本文介绍如何使用Flex的Consumer和Producer组件与Java消息服务(JMS)进行集成，实现客户端与服务器之间的消息传递。通过配置message-config.xml文件，支持本地及远程JMS服务器，并详细展示了配置示例。

1、demo.mxml:通过Consumer订阅，Producer发送消息

<mx:ChannelSet id="cs">  
        <mx:AMFChannel url="http://localhost:8080/JmsMessageDemo/messagebroker/amfpolling"/> 
    </mx:ChannelSet> 
    
	<mx:Consumer id="consumer" destination="chat-topic-jms" channelSet="{cs}"
		message="messageHandler(event)" fault="messageFault(event)"/>
	
	<mx:Producer id="producer"  channelSet="{cs}"
		destination="chat-topic-jms"
		acknowledge="acknowledgeHandler(event)"
		fault="faultHandler(event)"/>

注：这里指定channelset是因为我建的工程中services-config.xml中的配置为

<channel-definition id="my-polling-amf" class="mx.messaging.channels.AMFChannel">
            <endpoint url="http://{server.name}:{server.port}/{context.root}/messagebroker/amfpolling" class="flex.messaging.endpoints.AMFEndpoint"/>
            <properties>
                <polling-enabled>true</polling-enabled>
                <polling-interval-seconds>4</polling-interval-seconds>
            </properties>
        </channel-definition>

运行程序时endpoint尽然变成http://{server.name}:{server.port}/webRoot/messagebroker/amfpolling(context.root应该是工程名字才对，这可能是我创建工程时设置的问题)，所有要在consumer和producer中指定channelset

2、message-config.xml的配置（jms在本机）：

<adapters>
		<adapter-definition id="actionscript" class="flex.messaging.services.messaging.adapters.ActionScriptAdapter" default="true" />
		<adapter-definition id="jms" class="flex.messaging.services.messaging.adapters.JMSAdapter" />
	</adapters>

	<default-channels>
		<channel ref="my-polling-amf" />
	</default-channels>

<destination id="chat-topic-jms">
	<properties>
		<jms>
			<destination-type>Topic</destination-type>
			<message-type>javax.jms.TextMessage</message-type>
			<connection-factory>jms/flex/TopicConnectionFactory</connection-factory>
			<destination-jndi-name>jms/topic/flex/simpletopic</destination-jndi-name>
			<delivery-mode>NON_PERSISTENT</delivery-mode>
			<message-priority>DEFAULT_PRIORITY</message-priority>
			<preserve-jms-headers>"true"</preserve-jms-headers>
			<acknowledge-mode>AUTO_ACKNOWLEDGE</acknowledge-mode>
<!--			<connection-credentials username="guest" password="guest"/>-->
			<max-producers>1</max-producers>
		</jms>
	</properties>
	<adapter ref="jms"/>
</destination>

jms/flex/TopicConnectionFactory：jms的factory的JNDI名字

jms/topic/flex/simpletopic：jms的resource的JNDI名字

3、如果jms在远程，那么message-config.xml的配置：

<adapters>
		<adapter-definition id="actionscript" class="flex.messaging.services.messaging.adapters.ActionScriptAdapter" default="true" />
		<adapter-definition id="jms" class="flex.messaging.services.messaging.adapters.JMSAdapter" />
	</adapters>

	<default-channels>
		<channel ref="my-polling-amf" />
	</default-channels>

<destination id="chat-topic-jms">
 <properties>
  <jms>
   <destination-type>Topic</destination-type>
   <message-type>javax.jms.TextMessage</message-type>
   <connection-factory>jms/flex/TopicConnectionFactory</connection-factory>
   <destination-jndi-name>jms/topic/flex/simpletopic</destination-jndi-name>
   <delivery-mode>NON_PERSISTENT</delivery-mode>
   <message-priority>DEFAULT_PRIORITY</message-priority>
   <preserve-jms-headers>"true"</preserve-jms-headers>
   <acknowledge-mode>AUTO_ACKNOWLEDGE</acknowledge-mode>
<!--   <connection-credentials username="guest" password="guest"/>-->
   <max-producers>1</max-producers>
   <!-- (Optional) JNDI environment. Use when using JMS on a remote JNDI server. -->
   
   <initial-context-environment>
    <property>
     <name>java.naming.factory.initial</name>
     <value>com.sun.enterprise.naming.SerialInitContextFactory</value>
    </property>
    <property>
     <name>java.naming.factory.url.pkgs</name>
     <value>com.sun.enterprise.naming</value>
    </property>
    <property>
     <name>java.naming.factory.state</name>
     <value>com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl</value>
    </property>
    <property>
     <name>org.omg.CORBA.ORBInitialHost</name>
     <value>{远程ip}</value>
    </property>
    <property>
     <name>org.omg.CORBA.ORBInitialPort</name>
     <value>3700</value>
    </property>
   </initial-context-environment>
  </jms>
 </properties>
 <adapter ref="jms"/>
</destination>

节点initial-context-environment中的属性为JNDI lookup时需要设置的一些context属性（我用的是glassfish）
