Building and Running order

This section describes how to build, package, and run order.

Creating the Database Tables

The database tables are automatically created by the create-tables task, which is called before you deploy the application with the ant deploy task. To manually create the tables, do the following:

  1. In a terminal navigate to

    2. <INSTALL>/javaeetutorial5/examples/ejb/order/

  2. Enter the following command:

    3. ant create-tables

Note: The first time the create-tables task is run, you will see error messages when the task attempts to remove tables that don't exist. Ignore these error messages. Subsequent calls to create-tables will run with no errors, and reset the database tables.

Building and Packaging the Application

To build the application components of order, enter the following command: 

ant

This runs the default task, which compiles the source files and packages the application into an EAR file located at <INSTALL>/examples/ejb/order/dist/order.ear.

Deploying the Application

To deploy the EAR, make sure the Application Server is started, then enter the following command: 

ant deploy

After order.ear is deployed, a client JAR, orderClient.jar, is retrieved. This contains the application client.

Running the Application

To run the application client, enter the following command: 

ant run

You will see the following output: 

...
run:
  [echo] Running appclient for Order.

BUILD SUCCESSFUL

Note: Before re-running the application client, you must reset the database by running the create-tables task.

The all Task

As a convenience, the all task will build, package, deploy, and run the application. To do this, enter the following command: 

ant all

Undeploying order

To undeploy order.ear, enter the following command: 

ant undeploy
