Installing a Java Developer’s Kit
Chapter 1 Before You Install iPlanet Web Server, Enterprise Edition 21
Installing a Java Developer’s Kit
If you are planning to use JSPs that have not been compiled, you must install a Java
Developer’s Kit (JDK), also referred to as a Java 2 Software Development Kit (SDK).
Servlets and precompiled JSPs require only the JRE that comes with iPlanet Web Server.
Different platforms require different versions of the JDK. See “Hardware and Software
Requirements,” on page 12 for specific version numbers.
Download the JDK in the following locations:
•Sun Solaris:
http://java.sun.com/products/j2se/
• HP-UX:
http://www.hp.com/go/java
• IBM AIX:
http://www.ibm.com/java/jdk/download/index.html
• Compaq Tru64:
http://www.compaq.com/java
• Windows NT:
http://java.sun.com/products/j2se/
• Linux:
http://www.blackdown.org
You can install the JDK before you install iPlanet Web Server, and provide the path to it
during installation, or you can wait until after you’ve installed iPlanet Web Server to install
it.
After installation, you can change the JRE or JDK iPlanet Web Server uses. In the
Administration Server, on the Global Settings tab, use the Configure JRE/JDK Paths page.
You can also change the path to the JRE/JDK in this page.
CAUTION
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.
