Class LocateRegistry

Table des matières

  • 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

                            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

                            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:

      • 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:

      • 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

      • 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.
        Returns:
        reference (a stub) to the remote registry
        Throws:
        RemoteException - if the reference could not be created
        Since:

      • createRegistry

        public static Registry createRegistry(int port)
                               throws RemoteException
        Creates and exports a Registry instance on the local host that accepts requests on the specified port.

        The Registry instance is exported as if the static UnicastRemoteObject.exportObject method is invoked, passing the Registry instance and the specified port as arguments, except that the Registry instance is exported with a well-known object identifier, an ObjID instance constructed with the value ObjID.REGISTRY_ID.

        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 instance on the local host that uses custom socket factories for communication with that instance. The registry that is created listens for incoming requests on the given port using a ServerSocket created from the supplied RMIServerSocketFactory.

        The Registry instance is exported as if the static UnicastRemoteObject.exportObject method is invoked, passing the Registry instance, the specified port, the specified RMIClientSocketFactory, and the specified RMIServerSocketFactory as arguments, except that the Registry instance is exported with a well-known object identifier, an ObjID instance constructed with the value ObjID.REGISTRY_ID.

        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:
        RemoteException - if the registry could not be exported
        Since:
