Hi everybody,
I know this may be a too simple question, but I just started playing with EMF and MDT UML2, evaluating the technology for usage in a future project.
I noticed that I can't save the model to an XMI/XML file with a code like this (or any other alternative found):
protected static void save(org.eclipse.uml2.uml.Package package_, URI uri) {
ResourceSet resourceSet = new ResourceSetImpl();
// This is in a separate guarded routine to isolate the compilation error
// from invoking a MDT/UML2 4.0.0 routine on MDT/UML2 3.0.0
org.eclipse.uml2.uml.resources.util.UMLResourcesUtil.init(resourceSet);
Resource resource = resourceSet.createResource(uri);
if (resource != null) {
if (resource.getContents() != null) {
resource.getContents().add(package_);
try {
Resource.Factory.Registry reg = Resource.Factory.Registry.INSTANCE;
Map<String, Object> map = reg.getExtensionToFactoryMap();
map.put("epo2", new XMIResourceFactoryImpl());
resource.save(System.out, null);
out("Done saving " + package_.getName() + " at URI " + uri);
} catch (IOException ioe) {
err(ioe.getMessage());
}
}
else
err("Unable to save " + package_.getName() + " using URI " + uri
+ " since resource contents is null");
}
else
err("Unable to save " + package_.getName() + " using URI " + uri
+ " since resource is null");
}
since I always get that resource is null. But no other message.
I attached the whole example (constructed by following http://wiki.eclipse.org/MDT/UML2/Getting_Started_with_UML2 tutorial.
I'm using Eclipse Juno SR1 with Oracle JDK 1.7 and MDT-UML2 4.0.1.
Can somebody tell me what is missing? Or what else should I do to make it work?
Any help is greatly appreciated.
Many thanks in advance!

Hi
Please use the UML2 newsgroup for UML2 discussions.
The introduction of UML 2.4 support has caused some difficulties in
ensuring compatibility with older UML
versions;https://bugs.eclipse.org/bugs/show_bug.cgi?id=389542
The final, least bad resolution was arrived at after SR1 and so you need
to use the maintenance branch from GIT, or a recent I-Build.
The problem lies variously in the
Resource resource = resourceSet.createResource(uri);
or the underlying registrations. With SR1, you need to add a global
registration:
Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap().put(
UMLResource.FILE_EXTENSION, UMLResource.Factory.INSTANCE);
You should remove this once you use SR2. If you are also using pre-UML
4.0.0 nsURI models you must use the latest GIT/I-Build.
Regards
Ed Willink
