.2 Installing JDeveloper Base

For quicker download times, you can download the base installation (jdev<edition>base1111.zip). The base installation requires that you already have JDK 5.0 on your machine because the SDK is not included.

To install JDeveloper from jdev<edition>base1111.zip:

1. If you don't have JDK 5.0 installed, you can obtain it from: http://java.sun.com/javase/downloads/index_jdk5.jsp.
2. Unzip jdev<edition>base1111.zip to the target directory.
3. Set the variable SetJavaHome in the file <jdev_home>\jdev\bin\jdev.conf to the location of your SDK installation. Use an editor that recognizes UNIX end-of-line characters, such as WordPad. When you save the file, WordPad will warn you that it is about to save the file in text-only format. You can ignore this warning.

For example, in a Windows environment, if the location of your JDK 5.0 is in a directory called jdk1.5.0_06 on your D: drive, your entry in jdev.conf would look like:

SetJavaHome d:\jdk1.5.0_06
