The Phone Book Bean Example

...

And, as usual there is an empty constructor for the Entity Bean

...

...

MyPhonebookLocal.java is the business interface that drives the above mentioned Entity Bean.

...

...

MyPhonebookBean.java is where the implementation of the local (and if there is, a the remote) interface exists. To explain what the annotations in this Stateless Session Bean means I will enumerate them:

...

1. @Stateless - tells Geronimo that this is a stateless session bean
2. @PersistenceUnit - tells Geronimo to retrieve a persistence unit defined in the persistence.xml and place it in the EntityManagerFactory

   Note

   Note that PersistenceContext is used when you are directly obtaining a EntityManager. For an EntityManagerFactory use PersistenceUnit.

...

...

index.jsp is the JSP page that uses the EJB to access the database.

...

...

Deployment Plans

persistence.xml will specify the name of the PersistenceUnit. This name is used when referencing for the EntityManagerFactory. I have denoted it as PhonePU. I added an extra property called SynchronizeMappings so that the data in the database will not be overwritten.

...

...

Deployment Plan for the Application

plan.xml is generated by building the sample and can be found under ./myphonebook-jetty/target/resources/META-INF/plan.xml to deploy on jetty or ./myphonebook-tomcat/target/resources/META-INF/plan.xml to deploy on tomcat following a successful build of the sample. Shown below is the deployment plan for tomcat.

Source Code

...

for Sample

Please reference Samples General Information for information on obtaining and building the source for this and other samples.

You can checkout the source code of this sample from SVN:

svn checkout http://svn.apache.org/repos/asf/geronimo/samples/trunk/samples/myphonebook^{Image Removed}

Creating and Populating Database

The datasource necessary for this example can be installed using If you choose to install the sample as a plugin it is not necessary to create or populate the database as this will be completed as part of the plugin installation. However, if you prefer to deploy the sample using the generated ear you must first install the sample-datasource plugin. Use You can use either the administration console to first install this pluginplugin portlet or the command line install-plugin to install the sample-datasource. When you later deploy the sample application the necessary database table and entries will be createdthe DBInitialization GBean included in the deployment plan will populate the database.

Building

Use a command prompt to navigate into the myphonebook directory and just give mvn install followed by mvn site command to build. It will create the myphonebook-ear-2.01-SNAPSHOT.ear under the myphonebook folder. Now, you are ready to deploy myphonebook application in the Geronimo Application server using either the plugins generated for tomcat and jetty or the deployment plan that was generated and the ear.

Deploying the Application

...

As previously mentioned, there are two different ways to deploy the sample application - deployment as a plugin or deployment using the ear and plan.

To deploy the sample as a plugin you should do the following using the Geronimo administration console:

1. Scroll down to Plugins from the Console Navigation panel.
2. Select Update Repository List to get the repository for the server release in use added
3. Select the repository for the geronimo release in use and the click on Show Plugins in selected repository
4. Scroll down to the myphonebook plugin for your Geronimo configuration (Jetty or Tomcat) and then select install

To deploy the sample using the ear do the following using the Geronimo administration console:

1. First, install the sample-datasource plugin. You can do this as follows:
   1. Scroll down to Plugins from the Console Navigation panel.
   2. Select Update Repository List to get the repository for the server release in use added
   3. Select the repository for the geronimo release in use and the click on Show Plugins in selected repository
   4. Scroll down to the myphonebook plugin for your Geronimo configuration (Jetty or Tomcat) and then select install
2. Scroll down to Deploy New from the Console Navigation panel.
3. Load myphonebook-ear-2.1-SNAPSHOT.ear from ./myphonebook-ear/target/ in to the Archive input box.
4. Load plan.xml from ./myphonebook-jetty/target/resources/META-INF/ or ./myphonebook-tomcat/target/resources/META-INF/ depending on the target server (jetty or tomcat).
5. Press Install button to deploy application in the server.
