logging/incrementing simple counter

[Baltej Singh]

Tring to create a simple counter to track some stats, not using the metrics 
related components.
Just need to log execCount and do execCount++ everytime route is entered.
What is the syntax for logging results of bean method?
i.e. logging result of:   <bean ref="execCount" method="longValue"/>

Thanks,
Baltej

               <bean class="java.lang.Long" id="execCount">
                              <constructor-arg index="0" value="1" />
               </bean>

               <camelContext>
                   <route id=" testIn">

        <from id="fileIn" uri="file:c:\test\in" />
        <log id="logPreCheck" message="Route enter:   ${execCount.longValue}" />
        <log id="logPreCheck" message=" Route enter:   {{execCount.longValue}}" 
/>
