--------------------------------------------------------------
The *JBoss Central* editor includes several quickstarts that provide a quick run-through of Java EE 6 features.
The quickstarts are based on amazing Pete Muir's JBoss AS7 quickstarts -  https://docs.jboss.org/author/display/AS7/Getting+Started+Developing+Applications+Guide JBoss AS 7.0 - Getting Started Developing Applications Guide
and are adapted to work with Eclipse/JBoss Tools. 
This blog guides you how to install *JBoss Tools 3.3* and start work with Java EE 6 using these tutorials. 

h4. Installing JBoss Tools 3.3

 In order to install *JBoss Tools 3.3*, you need to perform the following steps: 
* install  http://www.eclipse.org/downloads/packages/eclipse-ide-java-developers/indigosr1 Eclipse Java EE IDE for Web Developers  Download the appropriate archive for your OS, unpack it and start Eclipse.   
*   Call *Help>Install New Software*..., click the *Add* button and enter the following update site:

* select the *Abridged JBoss Tools 3.3* category https://community.jboss.org/servlet/JiveServlet/showImage/38-4362-17648/jeeblog2.png  https://community.jboss.org/servlet/JiveServlet/downloadImage/38-4362-17648/450-382/jeeblog2.png 
  Click *Next*, *Next*, check "*I accept the terms of the license agreements*" and click *Finish*.

* Wait for Eclipse to download and install the *JBoss Tools 3.3*.   
* Restart Eclipse when required.    

You have installed *JBoss Tools 3.3*.

h4. JBoss Quickstarts (JBoss Central)

After Eclipse restarts, you will get the *JBoss Central* editor.

Expand the *JBoss Quickstart* widget in the *Project Examples* section

 https://community.jboss.org/servlet/JiveServlet/showImage/38-4362-17599/jeeblog4.png  https://community.jboss.org/servlet/JiveServlet/downloadImage/38-4362-17599/310-152/jeeblog4.png 
The *helloworld, numberguess, login and kitchensink* quickstarts will guide you through creating a Java EE 6 application.
Here I will describe to you how to create the *helloworld* application.  The rest of the applications are used in a similar way, but they introduce new concepts as shown in the following figures:

 https://community.jboss.org/servlet/JiveServlet/showImage/38-4362-17602/jeeblog7.png  https://community.jboss.org/servlet/JiveServlet/downloadImage/38-4362-17602/310-172/jeeblog7.png 
 https://community.jboss.org/servlet/JiveServlet/showImage/38-4362-17603/jeeblog8.png  https://community.jboss.org/servlet/JiveServlet/downloadImage/38-4362-17603/310-145/jeeblog8.png 
The *HTML5* is a template project that doesn't include any cheat sheet.

h4. Helloworld quickstart

In order to create the *helloworld* Java EE 6 application, you have to do the following: 

1. click the *Helloworld* project example in the *JBoss Central* editor https://community.jboss.org/servlet/JiveServlet/showImage/38-4362-17605/jeeblog9.png  https://community.jboss.org/servlet/JiveServlet/downloadImage/38-4362-17605/310-182/jeeblog9.png 
2. *JBoss Tools* will warn you that you have to install JBoss AS 7.0 or 7.1 in order to create, deploy and run this application. 
If you have already installed and configured JBoss AS 7.x, you won't see any requirement and will be able to skip to the step *3*.              
*  If you have already downloaded JBoss AS 7.x, you will be able to configure it using the *Install* button. https://community.jboss.org/servlet/JiveServlet/showImage/38-4362-17606/jeeblog10.png  https://community.jboss.org/servlet/JiveServlet/downloadImage/38-4362-17606/450-495/jeeblog10.png 
Add the directory where you downloaded your JBoss AS and *JBoss Tools* will configure a JBoss AS 7.x server for you. 

