Question

In mule flow I need to compare the last two params from an input string message

2012-04-30,2012-05-30,1,5

And if param1(1) <= param2(5), I need perform jms:outbound-endpoint.

Is there a standard choice element to do it? Could you please provide example.

Answer 1

While using mule 3.2.x your best option is to use the groovy evaluator and use a choice router that look like the following

 <when expression="#[groovy:payload.split(',')[2] &lt;= payload.split(',')[3] ]">
      <processor-chain>
          <jms:outbound-endpoint queue="out" doc:name="JMS"/>
      </processor-chain>
 </when>

Otherwise if you are willing to upgrade to Mule 3.3.0 you can take advantage of the new Mule Expression Language that allows to do the same without the need of the groovy operator
