In Java Remote Method Invocation (RMI), the stub plays a crucial role as the client-side representation of the remote object. The primary function of the stub is to act as a proxy or gateway for the client, handling all outgoing requests to the server where the actual remote object resides[1][2][3][4][5][6][8].
Key Functions of the Stub in RMI
Communication Interface: The stub serves as the intermediary between the client application and the remote object on the server. It provides the client with a local representation of the remote object, allowing the client to invoke methods on the server-side object as if it were local[1][2][3][4][5][6][8].
Marshalling of Requests: The stub is responsible for marshalling, which involves packaging the method calls along with their associated parameters into a form suitable for network transmission. This process includes serializing the parameters into a byte stream[2][3][6].
Network Transmission: After marshalling the data, the stub sends the method invocation request across the network to the server-side skeleton[2][3][4][5][6].
Receiving and Unmarshalling Responses: Once the server processes the request and returns the result, the stub receives the response. It then unmarshals the response, which involves converting the received byte stream back into a suitable format or objects that the client application can use[2][3][6].
Error Handling: The stub also plays a role in error handling by catching exceptions that may occur during the remote method invocation process. If an exception occurs on the server side during t...
