The OpenSpirit Java API is supported on Windows, Linux and Solaris.  Your application may use Java 1.5 or 1.6 (though the next release wil require 1.6).

The OpenSpirit SDK comes with an example Java/ Swing application that illustrates the use of the Java API services. 

The Java API documentation may be found here (a 2.3 MByte zip file of the javadocs.)
