Aha ! And so it is we begin to solve the long-standing riddle of the relationship between the Java EE server and the analysis tiers gleans earlier from sentences of Your First Cup: An Introduction to the Java EE Platform. Just as well the UML™ Parsing Analysis recipe was employed patiently, and unwarranted assumptions were avoided.

I've preempted the notion of a "contained" JavaEE component, being careful to not assume that every Java EE component is necessarily contained.

Also, we don't know yet exactly which hosted JavaEE components correspond to which tiers, or how. Maybe that's revealed soon ..
