j2ee整合flex的小實例

總結一

下flex+BlazeDS整合j2ee開發環境的配置過程：

1.從http://opensource.adobe.com/wiki/display/blazeds/BlazeDS/ 下載BlazeDS
  
2.新建一個web project 名爲：flexDemo

3.解壓BlazeDS.war到%TOMCAT_HOME%/webapps目錄下文件名爲blazeds內包涵了WEB-INF和META－INF文件夾

4.在flexDemo/src目錄下新建類HelloWorld

package cn.riahome.java;

/**
* <p>功能:</p>
* <p>生成日期: 2008-10-13</p>
* <p>說明：</p>
* @author lipei_ma
* @version V1.0
* @修改日誌:
*/
public class HelloWorld {

    public HelloWorld() {
     }

    public String getHelloWorld(String name) {
        return "Hello World!"+name;
     }
}

package cn.riahome.java;

/**
 * <p>功能:</p>
 * <p>生成日期: 2008-10-13</p>
 * <p>說明：</p>
 * @author lipei_ma
 * @version V1.0
 * @修改日誌:
 */
public class HelloWorld {

 public HelloWorld() {
 }

 public String getHelloWorld(String name) {
  return "Hello World!"+name;
 }
}

5.部署 應用flexDemo到Tomcat服務器中，並啓動服務。








6.爲flexDemo添加blazeds支持： 將%TOMCAT_HOME%/webapps/BlazeDS/WEB-INF/lib目錄下面所有jar文件拷貝到 flexDemo 的webRoot/WEB-

INF/lib 目錄下. 將%TOMCAT_HOME%/webapps/blazeds/WEB-INF/flex 目錄拷貝到Demo的webContent/WEB-INF 下. 拷貝%TOMCAT_HOME%/webapps

/BlazeDS/WEB-INF/ 下的web.xml覆蓋flexDemo的 web.xml ,至此,我們的Demo已經具備了blazeds 的功能.



7.爲項目增加Flex支持，右鍵項目名稱，點擊Flex Project Nature/Add Flex Project Nature









8.編輯flexDemo.mxml

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
      <mx:RemoteObject id="say" destination="helloWorld">
      </mx:RemoteObject>
      <mx:Button x="335" y="80" label=" Click" click="remotingSayHello(event);"/>
      <mx:TextInput x="159" y="80" id="tiName"/>
      <mx:Label x="109" y="82" text="name:"/>
      <mx:Label text="{say.getHelloWorld.lastResult}" x="44" y="162" width="448" height="71" id="lblView" color="#FCEE09"

fontSize="20" fontWeight="bold" textDecoration="underline" fontStyle="normal"/>
      <mx:Script>
          <![CDATA[
             public function remotingSayHello(event:Event):void{
                  var iname:String=tiName.text;
                  say.getHelloWorld(iname);
              }
          ]]>
      </mx:Script>
</mx:Application>

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
     <mx:RemoteObject id="say" destination="helloWorld">           
     </mx:RemoteObject>
     <mx:Button x="335" y="80" label=" Click" click="remotingSayHello(event);"/>     
     <mx:TextInput x="159" y="80" id="tiName"/>     
     <mx:Label x="109" y="82" text="name:"/>     
     <mx:Label text="{say.getHelloWorld.lastResult}" x="44" y="162" width="448" height="71" id="lblView" color="#FCEE09" 

fontSize="20" fontWeight="bold" textDecoration="underline" fontStyle="normal"/>     
     <mx:Script>
      <![CDATA[
       public function remotingSayHello(event:Event):void{        
        var iname:String=tiName.text;          
        say.getHelloWorld(iname);          
       }
      ]]>
     </mx:Script> 
</mx:Application>

編輯WEB-INF/flex/remoting-config.xml文件

<destination id="helloWorld">
lt;properties>
<source>cn.riahome.java.HelloWorld</source>
lt;/properties>
   </destination>

<destination id="helloWorld">
  <properties>
   <source>cn.riahome.java.HelloWorld</source>
  </properties>
     </destination>

9.右鍵項目名稱，點擊properties/Flex Builder Path修改output folder URL,點擊properties/Flex Build Path修改Flex SDK Version







10.運行flexDemo.mxml即可
