The quickstart name doesn't match the quickstart folder name. This name should probably be deltaspike-beanmanagerprovider to match the folder name. Also, the "jboss-as" prefix is only used in the URL to access the application. :-)

Summary: Shows how to use DeltaSpike BeanManagerProvider to access CDI in a EntityListener
Prerequisites:
Target Product: WFK

What is it?
-----------

This project demonstrates the use of DeltaSpike's BeanManagerProvider.

`BeanmanagerProvider` provides access to the `BeanManager` by registering the current `BeanManager` during the startup. This is really handy if you like to access CDI functionality from places where no CDI based injection is available. If a simple but manual bean-lookup is needed, it's easier to use the `BeanProvider` instead.

This projects uses an EntityListener to create audit records. EntityListeners aren't managed by CDI, so you can't inject dependencies. In this project we used `BeanManagerProvider` to get a reference to a Stateless EJB that is responsible to persist the audit records.


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](../README.md#mavenconfiguration) before testing the quickstarts.


Start JBoss Enterprise Application Platform 6 or JBoss AS 7
-------------------------

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](../README.md#buildanddeploy) 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-deltaspike-beanmanagerprovider.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/jboss-as-deltaspike-beanmanagerprovider>

You are presented with a simple form to insert, edit, or remove contacts.

- To insert a new contact, click the `New Contact` button. Complete the form fields and then click the `Save` button.
- To modify an existing contact, find the name in the *All Contacts* table and click the `Select for edit` button. The *Contacts* form fields are populated with the contact data. Modify the data and then click the `Save` button.
- To remove a contact, find the name in the *All Contacts* table and click the `Remove` button. A dialog appears asking 'Do you want to remove this record?'. Click the `OK` button to remove the contact.

When you insert a contact, notice that both the *All Contacts* and *Audit Records* tables are updated.
When you edit a contact, notice that the *Audit Records* table is updated with the new contact data.

Continue to insert, edit, or remove contacts to see registration of audit records.

_NOTE: To fire the update audit, you must change one of the contact fields_


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](../README.md#useeclipse)

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
