Client library authentication mechanisms

Binding configuration

For service binding using the WebSphere Commerce JCA Messaging subsystem, you can provide the authentication credentials as part of the parameters. See Configuration of transport services used for a message for more information.

Callback handler

The javax.security.auth.callback.CallbackHandler interface is part of the Java library and is used to specify a callback handler that will react to a particular set of callback objects. These callback objects represent authentication objects. The authentication objects are either empty objects that expect the callback handler to populate them, or populated objects that the callback handler can store information about. For information about this interface can be found by reading the API documentation of this interface.

This interface is part of the client library constructor. It is used by the presentation layer to interact with the transport layer to specify authentication information in the transport protocol. By using this interface a client can control the WebSphere Commerce identity token used in the SOAP requests to the remote component. The abstract client library will pass this information to the service binding so the transport can flow the authentication information with the remote request.

WebSphere Commerce component facades using the client library to communicate with another WebSphere Commerce component facade do not need to use this interface. The passing of the authentication information will be managed by the WebSphere Application Server.
