eclipse modeling for wtp
DESCRIPTION
These slides have been presented at Eclipse Summit Europe 2010. This talk will show how Eclipse Modeling technologies could be used to design JavaEE applications. It will be illustrated by: * EMF to design a DSL for WebApp, * GMF to design screens, services, entities, enterprise architectures * Acceleo to generate to Spring, Struts, Hibernate and others * ATL to import UML/Togaf models The story of a travel agency is used as an exemple. It show how to create a simple DSL, how to create my own graphical workbench with Obeo Designer, and how to integrate this application inside a Togaf compatible architecture. It will show how WTP and EMP fit well together for developers, architects and designers. It will also prove with the same model how easy are the evolution management with the updating of a generator to target a new JavaEE framework.TRANSCRIPT

My goals for today:
Use a DSL to find the intention
Generate JavaEE
Create my own designers
Integrate the result in an Enterprise Architecture
Lets try this story:
We are a travel agency,
and we want to create an
enterprise blog

We can create our own "generator by convention"
Conventions exemples :
An Entity is identify by a technical ID associated to a Sequence
The name of the table is by default the name of the Entity

Graphical modeling
"Domain-specific modeling (DSM) is a software engineering methodology for designing and developing systems, such as computer software. It involves systematic use of a graphical domain-specific language (DSL) to represent the various facets of a system."
