Constructor Details

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.
