Sun OpenSSO Enterprise Policy Agent 3.0 Guide for Apache HTTP Server 2.0.x

Setting Your JAVA_HOME Environment Variable

The agent installation program requires the Java Runtime Environment (JRE) 1.5 or later. Before you install the agent , set your JAVA_HOME environment variable to point to the JDK installation directory for the JDK version you are using. If you have not set this variable (or if you set it incorrectly), the program will prompt you for the correct path.
