WARNING: It won't run on a Java Runtime Environment (JRE) alone. Java workalikes, including Blackdown, Kaffe, and others do NOT run OFBiz successfully (yet), but you can use OpenJDK for recent versions (at least Java 8).

Sun's Java version numbering is was a bit schizophrenic-- Java 6 means version 1.6, while Java 5 means version 1.5. From Java 8 Oracle only labelled this way. OFBiz Java version requirements are as follows:

...

• Version 50.0 = Java 1.6.x
• Version 49.0 = Java 1.5.x
• Version 48.0 = Java 1.4.x

You can get the latest Sun Oracle Java SDK here: http://javawww.sunoracle.com/technetwork/java/javase/downloads/index.jsphtml

If Java is already installed on your target machine, make sure it is the full JDK and appropriate running version 6 (Build 1.6.*). You can check this by typing "java -version" (you may also check javac -version) at a command prompt.
