Java EE zone

Keywords:

A Webel zone dedicated to Java EE technology.

Webel specialises in model-based Enterprise Java web application development (including Java support for XML technologies and web services) with graphical Unified Modeling Language™ (UML™) support.

Webel employs the Java Persistence API (JPA) as the core database technology in combination with JPA-compliant object-relational database mapping technologies (EclipseLink and Hibernate) for relational database management systems (MySQL, Oracle DB), as well as in combination with the JPA-compliant pure-object database ObjectDB.

The powerful core JavaServer Faces (JSF) web user interface system and the PrimeFaces 3rd-party JSF GUI toolkit are used to create rich interactive web worksheets for Enterprise Java web applications from data and objects served from database via JPA and managed via mediating Enterprise Java Beans (EJBs) employing Expert System strategies:

For demonstrations and examples, please visit the tutorial presentations and demonstration videos of the GreenDesk web application for modelling and environmental compliance tracking of office buildings, developed by Webel for GreenSoft.

The Oracle and the Sun shine 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

Keywords:

The 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".

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

Keywords:

The 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 !

For information on Webel IT training courses and analysis services in advanced graphical UML™ and SysML™ please visit:

- Advanced UML and SysML training seminars and workshops

- Service: IT Training: Unified Modeling Language (UML), Systems Modeling Language (SysML), and UML-driven Java

This Webel IT Australia zone is dedicated to the graphical Unified Modeling Language™ (UML™), to UML™ education, and to applications of UML™ beyond model-driven 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.

Dr Darren is recognised as a leader in model-based engineering and graphical software and systems engineering technologies.

The NeXML project, based on work performed on the NeXus neutron science data format for the Bragg Institute, Australian Nuclear Science and Technology Organisation (ANSTO) between 2006-2008, showcases some Unified Modeling Language™ (UML™), Java™, and XML Schema technologies employed by Webel:

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

Keywords:

The 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.
