Hi I have a problem in serializing my EMF objects to a XML file.
I want to serialize all Objects but my program create a xml file with only one object in it.

Look on my code:

public void serialize() throws IOException {

ResourceSet rs = new ResourceSetImpl();

// Register the base XML resource factory implementation in the local resource factory registry.

rs.getResourceFactoryRegistry().getExtensionToFact oryMap().put( "xml", new XMLResourceFactoryImpl());
URI fileURI = URI.createFileURI( FILE.getAbsolutePath());

Resource resource = rs.createResource( fileURI);
// serialize all ComputerResources objects into xml
Iterator<ComputerResources> itr = ComputerCollectionGenerator.computerResoucres.iter ator();
while ( itr.hasNext()) {
ComputerResources next = itr.next();
resource.getContents().add( next);
}
resource.save( null);

The objects are created and stored at runtime in ArrayList computerResoucres.

What do I have to do?

Thank you in advance

A XMLResource can only contain a single root element. Use a XMIResource
instead.

The easiest way to do it is 1/ register XMIResourceFactoryImpl with the
".xmi" extension and 2/ end your URI with ".xmi". That's it :-)

Cyril
