Exadel Flamingo provides a set of commands that help a developer to generate initial code. To bootstrap a project, a developer answers a few questions in a wizard. Based on these questions, a standard project is generated. Flamingo is based on Maven, therefore the new application is generated according to Maven conventions, making it easy for people familiar with Maven to navigate through the project.
The generated code provides all the necessary plumbing and connectivity from Flex or JavaFX to Seam or Spring. A developer only needs to focus on business functionality; Flamingo takes care of the rest. All communications between the user interface and Seam or Spring components are taken care of by Exadel Flamingo.
Exadel Flamingo also provides a set of Flex components that make it extremely convenient to support specific features of Seam on the client side.
The Envers project aims to enable easy versioning of persistent JPA classes. All that you have to do is annotate your persistent class or some of its properties, that you want to version, with @Versioned. For each versioned entity, a table will be created, which will hold the history of changes made to the entity. You can then retrieve and query historical data without much effort.
Similarly to Subversion, the library has a concept of revisions. Basically, one transaction commit is one revision (unless the transaction didn't modify any versioned entities). As the revisions are global, having a revision number, you can query for various entities at that revision, retrieving a (partial) view of the database at that revision.
