How do I retrieve the thrown Exception during processing an Exchange

You have send an Exchange to Camel but it fails during processing caused by a thrown Exception. How do I retrieve this Exception?

If you are using CamelTemplate (or CamelProducer), then its common to use the sendBody/requestBody methods that returns the exchange body response only. So if there was a thrown exception during processing Camel is not rethrowing this Exception. To remedy this you can use the plain send/request methods that accepts an Exchange object and returns an Exchange object.

From the returned Exchange you can test if its failed and get the caused exception. This is illustrated in the code sample:
