Feature not found loading serialized resource [message #423831]

I have created a emf project from a set of xsds and I'm trying to load a
serialized resource. I have generated the model code and the test code.
I am able to save a resource to an xml file without any problem, but when
I try to load that xml file, I get a FeatureNotFoundException. I am using
the generated resource factories and registering the ePackage prior to
calling getResource(). I was following the example code in
xxxExample.java generated with the test code.

Save code( pjcpr was created from TcfPackage.eINSTANCE.createXXX() ):

ResourceSet resourceSet = new ResourceSetImpl();
resourceSet.getResourceFactoryRegistry().getExtensionToFacto ryMap().put( "tcf",
new TcfResourceFactoryImpl());
resourceSet.getPackageRegistry().put(TcfPackage.eNS_URI,
TcfPackage.eINSTANCE);
File file = new File(fileName);
URI uri = URI.createFileURI(file.getAbsolutePath());
Resource resource = resourceSet.createResource(uri);
resource.getContents().add(pjcpr);
resource.save(Collections.EMPTY_MAP);

Load code:
ResourceSet resourceSet = new ResourceSetImpl();
resourceSet.getResourceFactoryRegistry().getExtensionToFacto ryMap().put( "tcf",
new TcfResourceFactoryImpl());
resourceSet.getPackageRegistry().put(TcfPackage.eNS_URI,
TcfPackage.eINSTANCE);
File file = new File(fileName);
URI uri = URI.createFileURI(file.getAbsolutePath());
Resource resource = resourceSet.getResource(uri, true);
System.out.println("loaded " + resource.getContents().size() + " resources
from " + file.getAbsolutePath() );
PlotterJobCpr pjcpr = (PlotterJobCpr)resource.getContents().get(0);

Exception thrown when calling getResource():
org.eclipse.emf.ecore.xmi.FeatureNotFoundException: Feature
'PlotterJobCpr' not found.
(file:/Users/calibrate/src/eclipsedev/TestModeling/test/-145 0256654009633910.tcf,
2, 62)

First few lines of -1450256654009633910.tcf:
<?xml version="1.0" encoding="ASCII"?>
<tcf:PlotterJobCpr xmlns:tcf="http://www.kodak.com/2008/TCF">
<tcf:plotterId>-1450256654009633910</tcf:plotterId>
<tcf:plotterName>ebdfa741c89bf38a</tcf:plotterName>
<tcf:plotterJobDefId>-1450256654009633910</tcf:plotterJobDefId >
...

I am using Eclipse 3.4.0 and EMF 2.4.0. Any help you can give would be
appreciated.

Is there a document root needed?

I'll bet you need to use

DocumentRoot documentRoot = TcfFactory.eINSTANCe.createDocumentRoot();
documentRoot.setPJCPR(pjcpr)

and add the document root to the resource rather than directly an
instance of a complex type. (Like the generated example does.)
