Azzyzt JEE Tools is a set of Eclipse plugins for creating a so-called "azzyzted" project, and for creating code from a model. Azzyzt uses Java JPA entities as a model, and from that model it creates an enterprise application, ready to be deployed in a Java EE 6 application server like GlassFish 3.1, ready to be accessed via CORBA, SOAP, and REST. Thus the generated application is a set of Web services, providing all that you need in a typical CRUD application. Generated enterprise applications have separate source folders for generated and developer-supplied content. You can add your own functionality to a well-engineered base project. Azzyzt JEE Tools is not about user interfaces. It is expected that the generated application is accessed by a RIA frontend or by a fat client.
