Setting Up the Java Environment

Tomcat requires a Java Runtime Environment (JRE) from J2SE version 6 or later.

To install and set up a JRE on the target machine:

1.	Download the Java 2 Standard Edition JRE 6, from http://www.oracle.com/technetwork/java/javase/downloads/index.html.

2.	Install the JRE on the target machine according to the instructions in the download package.

3.	Set an environment variable named jre_home to the directory into which you installed the JRE. The default installation locations are:

•	(Windows users) C:\Program Files\Java\<JRE_version>, for example

•	(Linux users) <JRE_version> in the directory where the JRE self-extracting binary was run.

4.	Append jre_home/bin to the path environment variable.

Note: You can use the full Java Development Kit (JDK) rather than just the JRE. In this case, set the java_home environment variable (not jre_home) to the directory into which you installed the JDK, and append java_home/bin to the path environment variable.
