Hi Allen, That seems to me to be a matter of streaming, look here: http://camel.apache.org/stream.html

The rest call expects a JSON string and returns one in its response. I can do an unmarshal like in the examples provided on the Camel Jackson page and it works fine, but I'm having trouble with the marshal element. <dataFormats> <json id="jsonSend" library="Jackson" unmarshalTypeName="my.app.json.SendMessage" /> <json id="jsonReceive" library="Jackson" unmarshalTypeName="my.app.json.ReturnMessage" /> </dataFormats> ... <route> ... <marshal ref="jsonSend"/> <log message="${body}" loggingLevel="INFO"/> <!- prints the JSON string --> <to uri="cxfrs://bean:rsClient" id="clientEndpoint"/> <unmarshal ref="jsonReceive"/> <log message="${body}" loggingLevel="INFO"/> <!- prints a reference to a ReturnMessage object --> ... </route> When I attempt to marshal, I have a SendMessage object as my (in) message body. After the marshalling occurs, the logging message prints out ${body} as an equivalent JSON string. At this point, however, the route hangs and the rest call is never reached. It turns out to fix this, I have to put <convertBodyTo type="java.lang.String"/> after the marshal element. Is this expected behavior? I didn't see a need for this in the examples. It occurred to me that the logging element could be calling a toString method under the hood, so what I'm seeing in the log is not really the object that is present. However it seems odd to me that after a call to marshal that the ${body} is not a String since the whole point is to serialize the POJO. The unmarshal step definitely converts the return JSON string to a POJO, and the log statement following it indicates that ${body} is a ReturnMessage object. ---------------------------------------------------------------- innogy SE Vorsitzender des Aufsichtsrates: Dr. Werner Brandt Vorstand: Peter Terium (Vorsitzender), Dr. Hans Buenting, Dr. Bernhard Guenther, Martin Herrmann, Hildegard Mueller, Uwe Tigges Sitz der Gesellschaft: Essen, Eingetragen beim Amtsgericht Essen, Handelsregister-Nr.
