Hi,
I'm launching a transformation by code and I have an static model that it
is in plugins. I load this model,
catalogModel = emfamh.loadModel("IN", catalogMM,
URI.createPlatformPluginURI(pluginName + "/models/My.rulescatalog", true));
and then I launch ATL transformation, it throws an error.
If I load this model from workspace,
catalogModel = emfamh.loadModel("IN", catalogMM,
URI.createPlatformResourceURI("/proves/My.rulescatalog", true));
transformation is correct !!!
Question is, can I execute an ATL transformation and load a model that it
is in eclipse plugins ?¿?
Thanks!

Hello, the answer is yes (I'm using it lately).
I have the following
String PLATFORM_RESOURCE = "platform:/plugin/";
String rootAtlPath = PLATFORM_RESOURCE + Activator.PLUGIN_ID+"/";
String atlTransformationPath = rootAtlPath + "atl/transformation.asm";
// the above will create a string like this
// "platform:/plugin/plugin_id/atl/transformation.asm"
// which you load as follows
ASMModel model = emfamh.loadModel("modelName", metamodel, (new URL(atlTransformationPath)).openStream());
....
take care the metamodel to be the model of the model that you want to load and if in turn is a metamodel then use the
following:
metamodel = emfamh.getMof()
this works fine to me.
regards,
christos...

Hi,
I don't know if you have understood me.
What I want to load is an input model to transformation that I have into
plugins, not in workspace.
I have tried it with an input uml model and it works correctly but, when I
try to do this with another model, transformation is executed but it
throws an error:
GRAVE: ****** BEGIN Stack Trace
GRAVE: message: feature name does not exist on CATALOG!EObject
GRAVE: A.main() : ??#28 null
GRAVE: local variables = {self=catalog2configuration : ASMModule}
GRAVE: local stack = []
GRAVE: A.__exec__() : ??#28 null
GRAVE: local variables = {e=TransientLink {rule =
'ConfigurationPattern2ConfiguredPattern', sourceElements = {i =
IN!<unnamed>}, targetElements = {}, variables = {}},
self=catalog2configuration : ASMModule}
GRAVE: local stack = []

NTransientLink;) : ??#31 299:4-299:30

GRAVE: ****** END Stack Trace
INFO: Execution terminated due to error (see launch configuration to allow
continuation after errors).
GRAVE: feature name does not exist on CATALOG!EObject
java.lang.RuntimeException: feature name does not exist on CATALOG!EObject
...
What could be happening ?¿?
Thanks!!!

Hello Miguel,
As Christos told you, yes it is possible.
His example show you how to load a model from a plugin (so this model
cannot be in workspace).
And in your first message, you initialized correctly your URI.
URI.createPlatformPluginURI(<plugin id>/<resourcePath>, false)
Here is an example of what I did :
String kdmMMpath ="org.omg.kdm/model/kdm.ecore";
// plugin id = org.omg.kdm, and resource path = /model/kdm.ecore
// load metamodel
ASMModel kdmMM = modelHandler.loadModel(
"KDM", modelHandler.getMof(),
URI.createPlatformPluginURI(this.kdmMMpath, false));
//Load model instances
ASMModel kdmModel = modelHandler.loadModel("input_kdm", kdmMM,
kdm_Model.getURI());
It is not so far from what you did, yet your stack trace show another
error (your model seems to be correctly loaded) :
GRAVE: ****** BEGIN Stack Trace
GRAVE: message: feature name does not exist on CATALOG!EObject
==> your metamodel is perhaps not correctly loaded. ATL did not find
attribute name in your Catalog element.

But, what you are loading with URI.createPlatformPluginURI() is not an
instance model, it is the metamodel !!!!!
----------------- YOUR EXAMPLE ------------------------
// load metamodel
ASMModel kdmMM = modelHandler.loadModel(
"KDM", modelHandler.getMof(),
URI.createPlatformPluginURI(this.kdmMMpath, false));
//Load model instances
ASMModel kdmModel = modelHandler.loadModel("input_kdm", kdmMM,
kdm_Model.getURI());
----------------- MY EXAMPLE --------------------------
// load metamodel
ASMModel catalogMM = modelHandler.loadModel(
"CATALOG", modelHandler.getMof(),
CATALOGnsUri);
// load model instance
ASMModel catalogModel = modelHandler.loadModel("IN", catalogMM,
URI.createPlatformPluginURI(plugin + "/models/UML2DB.rulescatalog",
true));
As you can see, what I do it is to load the instance model from plugin and
not the metamodel.
Problem is not in loading the model, it is when I launch transformation.

Hello Miguel,
I've tried to load a model (and not a meta model :-)).
And it seems that you have perhaps found a bug :
It works if model is in an other plugin. Yet if the model is located in
plugin where you write your code : it fails !
To have the good behavior when code and model are located in same plugin,
instead of using URI.createPlatformPluginURI, you can use :
Bundle bundle = Platform.getBundle("your plugin id");
URL fullPathString = bundle.getEntry("path of your model");
URI inputUri = URI.createURI(fullPathString.toString());
I hope it will help.
But, what you are loading with URI.createPlatformPluginURI() is not an
instance model, it is the metamodel !!!!!
----------------- YOUR EXAMPLE ------------------------
// load metamodel
ASMModel kdmMM = modelHandler.loadModel(
"KDM", modelHandler.getMof(),
URI.createPlatformPluginURI(this.kdmMMpath, false));
//Load model instances
ASMModel kdmModel = modelHandler.loadModel("input_kdm", kdmMM,
kdm_Model.getURI());
----------------- MY EXAMPLE --------------------------
// load metamodel
ASMModel catalogMM = modelHandler.loadModel(
"CATALOG", modelHandler.getMof(),
CATALOGnsUri);
// load model instance
ASMModel catalogModel = modelHandler.loadModel("IN", catalogMM,
URI.createPlatformPluginURI(plugin + "/models/UML2DB.rulescatalog",
true));
As you can see, what I do it is to load the instance model from plugin and
not the metamodel.
Problem is not in loading the model, it is when I launch transformation.
