在Apache Camel中使用事务跨直接路由共享JMS deadLetterChannel

Question

我有一个Camel路由，它从jboss JMS队列读取消息发送到两个直接路由，其中一个直接路由成功地处理了消息并发送到另一个JMS队列，另一个直接路由处理消息失败。

我的期望是，原始交换移动到死信通道，第一个直接路由不应该提交，使用回滚将消息发送到JMS队列。

我尝试过许多可能性，但没有一个成功。下面我提供了骆驼路线。好心帮帮我。

<-- error -->

<bean id="jmsConfigTx" class="org.apache.camel.component.jms.JmsConfiguration">
    <property name="connectionFactory" ref="jmsConnectionFactory"/>
    <property name="transactionManager" ref="jmsTransactionManager"/>
    <property name="transacted" value="true"/>
</bean>

in the above code snippet  already Transactionfactory refers to the jmsConnectionFactory internally , is there any need to write one more property to refer jmsConnectionFactory .
