Its aim is not to be exhaustive but rather to be customized and enriched according to your needs.

How does it work ?

The "EJB 2 to EJB 3" booster is supplied with Mia-Modernization. Installing Mia-Modernization will install this booster and the needed Eclipse plugin to use it.

Indicate where the refactoring result should be saved, by default the original application is overwritten :



Click on the "Transform" button and visualize the result in Eclipse : your application has been transformed.

For more details, please read the supplied documentation.

What are the top features ?

  1. Using composite metamodel

    2. In order to facilitate the customization of the retro-modelization, your application will be loaded as 3 models conformed the following metamodels :

    • the JavaApplication composite metamodel, including the J2SE5 metamodel and the Disk metamodel,
    • the EjbJar2_0 metamodel, reflection of ejb configuration files (ejb-jar.xml)

    The models of the application are linked together to facilitate writing the transformation rules.

  1. Saving the refactored application

    2. Visualize in Eclipse the result of your refactoring thanks to a writer dedicated to the J2SE5 metamodel allowing re-writing your transformed application at the right place. By default, the original application is overriden.

    2. Thanks to the transformation engine of Mia-Modernization based on inference rules, you can easily customize your retro-modelization. The rules are specified and written with Mia-Modernization Architect (based on Mia-Transformation). In evaluation model, this booster can be modified up to 15 rules and 5 services.
