Constructor Detail

CallerPrincipalCallback

public CallerPrincipalCallback(Subject s,
                       Principal p)

Create a CallerPrincipalCallback to set the container's representation of the caller principal

Parameters:

s - The Subject in which the container will distinguish the caller identity.

p - The Principal that will be distinguished as the caller principal. This value may be null.

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

CallerPrincipalCallback

public CallerPrincipalCallback(Subject s,
                       String n)

Create a CallerPrincipalCallback to set the container's representation of the caller principal.

Parameters:

s - The Subject in which the container will distinguish the caller identity.

n - The String value that will be returned when getName() is called on the principal established as the caller principal or null.

When the n argument is null, the handler will 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). When the container type requires that a non-null principal be established as the caller principal, the value obatined by calling getName on the principal may not match the argument value.
