Java Enterprise Development - 2010 style

• You use the Java EE 6 Web Profile, and don´t need to pack your application into an EAR file.
• You code your domain model using a xml-less ORM fram framework (JPA). JPA actually makes sense and does what its supposed todo without fuss.
• You let your JPA implementation generate your database schema for you, which it does with surprising efficiency.
• You use modern, component-based view frameworks (like Facelets or Wicket) , and get by writing little or no XML for defining navigation (remember struts-config.xml?)
• You use annotations everywhere (your JPA entities, your Session Beans, your Servlets) and even start to forget XML syntax
• You don´t bother writing deployment descriptors for all your session beans. You just add one annotation to any POJO and it automatically gains EJB powers.
• You only write Remote Interfaces when you actually needs a component to be remotely accessible.
• You have no idea what CORBA is.
• You have a vague idea of what JNDI is, but you use dependency injection everywhere to get what you need.
• You develop using a lightweight application server (glassfish 3) that redeploys your application in seconds every time you make a change. Most of the time you don't even notice it.

{

public function People(iName:String, iGender:String, iMail:String)

{

name = iName;

gender = iGender;

}

public var name:String;

public var gender:String;

public var mail:String;




}

Add a new namespace for this AutoComplete Component

<?xml version="1.0" encoding="utf-8"?>

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"

xmlns:components="com.hillelcoren.components.*"

layout="absolute" >

</mx:Application>

Declare an ArrayCollection variable for AutoComplete component as its data provider.

And add value object, People, into this ArrayCollection as page load.

Use AutoComplete tag to realize auto complete function.

<?xml version="1.0" encoding="utf-8"?>

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"

xmlns:components="com.hillelcoren.components.*"

layout="absolute" initialize="init()">

<mx:Script>

<![CDATA[

import vo.People;

import mx.collections.ArrayCollection;




//declare an ArrayCollection as AutoComplete component's data provider

[Bindable]

private var peopleList:ArrayCollection = new ArrayCollection();




//set data into people list as page load

private function init():void{

peopleList.addItem(new People("Albert", "Male", "albert@gmail.com"));

peopleList.addItem(new People("Mandy", "Female", "mandy@gmail.com"));

peopleList.addItem(new People("Verio", "Male", "verio@gmail.com"));

peopleList.addItem(new People("Richard", "Male", "richard@gmail.com"));

peopleList.addItem(new People("Andrew", "Male", "andrew@gmail.com"));

}

]]>

</mx:Script>

<mx:HBox>

<mx:Label text="Name" />

<components:AutoComplete id="autoComplete" labelField="name" dataProvider="{peopleList}" />
