Class LocateRegistry

java.lang.Object
  |
  +--java.rmi.registry.LocateRegistry
public final class LocateRegistry
extends Object

LocateRegistry is used to obtain a reference to a bootstrap remote object registry on a particular host (including the local host), or to create a remote object registry that accepts calls on a specific port.

Note that a getRegistry call does not actually make a connection to the remote host. It simply creates a local reference to the remote registry and will succeed even if no registry is running on the remote host. Therefore, a subsequent method invocation to a remote registry returned as a result of this method may fail.

Since:
JDK1.1

Method Detail

getRegistry

public static Registry getRegistry()
                            throws RemoteException
Returns a reference to the the remote object Registry for the local host on the default registry port of 1099.
Returns:
reference (a stub) to the remote object registry
Throws:
RemoteException - if the reference could not be created
Since:
JDK1.1

getRegistry

public static Registry getRegistry(int port)
                            throws RemoteException
Returns a reference to the the remote object Registry for the local host on the specified port.
Parameters:
port - port on which the registry accepts requests
Returns:
reference (a stub) to the remote object registry
Throws:
RemoteException - if the reference could not be created
Since:
JDK1.1

getRegistry

public static Registry getRegistry(String host)
                            throws RemoteException
Returns a reference to the remote object Registry on the specified host on the default registry port of 1099. If host is null, the local host is used.
Parameters:
host - host for the remote registry
Returns:
reference (a stub) to the remote object registry
Throws:
RemoteException - if the reference could not be created
Since:
JDK1.1

getRegistry

public static Registry getRegistry(String host,
                                   int port)
                            throws RemoteException
Returns a reference to the remote object Registry on the specified host and port. If host is null, the local host is used.
Parameters:
host - host for the remote registry
port - port on which the registry accepts requests
Returns:
reference (a stub) to the remote object registry
Throws:
RemoteException - if the reference could not be created
Since:
JDK1.1

getRegistry

public static Registry getRegistry(String host,
                                   int port,
                                   RMIClientSocketFactory csf)
                            throws RemoteException
Returns a locally created remote reference to the remote object Registry on the specified host and port. Communication with this remote registry will use the supplied RMIClientSocketFactory csf to create Socket connections to the registry on the remote host and port.
Parameters:
host - host for the remote registry
port - port on which the registry accepts requests
csf - client-side Socket factory used to make connections to the registry. If csf is null, then the default client-side Socket factory will be used in the registry stub.
Throws:
RemoteException - if the reference could not be created
Since:
JDK1.2

createRegistry

public static Registry createRegistry(int port)
                               throws RemoteException
Creates and exports a Registry on the local host that accepts requests on the specified port.
Parameters:
port - the port on which the registry accepts requests
Returns:
the registry
Throws:
RemoteException - if the registry could not be exported
Since:
JDK1.1

createRegistry

public static Registry createRegistry(int port,
                                      RMIClientSocketFactory csf,
                                      RMIServerSocketFactory ssf)
                               throws RemoteException
Creates and exports a Registry on the local host that uses custom socket factories for communication with that registry. The registry that is created listens for incoming requests on the given port using a ServerSocket created from the supplied RMIServerSocketFactory. A client that receives a reference to this registry will use a Socket created from the supplied RMIClientSocketFactory.
Parameters:
port - port on which the registry accepts requests
csf - client-side Socket factory used to make connections to the registry
ssf - server-side ServerSocket factory used to accept connections to the registry
Returns:
the registry
Throws:
