Package examples.rmi.multihello Description

This package takes the simple "HelloWorld" RMI example and extends it to bind multiple unique names in the registry and then display multiple invocations of each to the simple client.

In this package is the Remote interface "Hello," which is implemented by the "HelloImpl" class. The "sayHello" class invokes the Remote class from the command line.

Also included in this directory are build scripts for NT, and UNIX. The script compiles the files in this directory and runs the WebLogic RMI compiler on the implementation class.

There are detailed instructions on converting Sun RMI classes to use WebLogic RMI in the Developers Guide. The instructions here are brief and assume that you have or will look at the Developers Guide.

The following section describes how to build and run the examples:

1. Build the example
2. Configure the server
3. Run the example

Build the example

1. Set up your development shell as described in Setting up your environment.

   The build script is build.xml.

   Run the build script using the following Java ant command:
   prompt> ant

   The script will build the example and place the files in the correct locations in your WebLogic Server distribution:

   • Client files: in SAMPLES_HOME\server\stage\examples\clientclasses\
   • EJBean: in SAMPLES_HOME\server\config\examples\applications\rmi_multihello.jar

Configure the server

To Register HelloImpl as a startup class:

1. Start the server with the examples configuration in a new command shell.
2. Bring up the Administration Console in your browser.
3. Click to expand the Deployments node in the left pane.
4. Click to expand the Startup & Shutdown node in the left pane.
5. Select the multihello server.
6. Select the Targets tab in the right pane to display the Available and Chosen targets.
7. Deploy the multihello startup class on the examplesServer.

Run the example

1. Since startup classes are only activated when the server boots, you will need to re-start the server with the examples configuration.

2. In your development shell, run the client with the following command:

     prompt> ant run
