Summary: The ejb-in-ear
quickstart demonstrates how to deploy an EAR archive that contains a JSF WAR and an EJB JAR.
Target Product: WildFly
Source: https://github.com/wildfly/quickstart/
The ejb-in-ear
quickstart demonstrates the deployment of an EAR artifact to WildFly Application Server. The EAR contains: JSF WAR and an EJB 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:
Greeter
.Greeter
invokes the GreeterEJB
, which was injected to the managed bean. Notice the field annotated with @EJB
.GreeterEJB
is stored in a field (message) of the managed bean.@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.The application this project produces is designed to be run on WildFly Application Server 11 or later.
All you need to build this project is Java 8.0 (Java SDK 1.8) or later and Maven 3.3.1 or later. See Configure Maven for WildFly 11 to make sure you are configured correctly for testing the quickstarts.
In the following instructions, replace WILDFLY_HOME
with the actual path to your WildFly installation. The installation path is described in detail here: Use of WILDFLY_HOME and JBOSS_HOME Variables.
For Linux: WILDFLY_HOME/bin/standalone.sh
For Windows: WILDFLY_HOME\bin\standalone.bat
mvn clean install wildfly:deploy
This will deploy ear/target/ejb-in-ear.ear
to the running instance of the server.
The application will be running at the following URL http://localhost:8080/ejb-in-ear/.
Enter a name in the input field and click the Greet button to see the response.
mvn wildfly:undeploy
You can also start the server and deploy the quickstarts or run the Arquillian tests from Eclipse using JBoss tools. For general information about how to import a quickstart, add a WildFly server, and build and deploy a quickstart, see Use JBoss Developer Studio or Eclipse to Run the Quickstarts.
For this quickstart, follow the special instructions to build Quickstarts Containing an EAR.
