Hello all,
I am trying to build a wrapper to call some ATL code from Java. I have a
problem which I think is related to the versions of libraries.
I have already read the "How do I launch transformations
programmatically?" article from eclipse wiki. I started from Milan
Milanovic's example. I need to transform UML2.0 models, so I am using the
metamodel written in ecore,
from http://dev.eclipse.org/viewcvs/index.cgi/
org.eclipse.mdt/org.eclipse.uml2/plugins/org.eclipse.uml2.um l/
model/UML.ecore?root=Modeling_Project&view=log .
The list of libraries I use is:
antlr.jar
ATL-importer.jar
ebnfextractor.jar
ebnfinjector.jar
jmi.jar
jmiutils.jar
KM3-importer.jar
km3.jar
mdr4atl.jar
mdrapi.jar
mof.jar
nbmdr.jar
openide-util.jar
org.eclipse.runtime.compatibility_3.1.100.v20060603.jar
TCS-importer.jar
org.atl.eclipse.engine.jar
vm.jar
org.eclipse.emf.common_2.1.0.jar
org.eclipse.emf.ecore.xmi_2.1.0.jar
emf4atl.jar
org.eclipse.core.resources_3.1.2.jar
org.eclipse.core.runtime_3.1.2.jar
org.eclipse.m2m.atl.drivers.uml24atl_2.0.1.v200809170426.jar
org.eclipse.emf.ecore_2.1.0.jar
I have tried to run this first in Eclipse Modeling Tools (Eclipse 3.4) and
then in Eclipse 3.1.2, but with the same problems:
First, when I try to load the UML metamodel, if I use either emfamh or
umlamh:
private AtlModelHandler emfamh = null;
private AtlUML2ModelHandler umlamh = null;
emfamh = AtlModelHandler.getDefault(AtlModelHandler.AMH_EMF);
oneMM_EMF = emfamh.loadModel("OneMM", emfamh.getMof(),
onemmurl.openStream());
umlamh = new AtlUML2ModelHandler();
oneMM_EMF = umlamh.loadModel("OneMM", umlamh.getMof(),
onemmurl.openStream());
I get the error:

I checked with the debugger and both emfamh and umlamh get intialized. I
think the problem is in the difference between
the UML2.0 metamodel (the ecore file), and the libraries which implement
it (or ecore) in eclipse. I noticed that
org.eclipse.emf.ecore_2.1.0.jar, in its org.eclipse.emf.ecore package does
not have an EGenericType.class, while
org.eclipse.emf.ecore_2.4.1.v200808251517.jar has it. So I tried to change
the org.eclipse.emf.ecore to the 2.4.1 version,
and a whole flow of errors started:

... 21 more
at the code line:
emfamh = AtlModelHandler.getDefault(AtlModelHandler.AMH_EMF);
Now I am thinking if I should change other libraries as well, or if the
problem is in another place.
Any suggestion will be highly welcomed.
Thank you in advance,
Vanea
