I am using mule 3.8.0 , my flow is as follow

 <amqp:connector name="AMQP_0_9_Connector" validateConnections="true" host="XXX.XX" username="XX" password="XX" doc:name="AMQP-0-9 Connector"/>
 <flow name="rabbitmq_mavenFlow">
        <servlet:inbound-endpoint path="/message" responseTimeout="10000" doc:name="Servlet"/>
        <set-payload value="test message " doc:name="Set Payload"/>

        <amqp:outbound-endpoint  queueName="orders"  queueDurable="true" responseTimeout="10000" exchange-pattern="request-response" connector-ref="AMQP_0_9_Connector" doc:name="AMQP-0-9"/>

Please help me to solve it

Thanks

@user3855589, you probably have two different versions of commons-logging: one in your war and one in tomcat. You should put the one in your war in provided scope (if you are using maven) or just exclude it from your war, and than deploy it in Tomcat. Check out a similar error.
