Prior to installation ensure that the latest stable Eclipse version (available at the release date of Oxygen XML Developer plugin ) is installed on your computer. The current Eclipse version number is 3.7.
Oxygen XML Developer plugin supports only official and stable Java virtual machine versions 1.6.0 and later from Sun/Oracle (available at http://www.oracle.com/technetwork/java/javase/downloads/index.html) and from Apple Computer. The Java Virtual Machine from Apple is pre-installed on Mac OS X computers. For Mac OS X, Java Virtual Machine updates are available at the Apple website. Oxygen XML Developer plugin may work very well with JVM implementations from other vendors but the eventual incompatibilities will not be solved in further Oxygen XML Developer plugin releases. Oxygen XML Developer plugin does not work with the GNU libgcj Java virtual machine.
