HOW to register UML resources? [message #631318] Wed, 06 October 2010 23:31 Go to next message

I am already have a ecore parser with OCL ,so I always want to do little change to parser UML with OCL.
But so far , it seems more difficult than ecore .
In ecore:
ResourceSet resourceSet = new ResourceSetImpl();
resourceSet.getResourceFactoryRegistry().getExtensionToFacto ryMap().put(
"ecore", new EcoreResourceFactoryImpl());

URI myEcoreURI = URI.createFileURI(file.getAbsolutePath()); //file is .ecore file.
Resource myEcoreResource = resourceSet.getResource(myEcoreURI, true);

i can easily get my resource.

But in UML:
resourceSet.getPackageRegistry().put(UMLPackage.eNS_URI, UMLPackage.eINSTANCE);
resourceSet.getResourceFactoryRegistry().getExtensionToFacto ryMap().put( "uml", new UMLResourceFactoryImpl());
URI UMLuri = URI.createFileURI(umlfile.getAbsolutePath()); umlfile is .uml file.
***Resource resource = resourceSet.getResource(UMLuri, true);

I got exception about my resources...OH my goodness!

Exception in thread "main" java.lang.NoSuchMethodError: org.eclipse.emf.ecore.resource.URIConverter.createInputStrea m(Lorg/eclipse/emf/common/util/URI;Ljava/util/Map;)Ljava/io/ InputStream;

Hutzu,

A NoSuchMethodError exception means the client code (in this case, UML2) was compiled against a version of the provider code (in this case, EMF) that defined the method, but it is being run against another that does not have the method.

You need to ensure you use a UML2 version that matches the EMF version you are using.

See:

http://www.eclipse.org/modeling/mdt/downloads/?project=uml2

for the available UML2 versions and the corresponding build dependencies (at least for more recent UML2 releases).

Cheers,

Rafael

Thanks a lot,Rafael
it really work~

My objective is to parse class diagram with OCL.
In ecore , first i need to parse ecore diagram to get "ArrayList<EPackageImpl> ".
shall i do the same thing in UML2 class diagram?

To write a parser to get ArrayList<EPackageImpl> , and then register the UML2
am i right?

best regards
hutzu
