Hi everybody,
I created an ATL PROJECT which runs successfully.Now I would like to do the transformation by using the a project which its type is "Plugin ATL".
I created it and and I chose the ATL launch configuration the one related to the first ATL project.The CREATION of the ATL plugin is done sccessfully.My problem now is in tha java class generated by the plugin.it is like this:

My question is where can I place the metamodels(in format "ecore")and the models (in format .xmi).I mean their path because I place them in the plugin.What are my errors.


Please help me and I will be thankful very much Smile

Hello,

There is no specific place to put your models and metamodels, it's up to you to decide.

According to your choice, the paths of the input/output metamodels can be set via the generated ".properties" file.
The paths of the input/output models are determined when calling to the generated loadModels and saveModels methods.

Thank you but the action of loading doesn't work.I place my models "sample-Families.xmi" which is not empty and "sample-Persons.xmi" which is empty in the same project "org.eclipse.m2m.atl.Families2Persons".

the file of Families2Persons.properties seems like this:

Families2Persons.modules = Families2Persons.atl

# Metamodels paths or nsUris
Families2Persons.metamodels.Families = /Families2Persons/Families.ecore
Families2Persons.metamodels.Persons = /Families2Persons/Persons.ecore



# Libraries paths

# ATL Launching options



==>I need to find a solution the loading of models doesn't work.Can body tell me how can I do to solve the problem of loading.My program doesn't work and the console seems like this:

You don't need to create manually any Persons model as it is going to be produced by the transformation (what you have to provide is just a String expressing the selected path).
Concerning the metamodels and input model, you have to check that the provided paths/URIs are actually correct (and that the corresponding IDs are right in the properties file).
If everything is set correctly, then it should work properly.

Please Mr.Hugo help me more:as the file "Families2Persons.properties" the Paths of both metamodels are:

Families2Persons.metamodels.Families = /Families2Persons/Families.ecore
Families2Persons.metamodels.Persons = /Families2Persons/Persons.ecore

The path of the inModel is "/org.eclipse.m2m.atl.Families2Persons/src/sample-Families.xmi"

Could you show me where exactly can me place the paths in the code and thank you so much Smile

As written in the generated code, you have to provide the input model path when calling to the loadModels method.

I'm still having problems with Plugin ATL.. I'm using exactly the same example Families2Persons. It works fine without the programmatically way of trying.

"O sistema não pode encontrar o caminhado especificado" means The system couldn't find the specified path.

The thing here is.. I'm having troubles to load even the metamodel. They are in another project.. but I checked the .properties files and the key/id is fine. I tried to copy the metamodels to my project called "org.eclipse.m2m.atl.Families2Persons" and change the .properties file to match but even like this.. not working.

Any Help please. Thanks in advance!

I am having the same problem. When I try to set the metamodel path in the .properties file I am getting the same error.

My atl Plugin structure looks like this
- es.berrio.atl (plugin)
+ es.berrio.atl.files (package)
- Vehicle2cars.java
- vehicle2cars.asm
- vehicle2cars.atl
- vehicle2cars.properties
+ metamodels (folder)
- vehicle.ecore
- cars.ecore

I have tried to change the path in the vehicle2cars.properties file, but with no success. I how should I specify this path?

I would appreciate any help

Regards!
