This quickstart demonstrates the use of an EJB 3.1 Singleton Bean in 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.
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.
The following shows the command line to start the server:
For Linux: JBOSS_HOME/bin/standalone.sh For Windows: JBOSS_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-helloworld-singleton.warto the running instance of the server.
The application will be running at the following URL: http://localhost:8080/jboss-helloworld-singleton.
This example demonstrates a singleton session bean that maintains state information for 2 variables: "Increment A" and "Increment B".
A counter is incremented when you click on the link to the variable name. If you close and restart your browser, or if you have multiple browsers, you can see that the counter always increments the last value. These values are maintained until you restart the server.
To test the singleton bean, click on either "Increment A" or "Increment B". The result page will give you the current value of the variable.
When you are finished testing, type this command to undeploy the archive:
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
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
