Additionally, is there a place where I can read predeclared variables? <variables> | <variable esb-name="eVar1" jbpm-name="counter" value="45" /> | <variable esb-name="BODY_CONTENT" jbpm-name="theBody" /> | </variables> For example, the ESB variable "BODY_CONTENT" seems to already exist. What is this? I'm assuming this line retrieves the complete body of the message? (though if so, why set the objects attached to the body in seperate variables) As I understand it, "name" results in a message.getBody().get( "name" ). Is this so? I'll be happy to be forwarded to some literature where I can find answers my questions, I can't seem to find much documentation on this mapping ~~.
