In the route below it will read the file content and tokenize by line breaks so each line can be sorted.

Example 1. 

<route>
  <from uri="file://inbox"/>
  <sort>
    <simple>body</simple>
  </sort>
  <beanRef ref="myServiceBean" method="processLine"/>
</route>

And to use our own comparator we can refer to it as a Spring bean:

Example 2. 

<route>
  <from uri="file://inbox"/>
  <sort comparatorRef="myReverseComparator">
    <simple>body</simple>
  </sort>
  <beanRef ref="MyServiceBean" method="processLine"/>
</route>

<bean id="myReverseComparator" class="com.mycompany.MyReverseComparator"/>

Besides <simple>, you can supply an expression using any language you like, so long as it returns a list.
