Oracle Fusion Middleware Java API Reference for Identity Connector Framework
11g Release 2 (11.1.2)

The Connector framework provides a consistent, generic layer between calling applications and the Connector bundles that access target resources.


org.identityconnectors.common Common utilities for all Connectors.
org.identityconnectors.common.logging This package is responsible for providing logging to the Framework and the Connectors.
org.identityconnectors.common.pooling Contains pooling configuration class only.
org.identityconnectors.common.script Scripting support in ICF. Provides facility to secure String and ByteArray, so it is securely stored in a memory (or transported to Connector Server).
org.identityconnectors.framework.api The Connector API presents a consistent view of any Connector, regardless of which operations the connector actually implements.
org.identityconnectors.framework.spi 'Service Provider Interface' package - the developer of a connector-bundle implements the SPI.
org.identityconnectors.test.common The org.identityconnectors.test.common package offers a set of utility classes and methods useful to connector tests.


The Connector framework provides a consistent, generic layer between calling applications and the Connector bundles that access target resources. Each target resource may be a system or application in its own right, but a Connector bundle enables any calling application to manage objects that exist on the target resource.

Calling applications use the Connector API; Connector bundles implement the Connector SPI. The Connector API (org.identityconnectors.framework.api) is generic (in that it can be used to manipulate any type of object, not merely accounts), but the Connector API is optimized to support provisioning operations and password management. Every supported operation is synchronous to the caller.

This Toolkit is designed to support development with minimal dependencies of Connector bundles that implement the SPI. The Toolkit allows a developer to implement a Connector bundle and to test the bundle within the Connector framework so there is no need to implement it or test it within the context of each calling application.

The developer of a Connector bundle is expected to implement the operations (Java interfaces within the org.identityconnectors.framework.spi.operations package) that make the most sense for the target resource the developer intends to support. The developer is expected to be appropriately flexible in tolerating inputs, to be as reasonably robust in handling errors, and to throw errors whenever it is prudent to do so. Applications that use Connectors should expect java.lang.IllegalArgumentException, java.lang.UnsupportedOperationException, java.lang.IllegalStateException and other subclasses of java.lang.RuntimeException.

NOTE: The developers of this framework made a conscious decision to throw RuntimeException (and subclasses of RuntimeException) rather than using declared exceptions. The reasoning, briefly, is as follows:

  1. Declared exceptions tend to bloat code (and changes in declared exceptions tend to ripple).
  2. RuntimeException is ubiquitous; any piece of code can throw them (even without intending to do so).
  3. Java defines subclasses of RuntimeException that cover most common situations.

One of the main functions of this framework is to prevent coupling between a Connector and any application that uses it. A calling application will be coupled only to this framework and not to any specific Connector.

The design for Connectors derives from requirements of the Sun Identity Manager product. Sun Identity Manager currently supports remote management of target resources through its Resource Adapter technology. Sun Identity Manager and its deployers have developed more than seventy Resource Adapters for enterprise customers who needed provisioning solutions for their heterogeneous environments. Connectors represent the next generation of this technology. Connectors are designed to minimize coupling, to maximize re-use, and to harness the power of open-source development to achieve best-of-breed solutions.
