Headers are name-value pairs; the name is a unique, case-insensitive string, and the value is of type java.lang.Object .
Attachments are typically used for the web service and email components.
The body is of type java.lang.Object, When the sender and receiver use different body formats, Camel provides a number of mechanisms to transform the data into an acceptable format, and in many cases the conversion happens automatically with type converters, behind the scenes.
