Mule ESB : Cannot copy message with a stream payload - esb

Question

I have a Mule Application where I send a Request to Multiple WebServices and aggregate the List of responses i get , the idea is to get the first response of the List by returning it from the CustomJavaClass where the list is handled :
return responses.get(0);
I am able to reach the WSDL if I try to reach it over a Browser , the returned WSDL looks like its supposed to look . But i I try to send a message via SoapUi i get the following exception :
Exception stack is:
1. Cannot copy message with a stream payload. Payload type is "org.apache.commons.httpclient.ContentLengthInputStream". Message payload is of type: ContentLengthInputStream (org.mule.api.MessagingException)
org.mule.routing.outbound.AbstractSequenceRouter:73 (http://www.mulesoft.org/docs/site/current3/apidocs/org/mule/api/MessagingException.html)

Answer 1

Getting the WSDL works because the GET request carries no payload. But when you try to invoke a SOAP method, the POST payload is an InputStream, which of course can't be dispatched several times.
Thus: serialize the HTTP input stream with a:
<object-to-byte-array-transformer />
right after the http:inbound-endpoint.
