public class CallerPrincipalCallback extends Object implements Callback
Callback for setting the container's caller (or remote user) principal.

This callback is intended to be called by a serverAuthModule during its validateRequest processing.

  • Constructor Details

    • CallerPrincipalCallback

      public CallerPrincipalCallback(Subject subject, Principal principal)
      Create a CallerPrincipalCallback to set the container's representation of the caller principal

      The CallbackHandler must use the argument Principal to establish the caller principal associated with the invocation being processed by the container. When the argument Principal is null, the handler must establish the container's representation of the unauthenticated caller principal.

      The handler may perform principal mapping of non-null argument Principal values, but it must be possible to configure the handler such that it establishes the non-null argument Principal as the caller principal.

      Parameters:
      subject - The Subject in which the container will distinguish the caller identity.
      principal - The Principal that will be distinguished as the caller principal. This value may be null.

    • CallerPrincipalCallback

      public CallerPrincipalCallback(Subject subject, String name)
      Create a CallerPrincipalCallback to set the container's representation of the caller principal.

      The CallbackHandler must use the name argument to establish the caller principal associated with the invocation being processed by the container. When the name argument is null, the handler must establish the container's representation of the unauthenticated caller principal (which may or may not be equal to null, depending on the requirements of the container type).

      The handler may perform principal mapping of non-null values of name, but it must be possible to configure the handler such that it establishes the non-null argument value as the value returned when getName is called on the established principal.

      Parameters:
      subject - The Subject in which the container will distinguish the caller identity.
      name - The String value that will be returned when getName() is called on the principal established as the caller principal or null.
