All you need to do is reorder your method calls. 1) Create Context 2) Add Route 3) Create Template 4) Start Context (you might have to pause after this to let the context spin up) 5) Send Message (i.e. pt.sendBody) Here is an example [1]. It's not an exact match but it shows the concept where steps 1-4 are done in the constructor, step 5 is done on the invocation.
