Java code Generation from UML diagrams [message #474242] Tue, 22 April 2008 01:39 Go to next message

Hello.
I'm new to Eclipse and UML modeling. My professor has recommended that we
use Eclipse to develop UML models which will then be used to generate
executable Java code. I've successfully created the models, but am having
problems finding tutorials which explain, in detail, how I would transform
the models into Java code. Could someone suggest a tutorial I could use?

Thank you in advance for the help.

Hey Belinda,

did you already find a tool that helps you with the generation? If not, you have
several options. I'd suggest you check out the m2t project:

http://www.eclipse.org/modeling/m2t/

It provides several subprojects that help you to generate text from emf based
models (which UML2 is). Once you decide for a language, you can look if there's
any tutorial for it. Usually though the tutorials are for simpler input models ,
i've only the one from openarchitectureware.org (xText) manual:

http://www.eclipse.org/gmt/oaw/doc/4.2/openArchitectureWare- 42-reference.pdf

I'll check this out. I was able to find the "Generating an EMF Model"
tutorial, but it didn't give me exactly what I needed; I'll definately try
this.

Thanks again!

Hey Belinda,

note that EMF/Ecore models are not the same as UML Models. Its a bit
confusing at first, but you´ll find out.

I´d suggest you to read the EMF Overview, even if you´re going to work
with UML Models later. The UML2 wiki has some articles that show you
what´s going on behind the curtain when you draw your diagrams.

Hello Belinda,
Felix is correct, UML is converted to EMF, Java code is generated from EMF
file.

Diagram is described by two files - semantic model file(*.uml) and notational
model file (*.umlclass_diagram). Notation describes how UML elements a shown
and placed on the diagram; semantic model is UMl model itself, it's what
we will use in our subsequent code generation.

At the moment algorithm to generate Java code from UML diagram is the following:

1. Convert UML to EMF
Select *.uml file and launch New/Eclipse Modeling Framework/EMF model wizard.

Leave 'UML model' as a model importer on the second page.
Click 'Load' button, then click 'Process all' button on the third page.
Press 'Finish' on the forth page.

2. Generate Java from EMF
Open just-created *.genmodel file, select package and call 'Generate Model'
action.
Generated code is what you want. More details about code-generation are in
paper Felix gave ( http://help.eclipse.org/help33/index.jsp?topic=/org.eclipse. emf.doc//references/overview/EMF.html)


Best wishes,
Tatiana.

UML modeling is really old. The best way to me to model my application is at the database level. So I build out my database model and then use Jigy Generator (created by the getjigy team) to create my application. I just fill out a simple form and Jigy Generator reverse engineers my database into a fully configured Spring MVC Java web application. All of my DAO's, domain objects and validators are created for me... these really represent my data model. Also it has some built features that just work out of the box like login, authentication, file upload, etc. If you're like me and don't like starting your java projects from scratch, you should give Jigy Generator a try.

Hi Andrew,

I tried my hand at Jigy Generator, without much success. I am trying hard to get it to work.

I am facing challenge in generating eclipse project using Jigy Generator 1.0.4. After providing the mandatory information on the create project page, the download page never appears. The orbiting hour glass overlay never goes away. (Sidenote: I checked using firebug, the HTTP request received a response "Success".)

Can you share with me how have you setup your Jigy Generator and the database?
