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. While retaining the benefits of JCo and JCA like transactions, security, connection pooling, etc., developers can focus on writing business logic because the need for boilerplate code is largely reduced.
