What is it?

This example demonstrates the use of OSGi in Red Hat JBoss Enterprise Application Platform.

There is a tutorial for this quickstart in the Getting Started Developing Applications Guide.

System requirements

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.

Configure Maven

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

Start the JBoss Server with the OSGi 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 OSGi profile:

         For Linux:   JBOSS_HOME/bin/standalone.sh  -c standalone-osgi.xml
         For Windows: JBOSS_HOME\bin\standalone.bat -c standalone-osgi.xml
    

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 install jboss-as:deploy
    
  4. This will deploy and start the OSGi bundle.

Investigate the Server Console Output

Look in the JBoss Application Server console or Server log and you should see the following message:

`Hello World!!`

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
