Java RMI and Distributed Object Application

• Ant script for deployment
• Maven for package dependency, build and project management

Building

Build httpd-server

The httpd-server module for the Dynamic code downloading using Java RMI (Using the java.rmi.server.codebase Property). This is optional for production use.

cd httpd-server
mvn clean package

Build oracle-rmi-tute

A complete RMI application using the Maven multi module structure. The application adapts the tutorial from Java RMI Tutorial trail.

cd oracle-rmi-tute
mvn clean package

Deployment and Running

Basically, the RMI deployment steps involve 4 distributed components, each of them can be run in different machines or different processes on a single machine. In this example, the Ant script will create the possible deployment structure and will copy the artifacts in place for running the application.

Deploy

ant clean deploy

Running

Starting each components. Must be in order:

1. Start httpd server (for Remote Interface and parametric objects)
2. Start rmiregistry process
3. Start RMI server
4. Start RMI client

Example: running oracle-rmi-tute

cd deploy/httpd
start.bat  (or start.sh)
cd ../registry
startregistry.bat  (startregistry.sh)
cd ../server
start.bat  (or start.sh)
cd ../client
start.bat  (or start.sh)

Notes

• Note that the httpd-server component is optional. If there is a production web server available (e.g. elsewhere running Apache httpd) then the Remote Interface and parametric artifacts can be better deployed there and recommended for production. But in this case, the httpd-server implementation is back by Jetty for ease of development.
