Mule - 找不到 org.apache.activemq 类型

Question

我正在使用Mule Studio 3.4，想尝试使用Active Mq。我知道 ActiveMq 嵌入在 Mule 中，所以没有必要在类路径上添加 jar，顺便说一下，在类路径上找不到 activeMq 类。我错在哪里？这里是我的配置（从 http://www.mulesoft.org/mule-activemq-integration-examples 复制）：

</mule>

错误是"无法在项目的构建路径上找到类型 org.apache.activemq.broker.region.policy.IndividualDeadLetterStrategy..."和类似的其他。谢谢！

Mule 不捆绑 activemq jar，也不捆绑任何 JMS 代理的 jar，因此，如果您希望容器提供它，则需要手动将其添加到您的项目或${studio.home}/plugins/org.mule.tooling.server.${mule.version}_${mule.version}.${time.stamp}/mule/user中。
