| Validating an EMF model programatically [message #535839] |

Hi everyone, I posted this question a couple of days ago in the UML forum but it seems that I should have used the EMF newsgroup instead, so I'm just moving the message.
------------------------------------------------------------ ----------------------------------------
I was going over the EMF Validation Framework example and I was able to set everything up and add a few extra constraints. Then I run the plugin as an eclipse application, I create the model and then in the editor menu I can select validate to check the constraints and everything works fine.
But I was wondering if it is possible to validate a model programmatically, without using the editor.
// For example, create a few objects:
Book myBook = EXTLibraryFactory.eINSTANCE.createBook();
myBook.setTitle("EMF Validation");
Writer writer = EXTLibraryFactory.eINSTANCE.createWriter();
writer.setName("Hector");
//And then do the validation
I've been searching the web with no luck. Can something like this be done? I would appreciate any hints.
Thanks.

I see, after searching for a while on the internet that seems to be the consensus. I'll see if I can find an alternative. Thanks for your help.

Not all the frameworks support running stand alone. I think you'll need
to run this as an Eclipse application.

Thanks Jonas,
I tried the that approach but it did not work in my example, I get an exception, this is the code I'm using:
University univ = UniversityFactory.eINSTANCE.createUniversity();
ValidationDelegateClientSelector.running = true;
IBatchValidator validator = (IBatchValidator) ModelValidationService.getInstance().newValidator(Evaluation Mode.BATCH);
validator.setIncludeLiveConstraints(true);
IStatus status = validator.validate(univ);
ValidationDelegateClientSelector.running = false;
And the exception:
Exception in thread "main" java.lang.ExceptionInInitializerError
at emf.examples.university.validation.adapter.EValidatorAdapter . <init>(EValidatorAdapter.java:57)
at university.tests.Main.main(Main.java:23)
Caused by: java.lang.NullPointerException
at org.eclipse.emf.validation.internal.EMFModelValidationPlugin .getPluginId(EMFModelValidationPlugin.java:201)

at org.eclipse.emf.validation.service.ModelValidationService.<init >(ModelValidationService.java:134)

... 2 more
