This example demonstrates the deployment of an EAR artifact. The EAR contains: JSF 2.0 WAR and an EJB 3.1 JAR.
The example is composed of three maven projects, each with a shared parent. The projects are as follows:
-
ejb
: This project contains the EJB code and can be built independently to produce the JAR archive. -
web
: This project contains the JSF pages and the managed bean. -
ear
: This project builds the EAR artifact and pulls in the ejb and web artifacts.
The root pom.xml
builds each of the subprojects in the above order and deploys the EAR archive to the server.
The example follows the common "Hello World" pattern. These are the steps that occur:
- A JSF page asks the user for their name.
- On clicking Greet, the name is sent to a managed bean named
Greeter
. - On setting the name, the
Greeter
invokes theGreeterEJB
, which was injected to the managed bean. Notice the field annotated with@EJB
. - The response from invoking the
GreeterEJB
is stored in a field (message) of the managed bean. - The managed bean is annotated as
@SessionScoped
, so the same managed bean instance is used for the entire session. This ensures that the message is available when the page reloads and is displayed to the user.
All you need to build this project is Java 6.0 (Java SDK 1.6) or better, Maven 3.0 or better.
The application this project produces is designed to be run on JBoss Enterprise Application Platform 6 or JBoss AS 7.
If you have not yet done so, you must Configure Maven before testing the quickstarts.
-
Open a command line and navigate to the root of the JBoss server directory.
-
The following shows the command line to start the server with the web profile:
For Linux: JBOSS_HOME/bin/standalone.sh For Windows: JBOSS_HOME\bin\standalone.bat
NOTE: The following build command assumes you have configured your Maven user settings. If you have not, you must include Maven setting arguments on the command line. See Build and Deploy the Quickstarts for complete instructions and additional options.
-
Make sure you have started the JBoss Server as described above.
-
Open a command line and navigate to the root directory of this quickstart.
-
Type this command to build and deploy the archive:
mvn clean package jboss-as:deploy
-
This will deploy
target/jboss-as-ejb-in-ear.ear
to the running instance of the server.
The application will be running at the following URL http://localhost:8080/jboss-as-ejb-in-ear.
Enter a name in the input field and click the Greet button to see the response.
-
Make sure you have started the JBoss Server as described above.
-
Open a command line and navigate to the root directory of this quickstart.
-
When you are finished testing, type this command to undeploy the archive:
mvn jboss-as:undeploy
You can also start the server and deploy the quickstarts from Eclipse using JBoss tools. For more information, see Use JBoss Developer Studio or Eclipse to Run the Quickstarts
If you want to debug the source code or look at the Javadocs of any library in the project, run either of the following commands to pull them into your local repository. The IDE should then detect them.
mvn dependency:sources
mvn dependency:resolve -Dclassifier=javadoc
