[ATL] Launch programmatically + 2.0 bundle [message #66548]

First of all, sorry if this has been asked already. I checked everywhere and
I can find information about launching ATL transformations programmatically
(from Java code, outside Eclipse) with the old bundle, but for developing
and compiling my transformation I used the 2.0rc2 bundle.

I need to know the libraries to import in the classpath. The JARs listed at
http://wiki.eclipse.org/ATL_Howtos#Libraries_and_Prequesites refer to the
old bundle and I can't even find the first (ATL-Importer.jar) in the new
bundle. Is there a newer list of libraries?

Thank you.

Hello,

The wiki page http://wiki.eclipse.org/ATL_Howtos#Libraries_and_Prequesites
was out of date, so I corrected it. It is correct now :-), and you can
consult it again.
Thanks for reporting the problem !

Best regards,
William

I'm still trying to run a ATL transformation programmatically.

I found the following files to be also needed:
- org.eclipse.equinox.common_3.3.0.v20070426.jar (for CoreException)
- org.eclipse.core.jobs_3.3.0.v20070423.jar (for ISchedulingRule)

Now I'm facing another problem that I think it's more than just a missing
JAR.
As a first step in my code I'm initializing the EMF model handler with this
code, insipired by KM3Projector's initEMF method:

handler = AtlModelHandler.getDefault(AtlModelHandler.AMH_EMF);

and getting the following error about not being able to *initialize* (not
just find) a class.

Exception in thread "main" java.lang.NoClassDefFoundError: Could not
initialize class org.eclipse.core.runtime.Platform
at
org.eclipse.m2m.atl.engine.AtlEMFModelHandler.<init>(AtlEMFModelHandler.java:162)
at
org.eclipse.m2m.atl.engine.AtlModelHandler.getDefault(AtlMod elHandler.java:55)
at AtlTransformer.initializeHandler(AtlTransformer.java:183)
at AtlTransformer.<init>(AtlTransformer.java:37)
at AtlTest.main(AtlTest.java:14)

org.eclipse.core.runtime.Platform is in
org.eclipse.core.runtime_3.3.100.v20070530, that I already included in the
project references. I still didn't try with MDR.
How to fix the problem?

Thnaks.

Thanks to your helpe I was able to run ATL outside Eclipse!

No more exception is thrown, however I'm facing a problem where my output
model (ecore) contains only an instance of the source model element and
nothing more. The same transformation with the same input models works when
launched through eclipse. What could be causing this? Maybe I need to
specify parameters/options in the launch method?

Thanks again.

Never mind. I was using MOF as model for the input model.

It works, but behaves strange. [message #66781 is a reply to message #66696]

Ok, I was able to make a transformation work stand-alone. However, while
there is no error message, the resulting model does contain errors :(

Everything is the same: source models, transformation, etc, but the
generated model is slightly different. It's like some of the helpers are not
working. Maybe that's because I used unstable code from CVS to compile some
of the libraries? Or maybe I need to supply AtlLauncher params/options?

Thank you.
