log4j quickstart is a simple JSF 2.1 application that shows how to use container defined modules to limit the size of the application package in Red Hat JBoss Enterprise Application Platform. 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 "About Modules and the New Modular Class Loading System used in JBoss EAP 6" in the Development Guide for Red Hat JBoss Enterprise Application Platform.
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 the the Development Guide for Red Hat JBoss Enterprise Application Platform.
The application this project produces is designed to be run on Red Hat JBoss Enterprise Application Platform 6.1 or later.
All you need to build this project is Java 6.0 (Java SDK 1.6) or later, Maven 3.0 or later.
If you have not yet done so, you must Configure Maven before testing the quickstarts.
In the following instructions, replace
EAP_HOME with the actual path to your JBoss EAP 6 installation. The installation path is described in detail here: Use of EAP_HOME and JBOSS_HOME Variables.
The following shows the command line to start the server:
For Linux: EAP_HOME/bin/standalone.sh For Windows: EAP_HOME\bin\standalone.bat
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.
Type this command to build and deploy the archive:
mvn clean install jboss-as:deploy
target/jboss-log4j.warto the running instance of the server.
The application will be running at the following URL: http://localhost:8080/jboss-log4j/.
When you are finished testing, type this command to undeploy the archive:
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 JBoss EAP server, and build and deploy a quickstart, see Use JBoss Developer Studio or Eclipse to Run the Quickstarts
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.
