Creating Rest Web Services in mule is very easy and explained in previous post Now If you want to preserve the rest response in your flow , or apply some checks on it or send it to other flows , you will write following java code to do this :
//If you want to transform or send the request from your jersey component to next resource/flow then you need to use
ContainerResponse cr = (ContainerResponse) eventContext.getMessage().getInvocationProperty("jersey_response");
String messageString = (String) cr.getResponse().getEntity();
message.setPayload(messageString);
//remove this property
eventContext.getMessage().removeProperty("jersey_response",PropertyScope.INVOCATION);
This code will convert org.mule.module.jersey.MuleResponseWriter$1 type to String, which you can forward to your next resource.
If you don't do that , you might get exception like this :
Message : java.io.NotSerializableException: com.sun.jersey.spi.container.ContainerResponse (org.apache.commons.lang.SerializationException). Message payload is of type: String
Code : MULE_ERROR--2
