[ATL] problem with programmatically transformation output model [message #42255] Mon, 28 May 2007 13:41 Go to next message

Hi all,

I'm trying to perform an ATL transformation programmatically, but the
method:

AtlLauncher.getDefault().launch(transformation, libs, models, params);



returns an ASMEMFModel with no modelElements. This is driving me crazy,
I'll be very thankful with the one who is able to help me!

Hello,

Firstly, The target models are passed as entries of the models argument.
There are not "returned" by the launch method, which returns the value
of a query (and nothing for transformation modules).


Secondly, if you still have a problem: are there any execution errors?

If not, you could try to add calls to OclAny.debug(message : String) :
OclAny in your code (e.g., in rule guards, even if they have none: use
true.debug('matching')) to see if rules are matched.

If rules are not matched, then it may mean that you have not passed a
source model conforming to your source metamodel.
This can happen if you have loaded your metamodel twice, and do not pass
as argument to launch() the metamodel that was used when loading the
model. Another issue, with EMF, is if you override the package registry
entry by loading another (or the same) metamodel with the same nsURI.


Best regards,

Frédéric Jouault

Is that correct? I have doubts about the fact that among the ModelElements
don't appear the defined elements in my metamodel WIKI.ecore (like 'Section'
or 'LinkItem').



This happens also with the UML input model.

May this be the reason the transformation doesn't work? (I checked that I
pass as argument to launch() the metamodel that was used when loading the
model)



I thank you in advance,

Hello,

It seems that you are trying to use the XML extractor, but that only
works if your target model is the XML metamodel:
http://www.eclipse.org/gmt/am3/zoos/atlanticZoo/#XML

Otherwise, you should simply save your model with the AtlEMFModelHandler
to XMI.


Best regards,

Frédéric Jouault

Hello,

The transformOneToOther method seems to transform an XML model/document
into an XML model/document. However, it seems that you do not use the
XML metamodel as target. Therefore, you should probably not use this
method, but use a more generic one that transforms XMI to XMI.

Milan can probably tell you more about this, because I do not know his
code ;-).


Best regards,

Frédéric Jouault

Hi,

well, this error is not related to my class ATLTransformations.
I far as I can see this is again related to versions of Ecore for
the UML 2 metamodel which you use in this case and when you have
created that metamodel.
