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 objectRegistry
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 objectRegistry
for the local host on the specifiedport
.- 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 objectRegistry
on the specifiedhost
on the default registry port of 1099. Ifhost
isnull
, 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 objectRegistry
on the specifiedhost
andport
. Ifhost
isnull
, 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 objectRegistry
on the specifiedhost
andport
. Communication with this remote registry will use the suppliedRMIClientSocketFactory
csf
to createSocket
connections to the registry on the remotehost
andport
.- Parameters:
-
host
- host for the remote registry -
port
- port on which the registry accepts requests -
csf
- client-sideSocket
factory used to make connections to the registry. Ifcsf
is null, then the default client-sideSocket
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:
- 1.2
createRegistry
public static Registry createRegistry(int port) throws RemoteException
Creates and exports aRegistry
instance on the local host that accepts requests on the specifiedport
.The
Registry
instance is exported as if the staticUnicastRemoteObject.exportObject
method is invoked, passing theRegistry
instance and the specifiedport
as arguments, except that theRegistry
instance is exported with a well-known object identifier, anObjID
instance constructed with the valueObjID.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 aRegistry
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 givenport
using aServerSocket
created from the suppliedRMIServerSocketFactory
.The
Registry
instance is exported as if the staticUnicastRemoteObject.exportObject
method is invoked, passing theRegistry
instance, the specifiedport
, the specifiedRMIClientSocketFactory
, and the specifiedRMIServerSocketFactory
as arguments, except that theRegistry
instance is exported with a well-known object identifier, anObjID
instance constructed with the valueObjID.REGISTRY_ID
.- Parameters:
-
port
- port on which the registry accepts requests -
csf
- client-sideSocket
factory used to make connections to the registry -
ssf
- server-sideServerSocket
factory used to accept connections to the registry - Returns:
- the registry
- Throws:
-
RemoteException
- if the registry could not be exported - Since:
- 1.2
