The Java Remote Method Invocation (RMI) system allows an object running in one Java Virtual Machine (VM) to invoke methods on an object running in another Java VM. RMI provides for remote communication between programs written in the Java programming language.
This chapter has not yet been updated to reflect features and conventions of the latest release, JDK 6.0.
This trail provides a brief overview of the RMI system and then walks through a complete client/server example that uses RMI's unique capabilities to load and to execute user-defined tasks at runtime. The server in the example implements a generic compute engine, which the client uses to compute the value of
Note: If you are connecting to an existing IDL program, you should use Java IDL rather than RMI.
.
An Overview of RMI Applications
describes the RMI system and lists its advantages. Additionally, this
lesson provides a description of a typical RMI application, composed of
a server and a client, and introduces important terms.
Writing an RMI Server
walks through the code for the compute engine server. This example will
teach you how to design and to implement an RMI server.
Creating A Client Program
takes a look at one possible compute engine client and uses it to
illustrate the important features of an RMI client.
Compiling and Running the Example
shows you how to compile and to run both the compute engine server and
its client.
