public final class LocateRegistry extends Object
LocateRegistryis 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
getRegistrycall 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:
- 1.1

getRegistry
public static Registry getRegistry() throws RemoteException
Returns a reference to the remote objectRegistryfor 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:
- 1.1
-
getRegistry
public static Registry getRegistry(int port) throws RemoteException
Returns a reference to the remote objectRegistryfor 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:
- 1.1
-
getRegistry
public static Registry getRegistry(String host) throws RemoteException
Returns a reference to the remote objectRegistryon the specifiedhoston the default registry port of 1099. Ifhostisnull, 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:
- 1.1
-
getRegistry
public static Registry getRegistry(String host, int port) throws RemoteException
Returns a reference to the remote objectRegistryon the specifiedhostandport. Ifhostisnull, the local host is used.- Parameters:
host- host for the remote registryport- 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:
- 1.1
-
getRegistry
public static Registry getRegistry(String host, int port, RMIClientSocketFactory csf) throws RemoteException
Returns a locally created remote reference to the remote objectRegistryon the specifiedhostandport. Communication with this remote registry will use the suppliedRMIClientSocketFactorycsfto createSocketconnections to the registry on the remotehostandport.- Parameters:
host- host for the remote registryport- port on which the registry accepts requestscsf- client-sideSocketfactory used to make connections to the registry. Ifcsfis null, then the default client-sideSocketfactory 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 aRegistryinstance on the local host that accepts requests on the specifiedport.The
Registryinstance is exported as if the staticUnicastRemoteObject.exportObjectmethod is invoked, passing theRegistryinstance and the specifiedportas arguments, except that theRegistryinstance is exported with a well-known object identifier, anObjIDinstance 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:
- 1.1
-
createRegistry
public static Registry createRegistry(int port, RMIClientSocketFactory csf, RMIServerSocketFactory ssf) throws RemoteException
Creates and exports aRegistryinstance 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 givenportusing aServerSocketcreated from the suppliedRMIServerSocketFactory.The
Registryinstance is exported as if the staticUnicastRemoteObject.exportObjectmethod is invoked, passing theRegistryinstance, the specifiedport, the specifiedRMIClientSocketFactory, and the specifiedRMIServerSocketFactoryas arguments, except that theRegistryinstance is exported with a well-known object identifier, anObjIDinstance constructed with the valueObjID.REGISTRY_ID.- Parameters:
port- port on which the registry accepts requestscsf- client-sideSocketfactory used to make connections to the registryssf- server-sideServerSocketfactory used to accept connections to the registry- Returns:
- the registry
- Throws:
RemoteException- if the registry could not be exported- Since:
- 1.2
