You can create an application client that runs in the Apache Geronimo application client container rather than running in your local Java environment. The main purpose of the Geronimo client application container is to provide a standard set of services to a client program without forcing the client application to specify a list of dependencies - in other words ease-of-development. The client code can lookup Geronimono Geronimo components such as resources, EJBs, and connectors via standard JNDI lookup. This example creates the simplest application client that can talk to a Geronimo server and place a message in the Geronimo console.

Create a client jar file for a simple example with these files. The client will write a message "CLIENT RUNNING..." on the Geronimo console:

You can run the Application Client with this command:

java -jar %GERONIMO_HOME%/bin/client .jar JEE5JavaEE5/EXAMPLEClient/2.1/car

You should notice the application client message in the Geronimo console.