* If you don't have any JBoss AS 7.x server, click the *Download and Install...* button and *JBoss Tools* will, for you, download JBoss AS 7.0.2
 https://community.jboss.org/servlet/JiveServlet/showImage/38-4362-17607/jeeblog11.png  https://community.jboss.org/servlet/JiveServlet/downloadImage/38-4362-17607/450-138/jeeblog11.png 
 https://community.jboss.org/servlet/JiveServlet/showImage/38-4362-17608/jeeblog12.png  https://community.jboss.org/servlet/JiveServlet/downloadImage/38-4362-17608/310-123/jeeblog12.png 


3. When the JBoss AS is installed and configured, you will get the following dialog: https://community.jboss.org/servlet/JiveServlet/showImage/38-4362-17609/jeeblog13.png  https://community.jboss.org/servlet/JiveServlet/downloadImage/38-4362-17609/310-158/jeeblog13.png 
Click the *Start* button. 
The *jboss-as-helloworld* project will be imported and you will get the *helloworld* cheat sheet that will help you to review the application. 
 https://community.jboss.org/servlet/JiveServlet/showImage/38-4362-17610/jeeblog14.png  https://community.jboss.org/servlet/JiveServlet/downloadImage/38-4362-17610/252-192/jeeblog14.png 
 https://community.jboss.org/servlet/JiveServlet/showImage/38-4362-17611/jeeblog15.png  https://community.jboss.org/servlet/JiveServlet/downloadImage/38-4362-17611/310-355/jeeblog15.png 
Read the introduction to learn how the application works and click *Click to Begin*. 
The following screen will appear: 
 https://community.jboss.org/servlet/JiveServlet/showImage/38-4362-17612/jeeblog16.png  https://community.jboss.org/servlet/JiveServlet/downloadImage/38-4362-17612/310-423/jeeblog16.png 
After reading a detailed description, click *Click when complete*. 
 https://community.jboss.org/servlet/JiveServlet/showImage/38-4362-17613/jeeblog17.png  https://community.jboss.org/servlet/JiveServlet/downloadImage/38-4362-17613/310-426/jeeblog17.png 
The *HelloWorldServlet.java* section explains the *HelloWorld* servlet in detail.  When clicking the action, the cheat sheet will open the appropriate section of the code. 
 https://community.jboss.org/servlet/JiveServlet/showImage/38-4362-17614/jeeblog18.png  https://community.jboss.org/servlet/JiveServlet/downloadImage/38-4362-17614/450-253/jeeblog18.png 
Run or skip all the actions in the *HelloWorldServlet.java* section. You will get the *HelloService.java* section. 
 https://community.jboss.org/servlet/JiveServlet/showImage/38-4362-17615/jeeblog19.png  https://community.jboss.org/servlet/JiveServlet/downloadImage/38-4362-17615/310-407/jeeblog19.png 
Click *Click to perform*. The following screen will show up: 
 https://community.jboss.org/servlet/JiveServlet/showImage/38-4362-17616/jeeblog20.png  https://community.jboss.org/servlet/JiveServlet/downloadImage/38-4362-17616/450-217/jeeblog20.png 
That's it. You are ready to deploy and run the application on the JBoss AS 7 server you previously installed and configured. 
Click *Click to perform*
 https://community.jboss.org/servlet/JiveServlet/showImage/38-4362-17617/jeeblog21.png  https://community.jboss.org/servlet/JiveServlet/downloadImage/38-4362-17617/310-412/jeeblog21.png 
Click *Next*
 https://community.jboss.org/servlet/JiveServlet/showImage/38-4362-17618/jeeblog22.png  https://community.jboss.org/servlet/JiveServlet/downloadImage/38-4362-17618/310-412/jeeblog22.png 
Finally, click the *Finish* button. 
The cheat sheet will start the server, deploy the application and open it in a browser.

In a similar way, you will be able to create and review the *numberguess*, *login* and *kitchensink* applications. *Kitchensink* is an especially interesting application. In addition to explaining many Java EE 6 features (CDI, JSF, EJB, JTA, Bean Validation, JAX-RS, Arquillian), it automatically runs an Arquillian test and enables you to create your starting project. 
Some advanced Java EE developers might also be interested in reviewing this application.
