My code is as below:
import org.eclipse.emf.common.util.URI;
import org.eclipse.emf.ecore.EPackage;
import org.eclipse.emf.ecore.resource.Resource;
import org.eclipse.emf.ecore.resource.ResourceSet;
import org.eclipse.emf.ecore.resource.impl.ResourceSetImpl;
//import org.eclipse.emf.ecore.xmi.impl.EcoreResourceFactoryImpl;
import org.eclipse.emf.ecore.xmi.impl.*;
import org.eclipse.hyades.models.symptom.SymptomPackage;
import org.eclipse.hyades.models.symptom.impl.*;
public class hello{
public static void main(String arg[]){
ResourceSet resourceSet = new ResourceSetImpl();
Resource.Factory.Registry registry = resourceSet.getResourceFactoryRegistry();
registry.getExtensionToFactoryMap().put("xml", new XMLResourceFactoryImpl());
SymptomPackage symPack = SymptomPackageImpl.init();
System.out.println(symPack.eNS_URI);
System.out.println(symPack.eINSTANCE);
EPackage.Registry reg = resourceSet.getPackageRegistry();
reg.put(symPack.getNsURI(), symPack);
System.out.println(symPack.getNsURI());
resourceSet.getResource(URI.createFileURI("d:\\symptomdb.xml "), true);
}
}
The error message is as below:
