getEndpoint

protected Endpoint getEndpoint(SocketFactory factory,

Description copied from class: EndpointBasedClient

Returns an endpoint which uses the given socket factory, if non-null, and may incorporate information (such as the expected server principal) from the given set of constraints, if non-null. Other parameters of the endpoint, such as the target host and port, are irrelevant from the standpoint of this class and can be chosen arbitrarily. Throws an UnsupportedConstraintException if the given constraints lack information needed to construct the endpoint.

Specified by:

getEndpoint in class EndpointBasedClient

Throws:

UnsupportedConstraintException

getKerberosPrincipal

private static KerberosPrincipal getKerberosPrincipal(InvocationConstraints constraints)
                                               throws UnsupportedConstraintException

Returns the kerberos principal specified in the ServerMinPrincipal requirements or preferences of the given constraints. Throws UnsupportedConstraintException if no kerberos principal is specified, a non-kerberos server principal is required, or multiple server principals are required.

Throws:

UnsupportedConstraintException
