Hello,
I am unable to figure out how to properly work with non-containment references when serializing and loading it. Please consider the following example (based on
www.theserverside.com/news/1364302/Binding-XML-to-Java). This output:
<?xml version="1.0" encoding="ASCII"?>
<tree:rootNode xmlns:tree="http://www.eclipse.org/emf/example/dom/Tree" label="rootNode" references="./document.xml#ref">
<tree:childNode label="childNode"/></tree:rootNode>
was produced by the following code:
ResourceSet resourceSet = new ResourceSetImpl();
// Register XML Factory implementation to handle .xml files
resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap()
.put("xml", new XMLResourceFactoryImpl());
// Create empty resource with the given URI
Resource resource = resourceSet.createResource(URI
.createURI("./document.xml"));
//create instances
DocumentRoot documentRoot=TreeFactory.eINSTANCE.createDocumentRoot();
TreeNode rootNode=TreeFactory.eINSTANCE.createTreeNode();
rootNode.setLabel("rootNode");
documentRoot.setRootNode(rootNode);
TreeNode treeNodeRef=TreeFactory.eINSTANCE.createTreeNode();
treeNodeRef.setLabel("ref");
TreeNode childNode=TreeFactory.eINSTANCE.createTreeNode();
childNode.setLabel("childNode");
rootNode.getChildNodes().add(childNode);
rootNode.getReferences().add(treeNodeRef);
//add object to resource
resource.getContents().add(documentRoot);
//add non containment reference to the source
resource.getContents().addAll(rootNode.getReferences());
//use ext metadata
options.put(XMLResource.OPTION_EXTENDED_META_DATA, Boolean.TRUE);
//save (stdout)
((XMLResource)resource).save(System.out, options);
//save to DOM document
Document doc=((XMLResource)resource).save(null, options, null);
Question: How I have to correctly resolve this reference, because when loading it:
//load
XMLResource resource1 = new XMLResourceImpl();
resource1.load(doc, options);
DocumentRoot documentRoot1= (DocumentRoot) resource1.getContents().get(0);
System.out.println(((TreeNode)rootNode.getReferences().get(0)).getLabel());
System.out.println(((TreeNode)documentRoot1.getRootNode().getReferences().get(0)).getLabel());
I only get null for its label attribute.
As one can see, in the above xml output, the references attribute points to "./document.xml#ref". So how can I add this "#ref" to the document ?
Or the other way around: what I am missing ?
Thanks a lot,
Marian

This reference looks odd. I don't generally expect a "." in a URI
formed by EMF when using URI.deresolve between two absolute URIs. That
makes me think you probably are not using absolute URIs when loading
your document.

There you go. This should be an absolute URI if you want cross
document references to be properly converted to relative URIs. I.e.,
URI.createFileURI(new File("document.xml").getAbsolutePath())

In this case, you're even loading a resource that doesn't know its own
URI and it's not even in a resource set, so it won't be able to resolve
any cross document references. And because you

Ensure that all your resources have an absolute URI before you save then
and load them with an absolute URI as well.
Generally you're best off to use a resource set.
If you have a simple model lying around, I'd suggest invoke Generate
Tests and have a look at the generated XyzExample.java to see how best
to save and load resources in a stand alone application.

Thanks for your comments.

There you go. This should be an absolute URI if you want cross
document references to be properly converted to relative URIs. I.e.,
URI.createFileURI(new File("document.xml").getAbsolutePath())
I am wondering if I really have to go with a cross-document reference. (why not just put the reference in to the same document ?) Is it correct that in this case I have to create, save and load 2 resources, and reference the content of B in A.
I did something like this: (The resourceset I am creating as you suggested in the same way as it is created in the generated test code (TreeExample.java) and I am now using absolute URI as you suggested.)
// Create a resource set to hold the resources.
ResourceSet resourceSet = new ResourceSetImpl();
// Register the appropriate resource factory to handle all file extensions.
resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put
(Resource.Factory.Registry.DEFAULT_EXTENSION,
new TreeResourceFactoryImpl());
// Register the package to ensure it is available during loading.
resourceSet.getPackageRegistry().put(TreePackage.eNS_URI,
TreePackage.eINSTANCE);
Resource resource = resourceSet.createResource(
URI.createFileURI(new File("document.xml").getAbsolutePath()));
Resource resourceRef = resourceSet.createResource(
URI.createFileURI(new File("treeNodeRef.xml").getAbsolutePath()));
//create and init instances
...
//add instance documentRoot
resource.getContents().add(documentRoot);
resourceRef.getContents().add(treeNodeRef);
//save instances
//save to file
((XMLResource)resource).save(options);
((XMLResource)resourceRef).save(options);
Now I have a problem with loading. I want to test loading with a fresh resourceSet, (assuming that I usually cannot use the resourceSet instance used for serializing), and tried this code:
//set up the resourceset (new instance for loading) as before
ResourceSet resourceSetLoad = new ResourceSetImpl();
...
//create resources:
Resource resourceLoad = resourceSetLoad.createResource(
URI.createFileURI(new File("document.xml").getAbsolutePath()));
Resource resourceRefLoad = resourceSetLoad.createResource(
URI.createFileURI(new File("treeNodeRef.xml").getAbsolutePath()));
//load
((XMLResource)resourceLoad).load(options);
((XMLResource)resourceRefLoad).load(options);
The last line (loading resourceRefLoad) produce the exception:
Exception in thread "main" org.eclipse.emf.ecore.resource.Resource$IOWrappedException: Feature 'TreeNode' not found. (file:/usr/home/heinz/workspace/BindingXMLJava/org.eclipse.emf.example.dom/treeNodeRef.xml, 2, 86)

What is the purpose of this? A document's elements can't be contained
by a different resource. I'm sure you don't really want to achieve
cross document containment, which is supported, but doesn't make sense
for this case.

OK, I am now able to manage xml serialization (with non containment references in to one document/resource), based on a simple emf model (two classes, one is noncontainment referenced by the other using multiplicity many), that doesnt have any annoations, and just one default package. The output is what I would expect.
Thanks so far again for your help.
Edit 1: Just noticed that I have serialized as xmi
