JPA Diagram Editor Project


The JPA Diagram Editor enables the JPA developers to create, view, and edit their business data model as graphical diagram. For detailed information, see the project proposal.

The JPA Diagram Editor recently passed successfully a Move Review. We are now in transitional state of moving the code and the infrastructure from the WTP Incubator to the WTP Dali project.
