An introduction to Java RMI

Expanded as Remote Method Invocation, Java RMI is all about knowing and understanding stub and skeleton. It is an API which aims at offering a mechanism which is aimed at creating distributed application on the Java Platform. RMI is a high end tool which enables an object to raise methods within its framework so that it can run in another JVM. As explained Java Remote Method Invocation assignment help, RMI also offers the users with the provision to carry out remote communication between applications that employ two objects namely the stub and skeleton.

Students Learn About the Steps to Write RMI Program

RMI (Remote Method Invocation) as explained above is popular as an API which presents the users with mechanism to develop distributed application using Java platform. RMI also makes use of stub and skeleton object to enable easy and free flowing communication with the targeted remote object. By remote object it is indicative of an object that has a method open for invocation from another JVM. Students seeking Java Remote Method Invocation essay assignment help must understand the stub and skeleton objects:

  • Stub – It can be explained as an object which acts as a gateway to be used from client side. It invites and routes all the outgoing requests along with residing at the client side. It endows apt representation for the remote object. As soon as the caller invokes method on the stub object, it enacts on it and start performing the below listed tasks:
    • It establishes a connection with remote Virtual Machine (JVM),
    • It creates, writes and sends (marshals) the parameters on to the remote Virtual Machine (JVM),
    • It stands waiting for the result and reads (unmarshals) so as to return value or exception
    • Ultimately it returns value to the respective caller

Explaining the Architecture of RMI Application

Inside the structure of an RMI application, the creators write two programs namely the server program (that is based on the server) and a client program (which rests at the client’s end). Within the server program, the remote object is developed and referred to an object which is made easily available for the client with the help of registry. It has a client program requests, so that the remote objects can be placed on the server as well as invoke its methods. You can enjoy assignment writing on java with help of us.

Listed below is a diagram that presents the architecture of an RMI application:

  • Transport Layer – It is an important layer that forms a link between the client and respective server. Also, it aims at managing the existing connection along with establishing new connections.
  • Stub – It is defined as a representation (proxy) of the remote objecting resting with the client. It is situated within the client system and acts as a gateway through which the client program can be managed.
  • Skeleton – It is defined as an object which rests on server side. It remains in direct communication between Stub so that requests can be passed onto the remote object.
  • RRL (Remote Reference Layer) – It is explained as a layer which handled the references sent by the client onto the remote object.

Explains in Detail the Working of an RMI Application

Technical courses expect the students to research and learn about the functionality of different APIs. Java Remote Method Invocation case study assignment help explains the below listed points on how RMI application works −

  • The first step indicates the process wherein client makes a call to the remote object. The same is then received by stub and is passed to the RRL.
  • Second step explains the process wherein client-side RRL takes in the request. It is also explained as the method of invoking of the object remoteRef. It then sends the request to the RRL which is present on the side of the server.
  • Third stage indicates the process wherein the RRL on the server side sends the request to the Skeleton (which can be defined as a proxy on the server). It then invokes the required object that is present on the server.
  • Last step is when the result is passed onto the client.
