public static ServerSocketFactory getDefault()
Returns the default instance of this class.- Returns:
- ServerSocketFactory instance of this class.

createServerSocket
public ServerSocket createServerSocket(int port) throws IOException
Creates a server socket on a specified port. A port of0
creates a socket on any free port or if the tcp.port.range system property is set it creates a socket within the specified port range.The maximum queue length for incoming connection indications (a request to connect) is set to
50
. If a connection indication arrives when the queue is full, the connection is refused.- Parameters:
port
- the port number, or0
to use any free port or if the tcp.port.range property set to use any available port within the specified port range.- Throws:
IOException
- if an I/O error occurs when opening the socket.
-
createServerSocket
public ServerSocket createServerSocket(int port, int backlog) throws IOException
Creates a server socket on a specified port. A port of0
creates a socket on any free port or if the tcp.port.range system property is set it creates a socket within the specified port range.The maximum queue length for incoming connection indications (a request to connect) is set to the
backlog
parameter. If a connection indication arrives when the queue is full, the connection is refused.- Parameters:
port
- the port number, or0
to use any free port or if the tcp.port.range property set to use any available port within the specified port range.backlog
- the maximum length of the queue.- Throws:
IOException
- if an I/O error occurs when opening the socket.

createServerSocket
public ServerSocket createServerSocket(int port, int backlog, InetAddress bindAddr) throws IOException
Create a server with the specified port, listen backlog, and local IP address to bind to. The bindAddr argument can be used on a multi-homed host for a ServerSocket that will only accept connect requests to one of its addresses. If bindAddr is null, it will default accepting connections on any/all local addresses. The port must be between 0 and 65535, inclusive.- Parameters:
port
- the local TCP portbacklog
- the listen backlogbindAddr
- the local InetAddress the server will bind to- Throws:
IOException
- if an I/O error occurs when opening the socket.
