The Java RFC Class Library offers classes and objects that allow you to write client application programs that send RFC requests to R/3.

The exposed Java RFC client Interfaces are defined in the com.sap.rfc package.

Exceptions are defined in the com.sap.rfc.exception package

The following features apply to virtually all Java RFC classes:

• Can be cloned by calling the clone() method
• Can be converted to a string representation by calling the toString() method

The next topics discuss the various interfaces and classes and how to use them.
