WS Rest - Post parameter

Error:

I've built a REST WS Consumer, and am attempting to pass a large amount of XML (about 32K) through a post parameter.

I'm receiving this error:

javax.ws.rs.ProcessingException: java.io.IOException: Error writing to server

Cause:

 The WS Consumer is attempting to post the entire parameter through the header of the message

Solution:

Enable the Post Query String option of the WS REST Consumer activity to allow for query parameters to be sent within the message body
