The `ejb-in-ear` quickstart demonstrates how to deploy an EAR archive that contains a *JSF* WAR and an EJB JAR.

== What is it?

The `ejb-in-ear` quickstart demonstrates the deployment of an EAR artifact to {productNameFull}. The EAR contains a JSF WAR and an EJB JAR.

This example consists of the following Maven projects, each with a shared parent.

[cols="30%,70%",options="headers"]
|===
|Project |Description

| `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, using the following workflow.

. A JSF page asks for a user name.
. On clicking *Greet*, the name is sent to a managed bean named `Greeter`.
. On setting the name, the `Greeter` invokes the `GreeterEJB`, which was injected to the managed bean. Notice the field is 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.

. Right-click on the *{artifactId}-ear* subproject, and choose *Run As* -> *Run on Server*.
. Choose the server and click *Finish*.
. This starts the server, deploys the application, and opens a browser window that accesses the running application.
. To undeploy the project, right-click on the *{artifactId}-ear* project and choose *Run As* -> *Maven build*. Enter `wildfly:undeploy` for the *Goals* and click *Run*.
