In Java Remote Method Invocation (RMI), "binding" refers to the process of associating or registering a remote object with a name in the RMI registry. This process allows client applications to look up remote objects by name to establish a connection and invoke methods on these objects remotely.
When a remote object is created in an RMI application, it must be made accessible to potential clients. Binding the object to a name in the RMI registry is a critical step in this process. The registry acts as a simple naming service where remote objects can be registered with unique names. Once registered, these objects can be accessed by clients from different JVMs, possibly on different hosts.
The binding process typically involves several steps:
Creating a Remote Object: The server program creates an instance of the remote object that needs to be accessible remotely.
Exporting the Remote Object: The remote object is exported to make it available to receive incoming calls from clients. This is often done using UnicastRemoteObject.exportObject.
Registering the Object in the RMI Registry: The remote object is then registered in the RMI registry under a specific name using the bind or rebind methods of the Registry class. The bind method is used if you are registering the object for the first time, while rebind is used to replace an existing binding.
For example, if you have a remote object of a class that implements a Search interface, you might bind it to the registry with a name like "SearchService". Clients can then look up this name in the registry to obtain a stub (a local proxy) for the ...
