I am using EMF in a standalone application. I am getting the following error:

java.lang.RuntimeException: Cannot create a resource for 'file:/C:/Vishnu/Work/runtime-Rule_test/testRule/xsd/CreditCard.xsd'; a registered resource factory is needed
at org.eclipse.emf.ecore.resource.impl.ResourceSetImpl.getResource(ResourceSetImpl.java:394)
at com.sap.server.TestMain.main(TestMain.java:63)

CODE:

private static List<XSDSchema> loadXSDSchema() throws FileNotFoundException
{
List<XSDSchema> schemas=new ArrayList<XSDSchema>();
//resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put("xml", new XMLResourceFactoryImpl());
Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap().put("xml", new XMLResourceFactoryImpl());
ResourceSet resourceSet = new ResourceSetImpl();
try {
Resource resource = resourceSet.getResource(URI.createFileURI("C:/Vishnu/Work/runtime-Rule_test/testRule/xsd/CreditCard.xsd", true);
if(resource instanceof XSDResourceImpl)
{
XSDResourceImpl xsdResource = (XSDResourceImpl) resource;
// The contents of the resource is the root XSDSchema object
schemas.add(xsdResource.getSchema());
}
}catch(Exception e){
e.printStackTrace();
}
return schemas;
}

Can someone please help me on this. I am completely new to EMF and any help in this issue will be helpful.Thank you.

You'll want to add this 
<blockquote>resourceSet.getURIConverter().getResourceFactoryRegistry().getExtensionToFactoryMap().put("xsd",
new XSDResourceFactoryImpl()); 
</blockquote>
Or do this, but only in a stand alone application, not when running
as a plugin: 
<blockquote>Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap().put("xsd",
new XSDResourceFactoryImpl()); 
</blockquote>
You shouldn't need to cast to XSDResourceImpl; you can do
resource.getContents().get(0) and test if that's an XSDSchema.

Thank you so much Ed Merks. It worked... Smile

I replaced Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap().put("xml",
new XMLResourceFactoryImpl()); with Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap().put("xsd", new XSDResourceFactoryImpl());

Thanks,
Vishnu
