OFBiz is written in Java and requires a full Java Development Kit (JDK) from Sun/Oracle or OpenJDK to run.

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).

Sun's Java version numbering is a bit schizophrenic-- Java 6 means version 1.6, while Java 5 means version 1.5. OFBiz Java version requirements are as follows:

• trunk, 13.07 requires Java SDK version 1.7
• 12.04: requires Java SDK version 1.6 or OpenJDK 7
• 11.04, 10.04: requires Java SDK version 1.6
• 9.04: requires Java SDK version 1.5 (or greater)

Also if you get this kind of error "class file has wrong version 50.0, should be 49.0", below are a list of some of the version numbers and their corresponding Java runtimes:

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