  - ### RMIJRMPServerImpl

    public RMIJRMPServerImpl(int port, RMIClientSocketFactory csf, RMIServerSocketFactory ssf, Map<String,?> env) throws IOException

    Creates a new `RMIServer` object that will be exported on the given port using the given socket factories.

    Parameters:
      `port` - the port on which this object and the `RMIConnectionImpl` objects it creates will be exported. Can be zero, to indicate any available port.
      `csf` - the client socket factory for the created RMI objects. Can be null.
      `ssf` - the server socket factory for the created RMI objects. Can be null.
      `env` - the environment map. Can be null.
    Throws:
      `IOException` - if the `RMIServer` object cannot be created.
      `IllegalArgumentException` - if `port` is negative.

- ## Method Details

  - ### export

    protected void export() throws IOException
    Description copied from class: `RMIServerImpl`

    Exports this RMI object.

    Specified by:
      `export` in class `RMIServerImpl`
    Throws:
      `IOException` - if this RMI object cannot be exported.

  - ### getProtocol

    protected String getProtocol()
    Description copied from class: `RMIServerImpl`

    Returns the protocol string for this object. The string is `rmi` for RMI/JRMP.

    Specified by:
      `getProtocol` in class `RMIServerImpl`
    Returns:
      the protocol string for this object.

  - ### toStub

    public Remote toStub() throws IOException

    Returns a serializable stub for this `RMIServer` object.

    Specified by:
      `toStub` in class `RMIServerImpl`
    Returns:
      a serializable stub.
    Throws:
      `IOException` - if the stub cannot be obtained - e.g the RMIJRMPServerImpl has not been exported yet.

  - ### makeClient

    protected RMIConnection makeClient(String connectionId, Subject subject) throws IOException

    Creates a new client connection as an RMI object exported through JRMP. The port and socket factories for the new `RMIConnection` object are the ones supplied to the `RMIJRMPServerImpl` constructor.

    Specified by:
      `makeClient` in class `RMIServerImpl`
    Parameters:
      `connectionId` - the ID of the new connection. Every connection opened by this connector server will have a different id. The behavior is unspecified if this parameter is null.
      `subject` - the authenticated subject. Can be null.
    Returns:
      the newly-created `RMIConnection`.
    Throws:
      `IOException` - if the new `RMIConnection` object cannot be created or exported.

  - ### closeClient

    protected void closeClient(RMIConnection client) throws IOException
    Description copied from class: `RMIServerImpl`

    Closes a client connection made by `makeClient`.

    Specified by:
      `closeClient` in class `RMIServerImpl`
    Parameters:
      `client` - a connection previously returned by `makeClient` on which the `closeClient` method has not previously been called. The behavior is unspecified if these conditions are violated, including the case where `client` is null.
    Throws:
      `IOException` - if the client connection cannot be closed.

  - ### closeServer

    protected void closeServer() throws IOException

    Called by `RMIServerImpl.close()` to close the connector server by unexporting this object. After returning from this method, the connector server must not accept any new connections.

    Specified by:
      `closeServer` in class `RMIServerImpl`
    Throws:
      `IOException` - if the attempt to close the connector server failed.
