      在tomcat中配置ConnectionFactory和ActiveMQQueue,通过JNDI方式实现ActiveMQ。因为JNDI配置在Java代码  
tomcat容器中所以必须通过jsp访问tomcat容器。  

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。

Java代码  
<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"/>  

<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：

Java代码  
<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" />      

<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：
