JDK

OFBiz is written in Java and requires the full Sun Java Development Kit (JDK) to run. It won't run on a Java Runtime Environment (JRE) alone. Java workalikes, including Blackdown, Kaffe, and others do NOT run OFBiz successfully (yet).

Java version numbering is schizophrenic-- Java 6 means version 1.6, while Java 5 means version 1.5. Java version 1.5 is required for OFBiz release 9.04, while java version 1.6 is required for the OFBiz trunk.

...

If Java is already installed on your target machine, make sure it is the full JDK and running version 6 (Build 1.6.*). You can chck this by typing "java -version" at a command prompt.Java workalikes, including Blackdown, Kaffe, and others do NOT run OFBiz successfully (yet).

Operating system

OFBiz will run on any operating system that supports a Sun Java SDK. Microsoft Windows (XP and newer), Apple Macintosh (OS X and newer), Linux (most recent distributions), and Unix (FreeBSD, OpenBSD, NetBSD) are all supported.

OFBiz can operate for evaluation and testing purposes on a minimal server. Current trunk installs take about 560MB of disk space. We have operated OFBiz on a 700MHz Celeron and with 512MB of RAM running Debian Linux. Production servers will probably want more up-to-date hardware commensurate with the expected load.

Database

OFBiz comes with an IBM Derby SQL database built in. This is usually fine for evaluation, development and testing. Production servers will probably want a more powerful database. A variety of databases are supported, including PostgreSQL, MySQL, Oracle, Microsoft SQL Server, and others.
