This exercise is entirely based on the beans implemented in Exercise 11.2. You’ll modify the TravelAgent EJB so it publishes a text message to a JMS topic when it completes a reservation.
You’ll learn how to create a new JMS topic in JBoss, and configure your bean to use JMS as a resource. You’ll also build a client application that will subscribe to this topic and display any published message. To complete new reservations, you’ll use one of the client applications created for the preceding example.
If JBoss is already running there is no reason to restart it.
Because the exercise uses the ProcessPayment EJB used in recent
exercises, the database must contain the
Ant targets, Java code, and clients here have been borrowed from
If you haven’t already dropped the
PAYMENT table after running the examples in
Exercise 11.2, do so now by running the
C:\workbook\ex12_1>ant dropdb Buildfile: build.xml prepare: compile: dropdb: [java] Looking up home interfaces.. [java] Dropping database table... BUILD SUCCESSFUL
Then re-create the
PAYMENT database table by
C:\workbook\ex12_1>ant createdb Buildfile: build.xml prepare: compile: ejbjar: createdb: [java] Looking up home interfaces.. [java] Creating database table...
On the JBoss console, the following lines are displayed:
