WCSRealm class
The WCSRealm class extends from the PaymentServletRealm class to allow the WebSphere Commerce Payments servlet to use the administrator information that is already registered in the user tables. This administrator information is used for WebSphere Commerce Payments administrators, so that you do not have to define another set of administrator IDs in order to use the WebSphere Commerce Payments user interface.
The WCSRealm class is called by the servlet whenever an administrator tries to access the servlet, to check that the person is an authenticated user. WebSphere Commerce Payments maintains a User Permissions table to control the access rights assigned to different administrators.
