| Trying to call Generated Ecore Model Code from Java Application [message #490038] |

I created an Ecore model and used the Generator to generate the Model,
Edit, and Editor. I create an instance of the Ecore Model in the Editor
and persisted it to the default XMI format. I exported the model package.
I need to access this Model code and XMI instance from a Webservice. I
have created a Java class which creates a ResourceSet and tries to load
the XMI instance. I get this error:
Here is the code in the Java method:
ResourceSet resourceSet = new ResourceSetImpl();
resourceSet.getResourceFactoryRegistry().getExtensionToFacto ryMap()
.put("sizing", new XMIResourceFactoryImpl());
URI uri = URI.createFileURI("c:/Applications.sizing");
Resource resource = resourceSet.getResource(uri, true);
When I debug it throws a error at this line:
Resource resource = resourceSet.getResource(uri, true);
The first two lines of the XMI file are:
<?xml version="1.0" encoding="ASCII"?>
<xmi:XMI xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI"
xmlns:sizing="http://www.oracle.com/esg/sizing.ecore/1.0.0">

Did you look the XyzExample.java that's generated in the *.tests project
if you invoke "Generate Test Code"?

Yes, the package isn't registered automatically when you're not running
in OSGi, so an idiom to use is to invoke XyzPackage.eINSTANCE.eClass()
which registers the package as a side effect.
