Hello.

I am very new to the EMF and all related tooling... So please forgive me if I use some terminology wrong.

Here is what I am trying to do:

Input:
Ecore file (with a model)
A bunch of XML files with models serialized in XMI format that conforms to the ecore file. Basically each XML file is an instance of the model defined by ecore file.

Note: no generated code from the ecore file.

Output/goal:
Import data from all XML files into one repository where each xml file will a separate resource in the repository. I use CDO Hibernate with MySQL as data store.

Here is how I am trying to solve the task:

1) At first I was happy to see that there is org.eclipse.emf.cdo.server.CDOServerImporter.XML and I though that will do what I need. But after reading some posts, it seems that it creates new repository every time and it mostly intended to use for kinda backup/restore use cases. So I gave up on using this.

2) Here is what I am trying to do right now but it fails (see exception below).

Server:

I start with empty MySQL database and lunch CDO server (I took the code from examples, org.eclipse.emf.cdo.examples.hibernate.server). The server starts successfully and I see that some tables are created in MySQL database (like cdo_lob, cdo_package_info, ...).

Client:

On the client I do following:

final CDOSession session = openSession();

OpenSession is like in the example org.eclipse.emf.cdo.examples.hibernate.client except the part where EPackages are registered, because I don't have generated code from the model, I am trying to register EPackaged by reading them from ecore file like this (got the idea from StackOverflow emf-register-ecore-meta-model-programmatically) :

Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap().put("ecore", new EcoreResourceFactoryImpl());

ResourceSet rs = new ResourceSetImpl();
final ExtendedMetaData extendedMetaData = new BasicExtendedMetaData(rs.getPackageRegistry());
rs.getLoadOptions().put(XMLResource.OPTION_EXTENDED_META_DATA, extendedMetaData);

Resource r = rs.getResource(URI.createFileURI("src\\main\\resources\\ECOREFILENAME.ecore"), true);

EPackage[] packages = readPackagesFromEcoreAsResource(r); // just iterate over r.getAllContents() and create an array of eObjects that are instances of EPackage

// Register epackages from ecore file.
for (int i = 0; i < packages.length; i++) {
	session.getPackageRegistry().putEPackage(packages[i]);
}

After that I can see in the console that epackages were registered with correct URIs (the URIs are important because that will be problem later). I am not able to post any URLs in this post because I don't have enough posts on this forum, so in the text below the URI with COMPANYWEBSITE where COMPANYWEBSITE is the url of the company used as namespace.

main [org.eclipse.emf.cdo.internal.common.model.CDOPackageRegistryImpl] Registering COMPANYWEBSITE/sad/dsm --> org.eclipse.emf.ecore.impl.EPackageImpl@1dbe14f (name: ManualDsm) (nsURI: COMPANYWEBSITE/sad/dsm, nsPrefix: dsm)

Then I do following:

final CDOTransaction transaction = session.openTransaction();
CDOResource resource = transaction.getOrCreateResource("/resource1"); 
	
resource.getContents().clear();

final Resource importResource = new XMIResourceImpl();
	      
try (InputStream is = new FileInputStream(new File("src\\main\\resources\\FILENAME.xml"))) {
				
        importResource.load(is, Collections.EMPTY_MAP);
	resource.getContents().addAll(importResource.getContents());

} catch (IOException e1) {
	e1.printStackTrace();
}

Up until now everything seems like working fine. But then when I try to commit the transaction with the following:

	      
try {
        transaction.commit();
} catch (CommitException e) {
	e.printStackTrace();
}

I get errors like this (look at the URIs, they are wrong, they include location of the ecore file):

Please help me to resolve the problem or suggest other way to do the task.

NOT SOLVED, but, by the way, everything works if I generate code from the ecore file and use generated EPackage to register like this:

session.getPackageRegistry().putEPackage(GeneratedModelPackage.eINSTANCE);

So, it seems that the problem is in the place where I register epackages. But I still want to be able to do the task without generating code from ecore file.

Thank you for any help.

Hi Evgeny,

If your resources have cross references among them you simply cannot just load them individually from a stream. You must
use a ResourceSet to load them; otherwise the cross references cannot be resolved. And that's the exception you're seeing.

