基于Tomcat容器的ActiveMQ简单实例

      在tomcat中配置ConnectionFactory和ActiveMQQueue,通过JNDI方式实现ActiveMQ。因为JNDI配置在

tomcat容器中所以必须通过jsp访问tomcat容器。

首先在在tomcat的lib目录添加如下jar文件。

<classpathentry kind="lib" path="src/activemq-all-5.5.0.jar"/>
	<classpathentry kind="lib" path="src/slf4j-api-1.5.2-sources.jar"/>
	<classpathentry kind="lib" path="src/slf4j-api-1.5.2.jar"/>
	<classpathentry kind="lib" path="src/slf4j-simple-1.5.2.jar"/>
	<classpathentry kind="lib" path="src/log4j-1.2.8.jar"/>
	<classpathentry kind="lib" path="src/commons-dbcp-1.4.jar"/>
	<classpathentry kind="lib" path="src/commons-pool-1.5.4.jar"/>
	<classpathentry kind="lib" path="src/commons-collections-3.2.1.jar"/>
	<classpathentry kind="lib" path="src/xbean-server-3.3.jar"/>

 

在Tomcat的conf目录下的context.xml配置中添加如下：

<Resource name="jms/ConnectionFactory"  
				auth="Container"  
				type="org.apache.activemq.ActiveMQConnectionFactory"
				description="JMS Connection Factory"
				factory="org.apache.activemq.jndi.JNDIReferenceFactory"
				brokerURL="tcp://localhost:61616"
				brokerName="LocalActiveMQBroker" />
				
	<Resource name="jms/Queue"  
				auth="Container"  
				type="org.apache.activemq.command.ActiveMQQueue"
				description="My Queue"
				factory="org.apache.activemq.jndi.JNDIReferenceFactory"
				physicalName="TomcatQueue" />	

 配置如下：

你好 请问你说的tomcat容器中所以必须通过jsp访问tomcat容器是什么意思呢？
因为在activemq官网上有介绍可以用ajax来传送消息，请问你知道这个是怎么实现的吗？

至于你说的Ajax发送消息是ajax调用activemq的js版本实现的,在网上查一下,官方有文档

你看一下xml配置
<bean  id="tomcatQueue" class="org.springframework.jndi.JndiObjectFactoryBean">  
     <property name="jndiName" value="java:comp/env/jms/Queue"></property>  
</bean>  
中JNDI依赖于tomcat容器信息.
