Standalone EMF validation not registering constraints [message #660339]

Hi,

I am trying to invoke EMF Validation from my class using
IBatchValidator validator =
(IBatchValidator)ModelValidationService.getInstance().newVal idator(EvaluationMode.BATCH);
ModelValidationService.getInstance().loadXmlConstraintDeclar ations();
validator.setIncludeLiveConstraints(true).

But going forward the constraints in plugin.xml are not invoked.
I was going through posts and found https://bugs.eclipse.org/bugs/show_bug.cgi?id=167972, can someone please give an example of how can I add modeledConstraintProviders extension point, what is the ConstraintResourceURI it is expecting.
I could not find the example in eclipse help content for this extension point

Thanks for your response

The subject line mentions "standalone" but the body of your comment
doesn't mention that. Nor does it contain any question marks. Perhaps
you'd like to spend a little more time formulating a coherent question...

Okay let me ask my question again more clearly:
I am trying to invoke EMF Validation from a standalone jar i.e. it is not being used from within eclipse or eclipse RCP. I have a main method in one of my class from which I am invoking Validation using this code:
// Invoke validation framework as usual
IBatchValidator validator =
(IBatchValidator)
ModelValidationService.getInstance().newValidator(Evaluation Mode.BATCH);
validator.setIncludeLiveConstraints(true);
IStatus status = validator.validate(objs); // where objs is my EObjects to be validated

If I do System.out.println(status), I get "Status OK: org.eclipse.emf.validation code=10 No constraints were evaluated. null" even though Validation error is there.
While trying to investigate the issue, I found this post https://bugs.eclipse.org/bugs/show_bug.cgi?id=167972 where it is stated that EMF Validation 1.4.0 provides standalone support. My question is how to use modeledConstraintProviders extension point to get the constraints registered ? An example will be helpful as to what should be the ConstraintResourceURI in the extension point and the class it will define?

Thanks,
Surekha

So everything that's normally done via extension registrations in the
plugin.xmls will need to be done manually.

I don't know the answer and I'm not sure anyone who does pays attention
to the newsgroup anymore. Wouldn't it be much easier to run a headless
Eclipse instance so that your extensions just work?
