Open Architecture Ware 5 EMF - Mini Intro Tutorial

Bookmark on del.icio.us
Posted on January, 19 at 6:25 am

Currently, i’m in the OSF@ALMA project and i will be here until March/2010, so my task here is migrate and implement a Alma Common Software Code Generator using Open Architecture Ware 5 (oWA5), so there’s a few things and hacks that you have to understand:

For old users of oWA, i mean, oWA 4.x.x, now oWA is under the eclipse umbrella and is part of Eclipse Modeling Framework EMF, from the version 5, oWA means MWE (EMFT) + Xpand (M2T ) +Xtext (TMF).

  • First of all, download a ready-to-use Eclipse here.
  • Install the last version of Antlr in Eclipse for Xtext and run the Workflow, Eclipse url Antlr install http://download.itemis.com/updates/ (this is in eclipse, Install new software…etc..etc..).
  • Some issues about project wizard creation in Xpand in oAW 5, missing classes and bad Workflow file definition, solved in bugzilla 283942.
  • Update the MANIFEST file, adding the oWA 5 libs defined under EMF and enable the project specific settings in Xtend/Xpand (project properties) UML2 Profiles and EMF Metamodels, UML2 have to be the first in the list.
With the things above, create a wizard project, in this case i use UML models exported from MagicDraw, this UML models are under the XMI 2.0 standard and they will be your metamodels, or just use the example wizard.
If your are new at this, run the workflow file created, right lick -> run-as ->MWE Workflow, the project have to generate some Java code from the UML models.
I will recored a screencast and how to modify the workflow for custom uses.

When you are working in certain project that use a certain framework and for create a module (i.e.) you have to create several class files, and each class file has serveral atrributes and methods, it’s very annoying, so, why not create a liitle program to generate the code under our methods and attributes ?, ok, now you will say… how i do that ?, simple, with Java in this case you can do it, theres a library called JTM Java Emitter Templates, it’s a tool from Eclipse Modeling Framework EMF, and create our codes under templates files, so, it’s very easy and very helpful to generate custom code, even further you can create a Java App that use JET with a databse engine, to get our code under maintenance, how to this ? check this link above :
