<bean id="jmsConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
    <property name="brokerURL" value="tcp://localhost:61616" />
</bean>

<bean id="jms" class="org.apache.camel.component.jms.JmsComponent">
    <property name="connectionFactory" ref="jmsConnectionFactory" />
</bean>

<bean id="transactionManager" class="org.springframework.transaction.jta.JtaTransactionManager">
    <property name="userTransaction" ref="userTransaction" />
    <property name="transactionManager" ref="transactionManager" />
</bean>

from("jms:queue:inputQueue")
    .transacted()
    .process(new MyProcessor())
    .to("jms:queue:outputQueue")
    .rollback();

onException(Exception.class)
    .handled(true)
    .process(new MyExceptionHandler())
    .rollback();
