Java EE: "Your First Cup" tutorial gets the UML Parsing Analysis treatment in a super new demonstration !

[blog] Submitted by webel on Tue, 25/08/2009 - 09:25

This is the most comprehensive demonstration of application of Dr Darren's UMLTM Parsing Analysis recipe to software engineering yet, and forms the basis of a new Webel seminar. Selected sentences of Your First Cup: An Introduction to the Java EE Platform are modelled in UMLTM with traceable binding to analysis elements via source text «wrapper» Components, to form an analysis layer, which is then bound to reverse engineered "designed" elements from Sun's Java EE tutorial. UMLTM Parsing Analysis helps "make words run" ! Visit:

Java EE Containers


A UMLTM Parsing Analysis navigation diagram after the structure of Your First Cup: An Introduction to the Java EE Platform. In order to enable illustration of the different component types in the prefacing sentences, the source text sentences referring to particular container types will be treated before some of the earlier sentences.

Java EE Technologies Used in the Business Tier


These are not elaborated yet in the "first cup" tutorial, so we'll just move on.

Java EE Technologies Used in the Web Tier


Each purpose description in Table 2-1 Web-Tier Java EE Technologies becomes a source text «wrapper» Component for each technology, and acts as a navigation point to a dedicated focus diagram. Eventually each «wrapper» Component will also be linked to live examples right here on this web site

Java EE Servers


As a navigation diagram, after the structure of Your First Cup: An Introduction to the Java EE Platform. In we go to find out now how the Java EE server relates to the existing analysis using UMLTM Parsing Analysis, sentence-by-sentence ..

NeXML: a generative XML Schema with EMF Java bindings for the NeXus scientific data format

The NeXML project showcases UML, Java^TM, and XML Schema technologies employed by Webel. Find out how the Eclipse XSD library and Eclipse Modeling Framework (EMF) were used by Dr Darren to generate an XML Schema with automated Java bindings from the XML templates of the NeXus scattering science data format.
	This image shows an `NXcrystal` component instance within an `NXinstrument` instance, in the first validating editor for the NeXus format, thanks to EMF. It was generated using Java by the NeXML transformation system from a NeXus "Meta-DTD" XML template.

In 2005 I assessed The Netbeans Platform as a candidate for developing client applications.

As always when examining a new JavaTM API and related software tutorials and docs, I fired up MagicDrawTM UML and did some reverse-engineering (in this case of the Java sources) into graphical UMLTM, to get a feel for the API. And as usual, I used additional «wrapper» Components in my diagrams (rather than just relatively graphically unstructured "freestyle" class diagrams) to logically and graphically group related model elements. Some UML diagram examples are made available here.

These diagrams are much larger than I recommend, they need to be progressively "divided and conquered" into related diagrams that can be navigated in the UML project via model element hyperlinks. I usually start like this then split the diagram into related "class collaborations". Also, I do not usually recommend showing so many methods/operations of multiple classes and interfaces. These are nevertheless very good examples of the power of UML diagramming with logical «wrapper» Components, in fact they capture my "wrapper" process nicely.

These barely count as examples of UMLTM Parsing Analysis, because there is very little true ordering and binding of independent technical text or tutorial documentation to the UML model elements, however this is a good candidate for further iterations. Performing such a sweep of reverse engineering and diagramming helps make the Java development flow enjoyably.

The Sun shines on Webel thanks to UMLTM-driven JavaTM !

Please find thoughout this site many of examples of JavaTM engineering projects and educational tips on JavaTM technologies, mostly from real-world Webel projects and usually with supporting Unified Modeling Language (UML)TM diagrams. Check out the links below, as well as the Java keyword search to list every page on the site that involves Java. Now that's a large mug of very hot UML-driven Java !
