Problem with printing In.message.body
I create a new class that simply prints out the contents of the message. I am
finding the println command is changing the contents of the body.
As this code demonstrates,
<1> STEP1 prints out the body as string.
<2> STEP2 contains no output, the body is gone.
Why is the body empty in STEP2?
Is there a better way to printout the body?
public class ConsumerScreen implements Consumer {
public void process(Exchange exchange) throws Exception {
// STEP1 - GOOD - HAS CONTENT
System.out.println(lineSep + exchange.getIn().getBody(String.class));
// STEP2 - BAD - HAS NO CONTENT
System.out.println(lineSep + exchange.getIn().getBody(String.class));
}
}
Thanks,
Michael

Hi
Your body is most likely stream based that do not support re-reading the stream.
So either enable stream-caching, or convert the message body to
something that is not a stream.
