Remote Method Invocation (RMI) Code Samples

Print-friendly Version

The Remote Method Invocation (RMI) API allows remote communication between programs written in the Java programming language. It enables an object running in one Java virtual machine (JVM¹) to invoke methods on an object running in another Java virtual machine.

• Compute Pi Example
• File Transfer Example
• Servlets and Serialization Example

• Compute.java defines the remotely accessible part of a compute engine. For supporting information see The Java Tutorial: Remote Method Invocation.
  
  
• ComputeEngine.java implements the Compute.java methods and provides the main method for the application. For supporting information see The Java Tutorial: Remote Method Invocation.
  
  
• ComputePi.java is the client class for the ComputeEngine.java program. For supporting information see The Java Tutorial: Remote Method Invocation.
  
  
• Pi.java is another client class for the ComputeEngine.java program. For supporting information see The Java Tutorial: Remote Method Invocation.
  
  
• Task.java defines the interface between Compute.java and the work it needs to do. For supporting information see The Java Tutorial: Remote Method Invocation.
  
  

• FileClient.java remotely invokes any methods specified in the FileInterface remote interface. For supporting information see Distributed Java Programming with RMI and CORBA.
  
  
• FileImpl.java provides the implementation for FileInterface. For supporting information see Distributed Java Programming with RMI and CORBA.
  
  
• FileInterface.java is the remote interface for a file download application. For supporting information see Distributed Java Programming with RMI and CORBA.
  
  
• FileServer.java implements a server that creates and installs an instance of the RMISecurityManager, creates an instance of the remote object (FileImpl), and registers the object with the RMI registry. For supporting information see Distributed Java Programming with RMI and CORBA.
  
  

• Servlets and Serialization Source downlaod shows how to incorporate RMI technology into servlets. For supporting information see Java Servlets and Serialization with RMI.