You should have a look a our resource transfer framework which addresses this challenge. You can test it by using drag
and drop between IResources (all types possible) in your workspace and a CDO repository in the CDO Sessions view. The
underlying framework can be used without that UI.

Cheers
/Eike

Thank you Eike,

I am sorry if what I say doesn't make much send, I am very new to EMF and CDO world.

> If your resources have cross references among them you simply cannot just load them individually from a stream.

So, if I use the same ResourceSet to open all resources, then it might work, right?

I have tried it but still have the same unresovable proxy exception. Here is what I did (I use the same ResourceSet to create both resources, I pass rs variable to openSession method which uses it to create resource):

ResourceSet rs = new ResourceSetImpl();
		
Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap().put(
    "ecore", new EcoreResourceFactoryImpl());
	
Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap().put(
    "xml", new XMIResourceFactoryImpl());

// enable extended metadata
final ExtendedMetaData extendedMetaData = new BasicExtendedMetaData(rs.getPackageRegistry());

rs.getLoadOptions().put(XMLResource.OPTION_EXTENDED_META_DATA, extendedMetaData);
		
final CDOSession session = openSession(rs, "src\\main\\resources\\ECOREFILENAME.ecore");
		
final CDOTransaction transaction = session.openTransaction();
// get/create a resource

CDOResource resource = transaction.getOrCreateResource("/resource1"); //$NON-NLS-1$
	
// clear any previous data
resource.getContents().clear();
	      
final Resource importResource = rs.getResource(URI.createFileURI("src\\main\\resources\\FILENAME.xml"), true); 
	      
try { 

        resource.getContents().addAll(importResource.getContents());
} catch (Exception e1) {
	// TODO Auto-generated catch block
	e1.printStackTrace();
}

Thank you.

That doesn't make sense to me, but maybe that's because you don't show what your openSession() does exactly. In CDO a
transaction - not a session - is associated with a resource set.

Thank you for your reply. Here is what openSession method does:

protected CDOSession openSession(ResourceSet rs, String ecoreFileLocation)
{
	if (sessionConfiguration == null)
	{
	      initialize();
	}

	CDONet4jSession cdoSession = sessionConfiguration.openNet4jSession();
	    
	Resource r = rs.getResource(URI.createFileURI(ecoreFileLocation), true);
		
	EPackage[] packages = readPackagesFromEcoreResource(r);
	    
	for (int i = 0; i < packages.length; i++) {
		 cdoSession.getPackageRegistry().putEPackage(packages[i]);
	}
	    
        return cdoSession;
}

private static EPackage[] readPackagesFromEcoreResource(Resource resource) {
		
	List<EPackage> ePackages = new ArrayList<EPackage>();

	TreeIterator<EObject> treeIter = resource.getAllContents();
	while(treeIter.hasNext()){
		EObject eObject = treeIter.next();
		if (eObject instanceof EPackage) {
			EPackage p = (EPackage)eObject;
		        ePackages.add(p);
		}
	}
		
	return ePackages.toArray(new EPackage[] {});
}

protected void initialize()
{
	    OMPlatform.INSTANCE.setDebugging(true);
	    OMPlatform.INSTANCE.addLogHandler(PrintLogHandler.CONSOLE);
	    OMPlatform.INSTANCE.addTraceHandler(PrintTraceHandler.CONSOLE);

	    // Prepare container
	    final IManagedContainer container = ContainerUtil.createContainer();
	    Net4jUtil.prepareContainer(container); // Register Net4j factories
	    TCPUtil.prepareContainer(container); // Register TCP factories
	    CDONet4jUtil.prepareContainer(container); // Register CDO factories
	    // LifecycleUtil.activate(container);
	    container.activate();

	    // Create connector
	    final IConnector connector = TCPUtil.getConnector(container, CONNECTION_ADDRESS);

	    // Create configuration
	    sessionConfiguration = CDONet4jUtil.createNet4jSessionConfiguration();
	    sessionConfiguration.setConnector(connector);
	    sessionConfiguration.setRepositoryName(REPO_NAME);
}

Hi Evgeny,

it seems to be a problem with dynamic packages, but without the actual packages I can't tell what it is. Can you attach
an executable version of your project so that I can analyze the problem? If you can't post it to the public you could
send a zip to me privately.

Cheers
