Chapter 2, Installing iPlanet Web Server 23

Installing a Java Developer’s Kit

If you are planning to use Java, you must install a Java Runtime Environment

(JRE) or a Java Developer’s Kit (JDK). iPlanet Web Server includes a JRE that

you can install during the installation process. However, you may prefer to

install a JDK.

You need either a JRE or a JDK to use the following features:

• Java servlets

• server-side JavaScript database connectivity (LiveWire)

Warning If you are using HP-UX, you must install the JRE included with iPlanet Web

Server or supply a JDK. Without one or the other, the HP-UX iPlanet Web

Server won’t run.

You need a JDK to run the following feature (it will not run with a JRE):

• Java Server Pages (JSPs)

Because you need a JDK to use JSPs, JSPs are only turned on by default if you

provide a path to a JDK during installation.

Different platforms require different versions of the JDK:
