SAP JCo is based on the JNI (Java Native Interface) which facilitates access to the CPIC library.

It supports SAP (R/3) systems from Release 3.1H upwards, and other mySAP components that have BAPIs or RFMs (Remote Function Modules).

With SAP JCo, you can use synchronous, transactional, queued, and background RFC.

SAP JCo can be used on different platforms
