[news.eclipse.modeling.gmt] Re: [MOFScript] loading Metamodel

[waldemar.neto@xxxxxxxxx (Netuh)]

Thanks Gøran,

i did it...

File metamodel = new File("Z:\\<<Filepath>>\\JavaAbstractSyntax.ecore");
ResourceSet rsSource = new 
ResourceSetImpl();		rsSource.getResourceFactoryRegistry().getExtensionToFactoryMap().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.getSourceMetaModelName(ExecutionManager.java:887)
	at 
org.eclipse.mofscript.runtime.ExecutionManager.loadSourceModel(ExecutionManager.java:585)
	at code.JavaCodeGeneration.test(JavaCodeGeneration.java:123)
	at code.JavaCodeGeneration.main(JavaCodeGeneration.java:151)

Any ideia?

Thanks in advance
