What is it?

Project stages provide a way to customize the implementation based on the type of deployment environment. For example, you may want to generate sample data for system testing, but not for production. You can create a bean that generates sample data and activate it only for project stage SystemTest

Besides custom project stages it's possible to use the following pre-defined project stages:

Furthermore, with @Exclude, it is possible to annotate beans which should be ignored by CDI, even if they are in a CDI enabled archive.

This project has a interface called MyBean that has 4 different implementations:

System requirements

All you need to build this project is Java 8.0 (Java SDK 1.8) or better, Maven 3.1 or better.

The application this project produces is designed to be run on WildFly 10.

Configure Maven

If you have not yet done so, you must Configure Maven before testing the quickstarts.

Start WildFly 10

  1. Open a command line and navigate to the root of the JBoss server directory.
  2. 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
    

Build and Deploy the Quickstart

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.

  1. Make sure you have started the JBoss Server as described above.
  2. Open a command line and navigate to the root directory of this quickstart.
  3. Type this command to build and deploy the archive:
    mvn clean package wildfly:deploy
    
  4. This will deploy target/wildfly-as-deltaspike-projectstage.war to the running instance of the server.

Access the application

Access the running application in a browser at the following URL: http://localhost:8080/wildfly-deltaspike-projectstage

You be presented with a simple page that shows the current project stage: Staging. You will se also the List of available CDI instances for MyBean table with two available implementations.

Edit the file src/main/resources/META-INF/apache-deltaspike.properties and change the org.apache.deltaspike.ProjectStage property to Development. Deploy the application again

    mvn clean package wildfly:deploy

Access the application again at the same URL: http://localhost:8080/wildfly-deltaspike-projectstage

Look at List of available CDI instances for MyBean table and realize that the available implementations has changed.

Undeploy the Archive

  1. Make sure you have started the JBoss Server as described above.
  2. Open a command line and navigate to the root directory of this quickstart.
  3. When you are finished testing, type this command to undeploy the archive:
    mvn wildfly:undeploy
    

Run the Quickstart in JBoss Developer Studio or Eclipse

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

Debug the Application

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
