How to combine Teneo with Jet? [message #63409]

Hello,

My application needs to generate code out of a very huge model
(thousands of classes). Since loading everything into memory is not an
option, I think Teneo will suit best. I am able to run JET
transformation in Java using Jet2Platform.runTransformOnResource() by
specifying a XMI file, but how can I run a Jet transformation on a
ResourceSet object?

I want to load the huge model from the database as a ResourceSet
(through EMF/JPOX resources) and then run a JET transformation.

Thanks in advance,
Kalin

Hi Kalin,
I think that this is more a Jet question then a Teneo question. I have not used Jet in this way so I
hope Paul can answer it.

Kalin:

Sorry, I didn't notice your post sooner...

You'll have to pardon my ignorance of Teneo details, I have only scanned the
tutorial, but here goes...

As you note, JET2Platform.runTransfornOnResource() works on an Eclipse
IResource, something you won't have if using Teneo. But all
JET2Platform.runTransformOnResource() does is load the EMF resource for the
IResource, and then pass the loaded EMF Resource off to the execution
engine.

Try the following:

1) Load the Teneo-based resource. Here's the snippet from the Teneo/JPOX
tutorial:
String uriStr = "jpox://?" + JPOXResource.DS_NAME_PARAM + "=MyPMF";
final URI uri = URI.createURI(uriStr);
ResourceSet resourceSet = new ResourceSetImpl();
final Resource res =
resourceSet.createResource(uri);res.load(Collections.EMPTY_M AP);2) Pass the
loaded resource to JET2Platform.runTransformOnObject();

JET2Platform.runTransformOnObject("...id", res, progressMonitor);

If Teneo delivers as promised, then JET should have not problem navigating
your model.

Thank you very much for the help, it works that way. One note - I just
had to define the org.eclipse.jet.resource.project.name variable when
using runTransformOnObject(), otherwise it throws exception for the
undefined variable.

Kalin:

Good to hear it worked - kudo's go to Teneo for that.

To predefine variables for a JET transformation, you can pass in a map:

Map variables = new HashMap();
variables.put("org.eclipse.jet.resource.project.name", ...);
JET2Platform.runTransformOnObject("... jet id ..", res, variables, ..
progress montitor ...);
