Hello,
I would like to generate a model transformation in a Java code.I would like to know all the steps necessary to do it.
Thank you.

Thanks but I try with this code:
import java.net.URL;
import java.util.Collections;
import java.util.HashMap;
import java.util.Map;
import org.eclipse.m2m.atl.drivers.emf4atl.AtlEMFModelHandler;
import org.eclipse.m2m.atl.engine.vm.Atllauncher;
import org.eclipse.m2m.atl.engine.vm.AtlModelHandler;
import org.eclipse.m2m.atl.engine.vm.ModelLoader;
import org.eclipse.m2m.atl.engine.vm.nativelib.ASMModel;
public class Families2PersonsProgrammaticlaunch {
public static void main(String[] args) {
try {
//AtlModelHandler and ModelLoader init
AtlModelHandler.registerDefaultHandler("EMF", new AtlEMFModelHandler());
AtlModelHandler amh = AtlModelHandler.getDefault("EMF");
ModelLoader ml = amh.createModelLoader();
//stores metamodels and models
Map models = new HashMap();
//used to locate metamodels,models and trasformation file
URL url;
//URL where Families.ecore (input metamodel) is located
url = new URL("chemin d'emplacement du premier métamodèle");
//load Families metamodel (the name is the same in the ATL file [ex.: ATL CODE-> create OUT : Persons from IN : *Families*;])
ASMModel metamodel_families = ml.loadModel("Families", ml.getMOF(), url.openStream());
//store
models.put("Families", metamodel_families);
//URL where Persons.ecore (output metamodel) is located
url = new URL("chemin d'emplacement du deuxième métamodèle");
//load Persons metamodel (the name is the same in the ATL file [ex.: ATL CODE-> create OUT : *Persons* from IN : Families;])
ASMModel metamodel_persons = ml.loadModel("Persons", ml.getMOF(), url.openStream());
//store
models.put("Persons", metamodel_persons);
//URL where sample-Families.xmi (input model) is located
url = new URL("chemin d'emplacement du modèle de Families sample-Families.xmi");
//load Families model (the name is the same in the ATL file [ex.: ATL CODE-> create OUT : Persons from *IN* : Families;])
ASMModel model_families = ml.loadModel("IN", metamodel_families, url.openStream());
//store
models.put("IN", model_families);
//URL where sample-Persons.xmi (output model) is located
url = new URL("chemin d'emplacement du modèle sample-Persons.xmi( que doit le programme retourner)");
//create a new output model (the name is the same in the ATL file [ex.: ATL CODE-> create *OUT* : Persons from IN : Families;])
ASMModel outputModel = ml.newModel("OUT", "chemin d'emplacement du modèle sample-Persons.xmi (que doit le programme retourner)", metamodel_persons);
//store
models.put("OUT", outputModel);
//URL where Families2Persons.asm (transformation .asm) is located
url = new URL("chemin d'emplacement du fichier Families2Persons.asm");
//get an Atllauncher
Atllauncher mylauncher = Atllauncher.getDefault();
//execute the transformation (in this case we pass just the map "models")
mylauncher.launch(url, Collections.EMPTY_MAP, models, Collections.EMPTY_MAP, Collections.EMPTY_LIST, Collections.EMPTY_MAP);
//save the outputModel in "file://C:/Documents and Settings/Administrator/workspace2/Families2Persons/sample-Persons.xmi"
outputModel.getModelLoader().save(outputModel, "chemin d'emplacement du modèle sample-Persons.xmi (que doit le programme retourner)");
//once executed this file make a refresh on the destination folder
}
catch (Exception e) {
e.printStackTrace();
}
}
}
but I don't know is it a class in a java project or in other type of project and if it is a class in a java project unfortunately it doesn't work when I run it as a java application.

Any Java project ....
If you try to follow the example in the link I copied, you could start using the generated java code for the plugin in your java project, copying the corresponding references.

Hi,
Ok Federico I saw the link and what I need to do is the part of "ATL Plugins".I create a new ATL Plugin based on an ATL project Families2Persons.I had the same hiérarchie as the figure http://wiki.eclipse.org/Image:ATL_plugin_wizard_result.png.The java class generated by the plugin is like this:

Now I would like to Know what are the modifications which I should do to run this plugin and how I can run it.
Thank you for your interest.
