I think this is a very good point. The quickstart/examples should at least illustrate how an ESB message can be broken down into context instance variables so they are available to the EL in jBPM (decision nodes, task assignments, etc.)  By default we can push the whole message in as a single instance variable for "free" meaning no work on by the user (you the ESB programmer).   

The Message could be pushed through a transformation action and returned as POJOs (see the transform_XML2POJO) and you can then use a custom action to load those POJOs into instance variables for jBPM.

We also need a known message header property to store the token id for correlation purposes.

Thanks Rex!
