Dali JPA Tools

JPA 2.0 Support and EclipseLink 2.0 Platform

    A number of new JPA 2.0 concepts have been implemented in this milestone in both the Generic and EclipseLink (2.0) platforms. An EclipseLink 2.0 Platform has been added for more customized EclipseLink support.

JPA 2.0 Cache support

    Shared-Cache-Mode and Cacheable support have been added to the Dali UI, with persistence-unit, platform, and inheritance based defaults.

JPA 2.0 Canonical Metamodel generation

    Dali has added native support for JPA 2.0 canonical metamodel generation. Dali allows you to specify a source folder for the metamodel to be generated. The metamodel is updated automatically when changes are made to entities in the persistence unit. This is offered as an alternative to APT based implementations that may be offered by JPA implementations.

Document version upgrade

    To help with migration from JPA 1.0 to JPA 2.0, Dali offers a menu item on XML artifacts that can be updated to a newer version, which is necessary to get the latest UI for 2.0 features.
