flex4 调整java ee 练习——HelloWorld

flex4 整合java ee 练习——HelloWorld

一、修改 web.xml文件，添加如下代码

<display-name>BlazeDS</display-name>    <description>BlazeDS Application</description>    <!-- Http Flex Session attribute and binding listener support -->    <listener>        <listener-class>flex.messaging.HttpFlexSession</listener-class>    </listener>    <!-- MessageBroker Servlet -->    <servlet>        <servlet-name>MessageBrokerServlet</servlet-name>        <display-name>MessageBrokerServlet</display-name>        <servlet-class>flex.messaging.MessageBrokerServlet</servlet-class>        <init-param>            <param-name>services.configuration.file</param-name>            <param-value>/WEB-INF/flex/services-config.xml</param-value>       </init-param>        <load-on-startup>1</load-on-startup>    </servlet>    <!-- begin rds    <servlet>        <servlet-name>RDSDispatchServlet</servlet-name><display-name>RDSDispatchServlet</display-name>        <servlet-class>flex.rds.server.servlet.FrontEndServlet</servlet-class><init-param><param-name>useAppserverSecurity</param-name><param-value>true</param-value></init-param>                <load-on-startup>10</load-on-startup>    </servlet>    <servlet-mapping id="RDS_DISPATCH_MAPPING">        <servlet-name>RDSDispatchServlet</servlet-name>        <url-pattern>/CFIDE/main/ide.cfm</url-pattern>    </servlet-mapping>end rds -->    <servlet-mapping>        <servlet-name>MessageBrokerServlet</servlet-name>        <url-pattern>/messagebroker/*</url-pattern>    </servlet-mapping>    <welcome-file-list>        <welcome-file>index.html</welcome-file>        <welcome-file>index.htm</welcome-file>    </welcome-file-list>    <!-- for WebSphere deployment, please uncomment -->    <!--    <resource-ref>        <description>Flex Messaging WorkManager</description>        <res-ref-name>wm/MessagingWorkManager</res-ref-name>        <res-type>com.ibm.websphere.asynchbeans.WorkManager</res-type>        <res-auth>Container</res-auth>        <res-sharing-scope>Shareable</res-sharing-scope>    </resource-ref>    -->

二、添加类库和配置文件，放在WEB-INF下面，如图：附件

?

三、新建java类：HelloWorld.java

package hello;public class HelloWorld {    public HelloWorld(){}       public String getHelloWorld(String str){        System.out.println("Hello World!  "+str);        return "Hello  "+str;    }}

?

?

四、修改remote-config.xml文件，添加内容如下：

<destination id="helloWorld">        <properties>            <source>hello.HelloWorld</source>        </properties></destination>

?

五、新建MXML应用程序 TestHelloWorld.xml

<?xml version="1.0" encoding="utf-8"?><s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"    xmlns:s="library://ns.adobe.com/flex/spark"    xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"><s:layout><s:BasicLayout/></s:layout><fx:Declarations><!-- 将非可视元素（例如服务、值对象）放在此处 --><mx:RemoteObject id="remoteObject" destination="helloWorld"  result="resultHandler(event)" fault="faultHandler(event)"></mx:RemoteObject></fx:Declarations><fx:Script><![CDATA[import mx.controls.Alert;import mx.rpc.events.FaultEvent;import mx.rpc.events.ResultEvent;private function resultHandler(event:ResultEvent):void{Alert.show(event.result.toString(),"提示");}private function faultHandler(event:FaultEvent):void{Alert.show(event.fault.toString(),"提示");}private function sendStr():void{remoteObject.getHelloWorld(str.text);//Alert.show(str.text);}]]></fx:Script><s:Label id="Label" text="请输入字符串" x="195" y="197"/><s:TextInput id="str"  x="279" y="188"/><s:Button label="发送" click="sendStr()" x="435" y="189"/></s:Application>
