Hi,
I get the following backtrace when setting the ATL model handler:
AtlEMFModelHandler:: getting resource
AtlEMFModelHandler:: got resource: null
SEVERE: null
java.lang.NullPointerException
at org.eclipse.m2m.atl.drivers.emf4atl.ASMEMFModel.loadASMEMFMo del(ASMEMFModel.java:334)
at org.eclipse.m2m.atl.engine.AtlEMFModelHandler.<init>(AtlEMFModelHandler.java:216)
at org.eclipse.m2m.atl.engine.AtlModelHandler.getDefault(AtlMod elHandler.java:61)
at meta.custom.Transform.doATLTransformation(Transform.java:97)
> Transform.java:97: this.amh = AtlModelHandler.getDefault(AtlModelHandler.AMH_EMF);
with amh declared as "private AtlModelHandler amh"
This is with todays ATL. Should I file a bug report?
Regards,
Rene

The error seems to come from the model you're trying to load, after
setting the modelhandler (but I may be wrong).
Could you please attach your (latest) Transform.java file, and if
possible, the sample you're using (models, transformation).
Otherwise, some examples of programmatic launch can be found here :
- ATL non-regression tests :
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.m2m/org .eclipse.m2m.atl/tests/org.eclipse.m2m.atl.tests/?root=Model ing_Project
- ATL examples :
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.m2m/org .eclipse.m2m.atl/examples/org.eclipse.m2m.atl.examples/src/o rg/eclipse/m2m/atl/examples/?root=Modeling_Project

William

I didn't reproduce it exactly but I saw that a dependency is indirectly
required by the EMF model handler, org.eclipse.emf.ecore.xmi .
If it doesn't work, could you please report a new bug ?
Thank in advance
William

According to the "About Plug-ins" window I have org.eclipse.emf.ecore.xmi
v2.3.2 200802051830 installed. Both 2.3.1-200709252135.jar and
2.3.2-200802051830.jar are in the plugins directory.

Actually this is not needed, because it was triggered by some environmental
issue which causes Eclipse unable to find ATL-0.2.ecore (I think there are
archives on this). I'm now testing ATL 2.0.0v20080505 with Eclipse 3.4M7/EMF 2.4M7.

Rene
