Quickstarts

What is it?

This simple JSF 2.0 application shows how to use container defined modules to limit the size of the application package. It also shows how to use common versions of certain classes at runtime.

Applications must often depend on third-party libraries. By default, Java EE packages allow you to include dependencies in a deployable unit which can lead to uncontrolled growth of the deployable unit. This can be avoided by the use of container defined modules. A module is nothing more than a container managed binary dependency which is shared by all deployed applications. For more informatin on class loading and modules please refer to Class Loading in AS7.

This example is very simple. It declares dependency on the Apache Log4j module which allows it to use a custom logging framework. This is achieved with a simple addition to the xml file: src/main/webapp/WEB-INF/jboss-deployment-structure.xml. For more information about this file please refer to https://docs.jboss.org/author/display/AS7/Developer+Guide#DeveloperGuide-JBossDeploymentStructureFile or the product documentation.

System requirements

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.

Configure Maven

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

Start JBoss Enterprise Application Platform 6 or JBoss AS 7 with the Web Profile

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 jboss-as:deploy
   

4. This will deploy target/jboss-as-log4j.war to the running instance of the server.

Access the application

The application will be running at the following URL: http://localhost:8080/jboss-as-log4j/.

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 jboss-as: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
