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.

Thanks Gøran,
i did it...
File metamodel = new File("Z:\\<<Filepath>>\\JavaAbstractSyntax.ecore");
ResourceSet rsSource = new
ResourceSetImpl(); rsSource.getResourceFactoryRegistry().getExtensionToFactoryM ap().put( "*",
new XMIResourceFactoryImpl());
Resource resSource = rsSource.getResource(
URI.createFileURI(metamodel.getAbsolutePath()), true);
EPackage package = (EPackage) resSource.getContents().get(0);
EPackage.Registry.INSTANCE.put("JavaAbstractSyntax", package);
But now i have other problem. When i load the model.
i m doing it:
execMgr.lookupAndAddSourceMetaModel("JavaAbstractSyntax","JavaAbstractSyntax "));
execMgr.loadSourceModel(new
File("Z:\\<<Filepath>>\\test.javaabstractsyntax"));
But a exception is thrown. The model test.javaabstractsyntax and the
transfomation works well on the eclipse plugin.
Exception in thread "main" java.lang.NullPointerException
at
org.eclipse.mofscript.runtime.ExecutionManager.getSourceMeta ModelName(ExecutionManager.java:887)

org.eclipse.mofscript.runtime.ExecutionManager.loadSourceMod el(ExecutionManager.java:585)
at code.JavaCodeGeneration.test(JavaCodeGeneration.java:123)
at code.JavaCodeGeneration.main(JavaCodeGeneration.java:151)
Any ideia?
Thanks in advance

Thanks Goran,
i solve my problem making, lookUp my metamodel, registring the
ResourceFactory nad loading my model by archive.
execMgr.lookupAndAddSourceMetaModel("jast", "JavaAbstractSyntax");
execMgr.lookupAndAddSourceMetaModel("JavaAbstractSyntax","JavaAbstractSyntax ");
Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap( ).put( "javaabstractsyntax",
new XMIResourceFactoryImpl()
{
public Resource createResource(URI uri)
{
XMIResource xmiResource = new XMIResourceImpl(uri);
return xmiResource;
}
});
execMgr.loadSourceModel(new File(inputPath));
