UML Parsing Analysis

The Your First Cup: An Introduction to the Java EE Platform source text has not yet said whether greeting.xhtml "is" a Facelet, or just 'uses the the JavaServer Faces Facelets tag libraries'.

Also, it has not yet been explained what relationship (if any) the 'JavaServer Faces Facelets tag libraries' have with Expression Language (EL) tags already encountered during this UMLTM Parsing Analysis demo.

Until further info becomes available in the source text these matters are simply noted.

The source text from Your First Cup: An Introduction to the Java EE Platform is a bit confusing in a few respects here, as pedantically annotated in the spirit of UMLTM Parsing Analysis.

Firstly, we are told that 'The firstcup web application .. accesses DukesAgeResource to display Duke's age'. Does this mean that the DukesAgeResource can display Duke's age ? Or rather, that Duke's age is retrieved for display by the firstcup application ?

Also, 'The firstcup web application .. accesses DukesBirthdayBean to calculate who is older'. Does this mean there is an operation that returns a person (the Duke or the User), whoever is older ? Or is there a boolean ?

This source text snippets lends itself well to an analysis Activity Diagram, shown next ..

UMLTM Parsing Analysis «wrapper» Components are created as a bridge to whatever UML elements may result from reverse engineering the executable ("designed") Your First Cup: An Introduction to the Java EE Platform example application.

Until now in this UMLTM Parsing Analysis demo only class diagrams and composite structure diagrams have been used; these will now be complemented with activity diagrams and related Activity elements, to encapsulate the steps for creating the example application from Your First Cup: An Introduction to the Java EE Platform (which will eventually run here directly from this demo trail).
