Configuring JRE/JDK Paths

40 iPlanet Web Server, Enterprise Edition Programmer’s Guide to Servlets • May 2001

• JDK Runtime Classpath

The class path includes the paths to the directories and jar files needed to run

the servlet engine, the servlet examples, and any other paths needed by

servlets that you add. You can add new values to the existing class path, but

don’t delete the existing value since it includes paths that are essential for

servlet operation.

Supply values for the following fields if you select the JRE radio button:

•JRE Path

Enter the path for the JRE. This is the directory where you installed the JRE.

• JRE Runtime Libpath

Enter the runtime library path for the JRE.

It is easiest to use the Configure JRE/JDK Paths page to switch between the JRE

and the JDK, but you can also make the change programmatically, as follows:

•On Unix:

Edit the file server_root

/https-admserv/start-jvm.

If the server is currently using the JRE, this file has a variable

NSES_JRE. To

enable the server to use a JDK, add the variable

NSES_JDK whose value is the

JDK directory. You’ll also need to change the value of the

NSES_JRE variable.

NSES_JDK should point to the installation directory for the JDK, while

NSES_JRE should point to the JRE directory in the installation directory for JDK

(that is, jdk_dir

/jre).

• On Windows NT:

Add the path to the Java libraries to the

extrapath setting in magnus.conf.

Edit the

NSES_JDK and NSES_JRE variables in the registry

HKEY_LOCAL_MACHINE/SOFTWARE/Netscape/Enterprise/6.0/. If the server is

enabled to use the JDK, both these variables are needed. If the server is to use

the JRE, only the

NSES_JRE variable should be set.

NOTE If you are not sure of the JDK runtime libpath, the JDK runtime

classpath, or the JRE runtime libpath, leave these fields blank to tell

the server to use the default paths.
