Setting Environment Variables

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

When to Set Environment Variables

You set environment variables for Java Plug-in in the following situations:

• 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").

Setting the Plug-in Path

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.

---

Note -

If you install a plug-in in the same location as Netscape Communicator, Netscape defaults to that plug-in.

Table 2-2 Setting the Plug-in Path

Shell	Command
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

---

Note -

You must include the directory of the plug-in you want to use as the first directory in the plug-in path.

---

Setting the Path of a Non-Default JRE

You use the NPX_JRE_PATH environment variable to specify the use of a non-default JRE with Java Plug-in.

---

Note -

Sun does not support the use of any JRE less than 1.2.1_03 with Java Plug-in 1.2.
