Thus, a UML?model for a component can be used in a black?box test for the component. Further we introduce different design patterns for EJBs, which are motivated by different levels of abstraction, and show that these patterns work smoothly together with our OCL constraint checking. A prototypic implementation of the code generator, supporting our patterns with OCL support, has been integrated into a commercial software development tool.
