Hibersap helps developers of Java applications to call business logic in SAP backends. It defines a set of Java annotations to map SAP function modules to Java classes as well as a small, clean API to execute these function modules and handle transaction and security aspects.
Hibersap's programming model is quite similar to those of modern O/R mappers, significantly speeding up the development of SAP interfaces and making it much more fun to write the integration code.
Under the hood, Hibersap either uses the SAP Java Connector (JCo) or a JCA compatible resource adapter to communicate with the SAP backend. ...
Needle is a lightweight framework for testing Java EE components outside of the container in isolation. It reduces the test setup code by analysing dependencies and automatic injection of mock objects. It will thus maximize the speed of development as well as the execution of unit tests.

To implement the State Machine model of behavior with chain of command design pattern. Commands and created out of Actions of a State Model {ENTRY, INPUT, TRANSACTION, EXIT} and can be exectued independently or bundled together to form a chain.
...Similar to the Java reflection API, but generic so it can be used with different implementations, and then be used by various Services like Editors, Constraint-Checkers, Bindings, Persistence, and Transaction.
