The freeware Javelin modeler is a free, never expiring, full featured edition of Javelin without the code generation and management facilities. It is perfect for analysts, developers, educators etc., who want to perform object modeling and be able to document and print out their designs in the form of class diagrams and API references. It even supports importing of existing source code so you can "see" what the design of your existing system actually looks like.

The object model repository created by the Javelin modeler is 100% compatible with the Javelin Modeler+Coder so at any time you can upgrade to the modeler+coder and generate and manage source code based on your design.

The Javelin modeler+coder is a complete, lightweight, full lifecycle, object modeling and code generation and management solution to be used with any Java IDE (eg., Eclipse, Netbeans etc.,). It is perfect for developers who want the productivity boost that zero time code generation and management can give while still maintaining control over their code.

Developers can upgrade from the freeware Javelin Modeler at any time and generate and manage the code for object models produced in the freeware modeler.

Want the ability to transfer designs between C++ and Java?
Your Javelin license key also works with Visual Classworks, the C++ sister product of Javelin. Designs created in Javelin can be copied and then opened in Visual Classworks and visa versa.

Tutorial: We walk you through the steps required to create and manage your first Javelin project and use Hibernate* to persist your objects

Learn how to create a simple Java pet shop project from scratch and persist it using Hibernate*. We recommend that you first view some of the animated demonstrations above to get a feel for how to "drive" around in Javelin.

Javelin/Hibernate tutorial.

*This tutorial uses Hibernate for the example but the steps are essentially the same for any JDO implementation (eg., JPOX/Kodo/VOA): simply select the appropriate JDO implementation instead of Hibernate in the persistence options of your project.
