Hi Martin,
when I select both ecore Models and then generate it is working. 
So the model itself seems to be OK.
Here is my code:
public class TestTeneo {
* @throws IOException
*/
public static void main(String[] args) throws IOException {
TestTeneo tt = new TestTeneo();
tt.run();
}
private void run() throws IOException{
final Properties props = new Properties();
props.setProperty(Environment.DRIVER, "com.mysql.jdbc.Driver");
props.setProperty(Environment.URL, "jdbc:mysql://localhost:3306/Abilit");
props.setProperty(Environment.USER, "root");
props.setProperty(Environment.PASS, "");
props.setProperty(Environment.DIALECT, "org.hibernate.dialect.MySQLInnoDBDialect");
props.setProperty(Environment.SHOW_SQL, "true");
props.setProperty(PersistenceOptions.INHERITANCE_MAPPING, "SINGLE_TABLE");
HbDataStore hbds = (HbDataStore)HbHelper.INSTANCE.createRegisterDataStore("Abilit ");
hbds.setProperties(props);
List<String> packageFiles = new ArrayList<String>();
packageFiles.add(" /Users/torstenlink/Documents/workspace_abilit_java/gumbo/mod el/structure.ecore ");
packageFiles.add(" /Users/torstenlink/Documents/workspace_abilit_java/gumbo/mod el/testModel.ecore ");
EPackage[] packages = readFromEcore(packageFiles);
// at this point the array conmtains two packages as I expect
hbds.setEPackages(packages);
hbds.initialize();
}
// this reeds the ecore File and returns all packages in this file
// Is it necessary to get all Packages of the model file or just
// the top level Packages?
private EPackage[] readFromEcore(List<String> ecoreFiles) {
final ResourceSet resourceSet = new ResourceSetImpl();
resourceSet.getResourceFactoryRegistry().getExtensionToFacto ryMap().put( "*", new EcoreResourceFactoryImpl());
final ArrayList<EPackage> epackages = new ArrayList<EPackage>();
for (String ecoreFile : ecoreFiles) {
try {
final Resource res = resourceSet.getResource(URI.createURI(ecoreFile), true);
TreeIterator<EObject> treeIter = res.getAllContents();
while(treeIter.hasNext()){
EObject obj = treeIter.next();
if (obj instanceof EPackage) {
epackages.add((EPackage) obj);
}
}
} catch (Exception e) {
throw new IllegalStateException(e);
}
}
EPackage[] packArray = new EPackage[epackages.size()];
for(int i=0; i<epackages.size();i++){
packArray[i] = epackages.get(i);
}
return packArray;
}
}
Thanks for the fast Help

Hi Torsten,
Can you check that the read of epackages correctly creates the relations between the epackages. So is the testModel
refering to the structure epackage read first or to a new instance of the structure epackage?
