Hi:
I am having the same problem with a BPMN model created with BPMN2Modeler, but using the model as an input for an Acceleo project in this case.
When I try to create a module file in the Acceleo project, the metamodels that the model is conformant to have to be added. The graphical interface allows to choose among the registered metamodels, including:
http ://www. omg. org/spec/BPMN/20100524/DI
http ://www. omg. org/spec/BPMN/20100524/DI-XMI
http ://www. omg. org/spec/BPMN/20100524/MODEL
http ://www. omg. org/spec/BPMN/20100524/MODEL-XMI
http ://www. omg. org/spec/DD/20100524/DC
http ://www. omg. org/spec/DD/20100524/DC-XMI
http ://www. omg. org/spec/DD/20100524/DI
http ://www. omg. org/spec/DD/20100524/DI-XMI
that were registered when BPMN2Modeler was installed.
If I try to choose the metamodels not ending in -XMI, the graphical interface does not add them to the module file and doesn't yield any error message. On the other hand, if I choose the metamodels ending in -XMI, they are added to the module file.
However, when I try to run an example (both an example of mine or the example base.bmpn provided by Gonzalo López) the execution fails with the same error message that Alijia Bouzidi gets:
Exception in thread "main" org.eclipse.emf.ecore.resource.impl.ResourceSetImpl$1DiagnosticWrappedException: org.eclipse.emf.ecore.xmi.ClassNotFoundException: Class 'definitions' is not found or is abstract.

at org.eclipse.emf.ecore.xmi.impl.XMLHandler.validateCreateObjectFromFactory(XMLHandler.java:2298)
. . . many more lines
I have tried another approach, changing manually the metamodels in the module file, specifying the metamodels not ending in -XMI, but the same error happens.
I guess the underlying reason for the failure is the same than in Aljia Bouzidi's case with ATL.
I would like to clarify that I have chosen the above mentioned metamodels because they are referenced in the model file (see attached file) in the bpmn2:definitions element, in paticular the fields xmlns:xsi, xmlns:bpmn2, xmlns:bpmndi, xmlns:dc and xmlns:di, but I admit that I do not know if they are the metamodels that have to be referenced.
Thanks in advance for any help.

Dear Gonzalo:
Thank you very much for your answer. I have been able to replicate to example and define a meaningless transformation (from BPMN to Families, the Families in the ATL tutorial first example):
-- @path BPMN2MM=/org.eclipse.atl.gonzalo.lopez.sample/BPMN20.ecore
-- @path FamiliesMM=/org.eclipse.atl.gonzalo.lopez.sample/Families.ecore
module bpmn2families;
create OUT : FamiliesMM from IN : BPMN2MM;
rule Definitions2Family {
from
s: BPMN2MM!Definitions (true)
to
t: FamiliesMM!Family (
lastName <- s.Name
)
}
However, the execution of that transformation on your base.bmpn model fails in the same way as in Acceleo:
Class 'definitions' is not found or is abstract. (file:/Users/jmalvarez/workspaces/photon-mod-dsl-workspace/org.eclipse.acceleo.gonzalo.lopez.sample/models/base.bpmn, 3, 541)
Thanks for your help.
