Question

问题陈述：我正在寻找帮助，将JMS连接工厂暴露给远程ActiveMQ实例（侦听tcp）作为Tomcat7中的容器资源，以便部署在Tomcat7上的Web应用程序可以访问它

我的配置：我在服务器上运行了Tomee和Tomcat7实例。 Tomee是ActiveMQ的主机，代理配置为侦听tcp wireformat连接（下面的tomee.xml）：

 <?xml version="1.0" encoding="UTF-8"?>
 <tomee>
  <!-- see http://tomee.apache.org/containers-and-resources.html -->
    <Resource id="MyJmsResourceAdapter" type="ActiveMQResourceAdapter">
        BrokerXmlConfig =  broker:(tcp://10.173.80.42:61619)
        ServerUrl       =  tcp://10.173.80.42:61619
    </Resource>

    <Resource id="jms/ConnectionFactory" type="javax.jms.ConnectionFactory">
        ResourceAdapter = MyJmsResourceAdapter
    </Resource>

    <Container id="MyJmsMdbContainer" type="MESSAGE">
        ResourceAdapter = MyJmsResourceAdapter
    </Container>

   <Resource id="myqueue" type="javax.jms.Queue"/>


  <!-- activate next line to be able to deploy applications in apps -->
  <Deployments dir="apps" />
</tomee>

在我的Tomcat7实例中，我将server.xml配置为：

<Resource name="jms/ConnectionFactory"
          auth="Container"
          type="org.apache.activemq.ActiveMQConnectionFactory"
          description="JMS Connection Factory"
          factory="org.apache.activemq.jndi.JNDIReferenceFactory"
          brokerURL="tcp://10.173.80.42:61619?soTimeout=60000"
          brokerName="ActiveMQStageBroker"
          useEmbeddedBroker="false" />

<Resource name="myQueue"
          auth="Container"
          type="org.apache.activemq.command.ActiveMQQueue"
          proxy-interface="javax.jms.Queue"
          description="My Queue"
          factory="org.apache.activemq.jndi.JNDIReferenceFactory"
          physicalName="myQueue" />

我已将activemq-all-5.12.0.jar放在Tomcat7共享库文件夹中。我还在Web应用程序META-INF文件夹下的context.xml文件中创建了相关的引用，并在web.xml中创建了一个额外的度量资源-ref（在这里基本上抓住了吸管）

我的观察：当我启动触发与ActiveMQ通信的操作时，我在日志文件中看到以下条目：

另外，当我查看我的队列的EnqueueCount和DequeueCount时，我发现它们没有改变。

由于日志表明我的Tomcat7容器实际上从远程实例接收了信息（参考“Received Wireformat：...”），因此可以传达这两个实例。但为什么我无法发送数据？

附录：部署在承载ActiveMQ的Tomee实例中的相同Web应用程序可以与队列无缝通信。

感谢任何关于我可能做错的想法，或者我可以在Tomee和Tomcat7端尝试的选项。

提前致谢！

Answer 1

在花费了不少时间试图让上述配置工作之后，原来是：

JNDI查找问题;
由记录异常的开发人员加入在调试级别，而不是错误级别（谢谢男人！）。

无论如何，所有这些都排序了，这就是我找到的：

上面提到的配置工作正常，ActiveMQ配置为作为Tomee容器的一部分运行，并且Tomcat7上的Connection代理作为全局共享资源暴露给部署在其中的WebApps（知道你的JNDI！）。 p>
我也可以使用@ JonathanS.Fisher建议的配置。我能够将ActiveMQ作为独立实例启动，并将我的应用程序托管在Tomcat7和Tomee上。

希望这有助于任何陷入类似情况的人。
