Java 如何在ApacheTomee下配置ActiveMQ内存设置？

我在ApacheTomee下有一个嵌入式ActiveMQ。TomEE在一个名为TomEE.xml的文件中配置JMS，在我的例子中，它的配置如下

<Resource id="Default JMS Resource Adapter" type="ActiveMQResourceAdapter">
    BrokerXmlConfig = broker:(tcp://localhost:61616)?persistent=true
    ServerUrl = tcp://localhost:61616
    DataSource = MyDataSource
</Resource>

我错过了什么

更新-更多信息，然后

然后，我将绝对路径添加到activemq.xml文件中，因为我无法从eclipse内部使其工作（我知道，这可能更像是eclipse的错误）

然后我更改了一些无效的XML，例如

<!--             <destinationPolicy> -->
<!--                 <policyMap> -->
<!--                     <policyEntries> -->
<!--                         <policyEntry queue=">" producerFlowControl="false" prioritizedMessages="true" useCache="false" expireMessagesPeriod="0" queuePrefetch="1" /> -->
<!--                         <pendingQueuePolicy> -->
<!--                             <vmQueueCursor /> -->
<!--                         </pendingQueuePolicy> -->
<!--                     </policyEntries> -->
<!--                 </policyMap> -->
<!--             </destinationPolicy> -->

经过一些google，一些解决方案似乎在某种程度上与activemq无法加载XML有关（这是有道理的，因为XML是一项最新技术，发明于96年，大约20年前）

我很紧张。

我认为您的传输连接器配置应该如下所示：

<transportConnectors>
    <transportConnector name="tcp" uri="tcp://0.0.0.0:61616"/>
</transportConnectors>

有关接头，请参见。

就在那里。。。现在我得到的原因是：java.io.IOException:无法加载xbean工厂：（…）原因是：java.lang.ClassNotFoundException:org.apache.activemq.xbean.XBeanBrokerFactory您在使用maven吗？如果是，将

activemqspring

工件添加到依赖项列表中。如果没有，那么手动将activemq安装中的

activemq spring-.jar

添加到类路径中。是的，我已经解决了这个问题。。。我快到了。我不得不删除一些无效的XML，现在我只想设置jdbcPersistenceAdapter。还必须使用tomee.xml中的绝对路径。。。似乎很难配置应该是simpleBTW的东西，试图从eclipse内部运行。不是Mavena毕竟，我最后修复的是连接器，它使用的是tomee语法，而不是您正确指出的activemq语法。谢谢
