3.2. Java Environments Supported By JBoss Enterprise Application Platform 6
JBoss Enterprise Application Platform 6 requires Java 6 or Java 7. The list of supported Java environments can be found at http://www.jboss.com/products/platforms/application/supportedconfigurations/. A Java Development Kit (JDK) is required for development, and a Java Runtime Environment (JRE) is required to run JBoss Enterprise Application Platform.
Note
If you are using a RPM installation, you need a Java 6 JDK installed even if you use the Java 7 JDK for development.
