Hi guys,

who knows how to add a library to an EMFTVM launch config?
I have an ATL module which requires an ATL library (presenterLib.atl); they work together no problem with @atlcompiler atl2006 and a matching launch config, but I have not found a way to load the library in an EMFTVM specific launch config.

Error message:
org.eclipse.m2m.atl.emftvm.util.VMException: Error during module loading: Error during module loading: Module presenterLib not found


Thank you for suggestions.

Your libraries have to be on the "module path": http://wiki.eclipse.org/ATL/EMFTVM#Module_import

Note that the library/module name must also be a qualified name w.r.t. the module path: if the module path is "/home/someone", and your module sits in "/home/someone/package/Module.atl", then your module name should be "package::Module". See for example http://git.eclipse.org/c/mmt/org.eclipse.atl.git/tree/tests/org.eclipse.m2m.atl.emftvm.tests/test-data/Regression/Bug419433.atl


Cheers,
Dennis

Dennis, thanks for the hint. I'm not yet sure how to transfer that exactly to my problem.

The importing module is in
/com.customer.dat.modeltransformation.startek/src/com/customer/dat/modeltransformation/startek/atl/files/transformate2startek.atl

and the library to be loaded is in
/com.customer.dat.modeltransformation.startek.atl.lib/src/com/customer/dat/modeltransformation/atl/lib/presenterLib.atl


I'm using
/com.customer.dat.modeltransformation.startek.atl.lib/src/com/customer/dat/modeltransformation/atl/lib/,/com.customer.dat.modeltransformation.startek/src/com/customer/dat/modeltransformation/startek/atl/files/

as module path in the launch config, and I'm not sure how to modify the library's name and the import in the using module. Can you specify your suggestion further?

Your module path looks fine to me. Can you show me the first few lines of presenterLib.atl?

Cheers,
Dennis

Sure thing:
-- @atlcompiler emftvm
library presenterLib;

--- This is an apparently very general helper which is intended
--- to be used for OclUndefined only.
helper context OclAny def: getSpecification(): String = '';

helper context transformate!MessageModelTransformer def: getSpecification(): String = 
	self.message;

--- Many more of those helpers...


I had a partial success by moving that file to the same directory as the ATL module that uses it: There is no more error message in that case. Instead, just plain nothing happens.

Hi Gunnar, I'm not entirely sure but I think you would need to change the name of your transformations to include the path (at least that's how I made it work for myself), this is what I use:

- Main module:
module "Transformations::RCP2GWTPSM2PIM";
create OUT: UML2 from IN: UML2, Plugin: XML, Profile: profile;
uses "Transformations::Libraries::UMLLibrary";

- Library:
library "Transformations::Libraries::UMLLibrary";


That's the header on each of the ATL files and it works fine for me, hopefully for you too!
