Primarily these packages were meant to learn the language. They may be read as examples of what can be done with the various API coming with the JDK. But they were also designed to provide basic functionnalities for real life applications.

The org is one of the Top Level Package. The others TLP contain applications developped within this framework. Under org 4 packages are found :

• ariane which in turn is divided in about 10 final packages. This set contains the basic utilities used in the demos and applications. It is the continuation of the work done on the Ariane environment since 1990.

• demo which consists of a bunch of small applications meant to test the ariane packages.

• benchmark contains programs to get a idea of performances realized with Java. Currently there is one program comparing Java and C++ for numerical calculations.

• oodb which is devoted to the object-oriented database systems. The main subpackages are bdms containing the classes of the Bridged Databases Management System and bdnet containing the Corba version of this BDMS.

The hep is another Top Level Package. It is meant to contain applications for the High Energy Physics experiments.

The JVS offers also a set of html pages proposing a selected documentation about the Java computing.
