The functionality of the REST driver can be extended by using Java. You use an API defined by Java interfaces to create your own custom Java classes that have access to the data passing through the Subscriber and Publisher channels. These classes read and interpret the data, and, optionally, modify the data.
You can also configure Java extensions in the Java class that is available in the driver shim (com.novell.nds.dirxml.driver.rest.RESTDriverShim). The Java class consists of four empty functions. You need to enter the functions to perform operations as required. For more information, see Driver Development Kit in the Identity Manager Developer Documentation page.
