Java

The Sun shines on Webel thanks to UML™-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™) 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 !

Gallery: UML Parsing Analysis models of the J3D tutorial

This content or the technology discussed here is HISTORICAL or ARCHIVAL

An older - and still useful - demonstration from 2003, illustrating binding of documentation text to UML elements, and an attempt to mimic freestyle Java3D tutorial figures with custom stereotypes images for UML element symbols.

As always when I try out some new software, I performed a UML™ Parsing Analysis of the J3D tutorial, binding the text to the reverse-engineered software (design) components and analysis components in MagicDraw™ UML. However, since I use Java3D frequently, I went to particular lengths in this case, which turned out to be effort well-invested, since it has made working with the API much easier.

It is much to the credit of the Java3D documentation team that the interpretation as UML models falls out so easily and consistently; if only all software vendors would produce documentation as clear and enjoyable as this tutorial ! Of course my UML™ Parsing Analysis diagrams do not replace the tutorial in any way; you SHOULD study the original Java3D tutorial, examples, and Java3D API in detail first.

To students of Java, Java3D, and Unified Modeling Language™ (UML™): it is not so much that I expect my own UML models of Java3D to be of direct benefit to you, rather my reason for posting this material is to show you how I go about cutting my teeth on Java software APIs and documentation.

I provide here only some selected UML diagrams, mostly from "Chapter 1: Getting Started".

Includes screenshots and reverse-engineered UML diagrams from some of the Java Swing and Java versions of DranceWare.

Gallery: JUNG: UML Parsing Analysis of the documentation and reverse-engineered Java JUNG API (from 2003)

This content or the technology discussed here is HISTORICAL or ARCHIVAL

Some preliminary UML™ Parsing Analysis models (from 2003) of the JUNG documentation and the API. It took only a couple of days to parse the docs into UML™ models and then get an example application running with real data.

TIP for Java and UML students: first read the docs of a new API a bit; then "parse" the docs a bit into UML™, binding them to reverse-engineering of the actual software (the implemented design, the "grounding force"); then develop your application under model-driven development. It is not enough to see how I did it, you have to make the experience of it, you have to wrap your neurons around your own UML™ modelling, you have to do it with your own hands and your own brain. Give it a go !

UML zone

[book] Submitted by webel on Mon, 17/11/2008 - 21:08

This Webel zone is dedicated to the Unified Modeling Language™ (UML™), to UML™ education, and to applications of UML™ beyond software engineering to science, engineering, art, and much more.

Dr Darren, long time UML™ user and educator, says:

"The more I use the UML the more I believe in it's potential and importance as a lingua franca of information technology. I am a true UML advocate. It is, quite simply, one of the most important technologies in the history of humankind."

This is also the home of Dr Darren's powerful UML™ Parsing Analysis recipe for translating text documents into UML™ and SysML analysis models. And you'll find lots of examples of the applications of Systems Modeling Language (SysML) to science and engineering problems.

XML zone

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

[book] Submitted by webel on Sun, 16/11/2008 - 15:52

This content area is UNDER CONSTRUCTION or MIGRATION

The NeXML project showcases some Unified Modeling Language™ (UML™), Java™, and XML Schema technologies employed by Webel. It is under migration from a standalone JSP-driven zone to a new Drupal™-driven Content Management System (CMS) zone.

The old NeXML site - although now FROZEN - is fully functional and very informative, with good examples of EMF and dynamic XSD schema engineering

A comprehensive report with abstract and PDF attachment is available here:

NeXML: automating generation of an XML schema and EMF Java bindings from the XML templates

And there is a screencast movie of a presentation from the Meeting of the NeXus International Advisory Committee (NIAC), 2008:

Gallery: UML reverse-engineering of (part of) the Netbeans Platform tutorial (from 2005)

This content or the technology discussed here is HISTORICAL or ARCHIVAL

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

As always when examining a new Java™ API and related software tutorials and docs, I fired up MagicDraw™ UML and did some reverse-engineering (in this case of the Java sources) into graphical UML™, 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.
