helloworld


    Body
    The helloworld quickstart demonstrates the use of CDI and Servlet 3 and is a good starting point to verify JBoss EAP is configured correctly.

    What is it?

    The helloworld quickstart demonstrates the use of CDI and Servlet 3 in JBoss Enterprise Application Platform Server 7.2.

    System Requirements

    The application this project produces is designed to be run on JBoss Enterprise Application Platform Server 7.2 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 to Build and Deploy the Quickstarts to make sure you are configured correctly for testing the quickstarts.

    Use of EAP_HOME

    In the following instructions, replace EAP_HOME with the actual path to your JBoss EAP installation. The installation path is described in detail here: Use of EAP_HOME and JBOSS_HOME Variables.

    Start the JBoss EAP Standalone Server

    1. Open a terminal and navigate to the root of the JBoss EAP directory.

    2. Start the JBoss EAP server with the default profile by typing the following command.

      $ EAP_HOME/bin/standalone.sh 
      Note
      For Windows, use the EAP_HOME\bin\standalone.bat script.

    Build and Deploy the Quickstart

    1. Make sure you start the JBoss EAP server as described above.

    2. Open a terminal and navigate to the root directory of this quickstart.

    3. Type the following command to build the artifacts.

      $ mvn clean package wildfly:deploy

    This deploys the helloworld/target/helloworld.war to the running instance of the server.

    You should see a message in the server log indicating that the archive deployed successfully.

    Access the Application

    The application will be running at the following URL: http://localhost:8080/helloworld/.

    Undeploy the Quickstart

    When you are finished testing the quickstart, follow these steps to undeploy the archive.

    1. Make sure you start the JBoss EAP server as described above.

    2. Open a terminal and navigate to the root directory of this quickstart.

    3. Type this command to undeploy the archive:

      $ mvn wildfly:undeploy

    Run the Quickstart in Red Hat JBoss Developer Studio or Eclipse

    You can also start the server and deploy the quickstarts or run the Arquillian tests in Red Hat JBoss Developer Studio or from Eclipse using JBoss tools. For general information about how to import a quickstart, add a JBoss EAP server, and build and deploy a quickstart, see Use JBoss Developer Studio or Eclipse to Run the Quickstarts.

    Debug the Application

    If you want to debug the source code of any library in the project, run the following command to pull the source into your local repository. The IDE should then detect it.

    $ mvn dependency:sources
