[MOFScript] Problem with metamodel setting in Java integration [message #47048]

Hi,

I'm defining some textual tranformations for models based on the
JavaAbstractSyntax metamodel. It works fine! However, when I try to
integrate my MOFScript transformation in a Java environment, using the
example given in the MOFScript User Guide v0.6, it doesn't work.

The following line
**int errorCount = ParserUtil.getModelChecker().getErrorCount();**
returns 85 erros. They are all concerning the lack of a metamodel
definition.

I see that the exemple in the User Guide doesn't present a means of
setting the metamodel before calling
**execMgr.executeTransformation();**
So, the errors are expected.

Although I've searched a lot, I have not found any way of setting the
metamodel, any kind of MOFScript API and any other kind of ducumentation.

Has anyone had the same problem? May someone help me?

Best regards!

The output I get from my Java program is this:
Parsing result: 85 errors
: Error: MTTParseError: Illegal/unknown context: jast, line: 484,
column: 0
: Error: MTTParseError: Can't find feature 'interface' for type
'TypeDeclaration'., line: 28, column: 5
: Error: MTTParseError: Type not found: 'FieldDeclaration' in metamodel
'null', line: 0, column: 0
: Error: MTTParseError: Can't find feature 'bodyDeclarations' for type
'TypeDeclaration'., line: 31, column: 2
: Error: MTTParseError: Type not found: 'MethodDeclaration' in
metamodel 'null', line: 0, column: 0
.

jast is a reference to the metamodel.

Hi,

I think I have hust had the same problem, what I think you should do, is
to register the metamodel you are using.

It would be something like the following:

File metamodel = new File("the metamodel location");
ResourceSet rsSource = new ResourceSetImpl();
rsSource.getResourceFactoryRegistry().getExtensionToFactoryM ap().put( "*",
new XMIResourceFactoryImpl());
Resource resSource =
rsSource.getResource(URI.createFileURI(metamodel.getAbsolute Path()), true);
EPackage paquete = (EPackage) resSource.getContents().get(0);
EPackage.Registry.INSTANCE.put("Uri of the metamodel", paquete);

Good Luck!
