What do you mean by Java RMI?

Java Remote Method Invocation
In computing, the Java Remote Method Invocation (Java RMI) is a Java API that performs remote method invocation, the object-oriented equivalent of remote procedure calls (RPC), with support for direct transfer of serialized Java classes and distributed garbage-collection.

What is Java RMI used for?

RMI stands for Remote Method Invocation. It is a mechanism that allows an object residing in one system (JVM) to access/invoke an object running on another JVM. RMI is used to build distributed applications; it provides remote communication between Java programs. It is provided in the package java.

Is Java RMI still relevant?

Conclusion. RMI and CORBA(Common Object Request Broker Architecture) attempt to solve a problem that people thought was important in the early 1990s. However, today we can’t consider RMI as modern technology and nowadays we have REST, SOAP as the de-facto standards for communicating with remote services.

Is RMI a RPC in Java?

Remote method invocation (RMI) is an API, which implements RPC in java with support of object oriented paradigms. You can think of invoking RPC is like calling a C procedure. RPC supports primitive data types where as RMI support method parameters/return types as java objects. RMI is easy to program unlike RPC.

What port is used by Java RMI connection?

The following ports are used for making Java™™ Management Extensions (JMX) connections with the server: The remote method invocation (RMI), also known as the ORB bootstrap, port is designed to improve performance and communication with the server. The RMI connection is JSR 160 RMI compliant. The default setting of the RMI port is 2809

What is the difference between RMI and CORBA?

CORBA interfaces are defined in IDL and RMI interfaces are defined in Java.

  • while RMI does not since local objects are passed by copy and remote objects are passed by reference.
  • CORBA was designed with language independence in mind.
  • CORBA objects are not garbage collected.

    • How to implement WebLogic RMI?

    Procedures for Implementing WebLogic RMI . The following sections describe how to implement WebLogic Server RMI: Creating Classes That Can Be Invoked Remotely Step 1. Write a Remote Interface. Step 2. Implement the Remote Interface. Step 3. Compile the Java Class. Step 4. Compile the Implementation Class with RMI Compiler

    What are the difference and similarities between RMI and RPC?

    thus inheriting its paradigm; it is an OS-dependent platform.

  • RMI supports object-oriented programming paradigms and is java based.
  • people get a procedure call that looks pretty much like a local call.
