For example it will invoke the commit method with polledMessages=0 in case there was 0 files polled. http://camel.apache.org/polling-consumer.html from("file:data/csv?fileName=input-customer3.csv&pollStrategy=#myPollStrategy").to("file:data/csvoutput") And then you need to register your custom PollingConsumerPollStrategy in the Registry with the bean id "myPollStrategy". If you use a Spring XML file then its simply just <bean id="myPollStrategy" class="com.mycompany...."/> > > > Thanks in advance > -- Claus Ibsen ----------------- FuseSource Email: cib...@fusesource.com Web: http://fusesource.com Twitter: davsclaus, fusenews Blog: http://davsclaus.blogspot.com/ Author of Camel in Action: http://www.manning.com/ibsen/
