What is RMI explain its architecture?

Overview of RMI Architecture. RMI stands for Remote Method Invocation. It is an API provided by java that allows an object residing in one JVM (Java Virtual Machine) to access or invoke an object running on another JVM. The other JVM could be on the same machine or remote machine.

What are the layers of RMI architecture?

The RMI system consists of three layers: the stub/skeleton layer, the remote reference layer, and the transport layer.

Why RMI is used in enterprise application development?

The primary advantages of RMI are: Object Oriented: RMI can pass full objects as arguments and return values, not just predefined data types. This means that you can pass complex types, such as a standard Java hashtable object, as a single argument.

What is the difference between RPC and RMI?

RPC and RMI both are similar but the basic difference between RPC and RMI is that RPC supports procedural programming, on the other hand, RMI supports object-oriented programming. 1. RPC is a library and OS dependent platform. Whereas it is a java platform.

What are the different terms that are used in RMI?

What are the different terms that are used in RMI?

  • Remote object: – It is an object that is provided on another computer to request the object by sending a message to the object to the remote servers.
  • Server object:
  • rmiregistry:
  • Rmic:

What are the different types of classes that are used in RMI?

RMI Interfaces and Classes

  • The Remote Interface. All remote interfaces extend, either directly or indirectly, the interface java.rmi.remote .
  • The RemoteException Class. The java.
  • The RemoteObject Class and its Subclasses.
  • Passing Nonremote Objects.
  • Passing Remote Objects.
  • equals and hashCode.
  • toString.
  • clone.

How does an RMI work?

A typical client program obtains a remote reference to one or more remote objects on a server and then invokes methods on them. RMI provides the mechanism by which the server and the client communicate and pass information back and forth. Such an application is sometimes referred to as a distributed object application.

What is the disadvantage of RMI?

Disadvantages of RMI: – Less efficient than Socket objects. – Assuming the default threading will allow ignoring the coding, being the servers are thread- safe and robust. – Cannot use the code out of the scope of java. – Security issues need to be monitored more closely.

Why is RMI more efficient than RPC?

RMI (Remote Method Invocation) It supports object-oriented programming. It is more efficient in comparison to RPC. It creates less overhead in comparison to RPC. In this, objects are passed as parameters.

Does RMI use TCP?

Actually, it uses UDP, despite the docs claiming it’s TCP.

How do I use RMI?

The is given the 6 steps to write the RMI program.

  1. Create the remote interface.
  2. Provide the implementation of the remote interface.
  3. Compile the implementation class and create the stub and skeleton objects using the rmic tool.
  4. Start the registry service by rmiregistry tool.
  5. Create and start the remote application.

Which of the following is true about RMI?

Explanation: Remote method invocation RMI allows us to invoke a method of java object that executes on another machine. Explanation: Remote class does not define any methods, its purpose is simply to indicate that an interface uses remote methods.
