This was definitely a PEBKAC problem. I was missing the decoder= part in the netty4 configuration. So the response never got decoded to something meaningful.
Sorry for bothering you all and being completely blind. Claus & Willem I owe you at least one beer. Cheers, Thomas.

(eg the pipes and other control chars it may contain). I can see the same on adding some logging to the camel-hl7 unit tests. So that may be why your "log ${body}" do not print anything.

When using to uri=„log:…“ (Log component) it shows the body-type as unpooledunsafedirectbytebuf. This statement works ok. And yes, it should contain the ack response. When using <log message=„*** ${body} ***“/> (or anything else that needs a string, like convertbodytostring, etc) I get exceptions. Even when the first statement after netty4 is to-file it does not work. So there should be no one consuming it before. The codecs are default. <bean id="hl7nettydecoder" class="org.apache.camel.component.hl7.HL7MLLPNettyDecoderFactory"> </bean> <bean id="hl7nettyencoder" class="org.apache.camel.component.hl7.HL7MLLPNettyEncoderFactory"> </bean> I will continue to strip my complex project down.

My more elaborate version breaks. But basically it is: queue->transacted->convertbodytostring->setSomeHeaders->log->netty4->log The netty4 listening to my message gets the message and returns an ack. When I try to get it as a string—>it breaks. I do have a DefaultErrorhandler configured. But it should not kick in if everything works ok. Just to be clear. Its that last part netty4->log Where you attempt to log the netty4 response (eg the ack response) ? Do you use any special codec or encoders with netty4 or something? And what version of Camel do you use? When I change the netty4 endpoint to mina2 -> it works. So I assume the problem lies with the netty4 component. Maybe the codecs? Why do I not use mina2? Because ultimately I want TLS which is broken with mina2 in my version of Camel. It seems like some problem with redelivery as Claus suggested, however I am still puzzled… Cheers, Thomas.

Unfortunately it is of type UnpooledUnsafeDirectByteBuf and type conversion to string fails: ....On delivery attempt: 2 caught: org.apache.camel.TypeConversionException: Error during type conversion from type: java.lang.String to the required type: java.lang.String with value UnpooledUnsafeDirectByteBuf(freed) due io.netty.util.IllegalReferenceCountException: refCnt: 0 Sounds like you are doing redelivery and the byte buf is not reset on redelivery or something so the data stream becomes empty and not convertable to a string type. A bit like when you are not using stream caching http://camel.apache.org/why-is-my-message-body-empty.html Any ideas how to work with the ACK (besides logging which works)?
