Running the cart Application Client Using Ant

    When you run the client, the application client container injects any component references declared in the application client class, in this case the reference to the Cart enterprise bean. To run the application client, perform the following steps.

  1. In a terminal window, go to this directory:

  2. Type the following command:

    ant run

    This task will retrieve the application client JAR, cartClient.jar and run the application client. cartClient.jar contains the application client class, the helper class BookException, and the Cart business interface.

    This is the equivalent of running:

    appclient -client cartClient.jar
  3. In the terminal window, the client displays these lines:

    [echo] running application client container.
    [exec] Retrieving book title from cart: Infinite Jest
    [exec] Retrieving book title from cart: Bel Canto
    [exec] Retrieving book title from cart: Kafka on the Shore
    [exec] Removing "Gravity’s Rainbow" from cart.
    [exec] Caught a BookException: "Gravity’s Rainbow" not in cart.
    [exec] Result: 1
