Subject Re: Camel Aggregator Exception
Date Thu, 27 Jun 2013 12:56:17 GMT
You have a class not found exception

java.lang.ClassNotFoundException:
org.apache.camel.processor.BodyInAggregatingStrategy

The idea is that you create your own custom aggregation strategy where
you "merge" the data together.

Read about the aggregate EIP pattern to learn more
