenv NPX_PLUGIN_PATH|
|sh or ksh||% unset NPX_PLUGIN_PATH|
|JRE path||csh||% unsetenv NPX_JRE_PATH|
|sh or ksh||% unset NPX_JRE_PATH|
