Each question has hints that you may use when you are stuck on a problem. Only a fully submitted solution will be considered for a Geek Bit. Each submission will be tested on our critical test data. Stub communicates with this skeleton to pass request to the remote object.RRL(Remote Reference Layer) − It is the layer which manages the references made by the client to the remote object.Working of an RMI ApplicationThe following points summarize how an RMI application works −.When the client makes a call to the remote object, it is received by the stub which eventually passes this request to the RRL.When the client-side RRL receives the request, it invokes a method called invoke of the object remoteRef. You can solve the questions in C++, Java, Python. It is mainly used for the creation of distributed systems.

It resides in the client system it acts as a gateway for the client program.Skeleton − This is the object which resides on the server side. RMI (Remote Method Invocation) is an API used to access objects running on another JVM(Server-side).

These threads use shared memory but they act independently hence if there is an exception in threads that do not affect the working of other threads despite them sharing the same memory. It manages the existing connection and also sets up new connections.Stub − A stub is a representation (proxy) of the remote object at client. Typically, we can define threads as a subprocess with lightweight with the smallest unit of processes and also has separate paths of execution. Architecture of an RMI ApplicationIn an RMI application, we write two programs, a server program (resides on the server) and a client program (resides on the client).Inside the server program, a remote object is created and reference of that object is made available for the client (using the registry).The client program requests the remote objects on the server and tries to invoke its methods.The following diagram shows the architecture of an RMI application.Let us now discuss the components of this architecture.Transport Layer − This layer connects the client and the server.
