Need an example of MDR usage

[Jess.Singh]

Hi I need to generate JMI interfaces from a uml1.4 xmi file exported by
argo uml. The code below throws class cast exception when i try to cast
umlMetaModel to ModelPackage in the for loop.
  Alternatively can anyone point me to a basic example of programmatic JMI
interface genreation using MDR.

Thanks,
JS

public class MyMDR {

      /**
       * @param args
       */
      public static void main(String[] args) {

            MDRManager manager = MDRManager.getDefault();
            MDRepository repository = manager.getDefaultRepository();
            XMIReaderFactory factory = XMIReaderFactory.getDefault();
            XMIReader reader = factory.createXMIReader();
            RefPackage umlMetaModel;
            repository.beginTrans(true);

            try {
                  // put the UML metamodel into MDR

                  FileInputStream in = new FileInputStream(
                              "/xmi/01-02-15.xml");
                  umlMetaModel = repository.getExtent("UML-MetaModel");


                  MofPackage umlPackage = null;
                  for (Iterator it = ((ModelPackage)
umlMetaModel).getMofPackage()
                              .refAllOfClass().iterator(); it.hasNext();) {
                        MofPackage temp = (MofPackage) it.next();
                        if ("UML".equals(temp.getName())) {
                              umlPackage = temp;
                              break;
                        }
                  }

                  RefPackage umlInstance = repository.createExtent(
"umlInstance",
                              umlPackage);

                  JMIMapper mapper = JMIMapper.getDefault();

                  mapper.generate(new FileStreamFactory(new File(".")),
umlInstance);
            } catch (Exception e) {
                  e.printStackTrace();
            }

      }

}

Hi Jess,
you can generate JMI interfaces from MOF models only. JMI defines
MOF->Java mapping, not UML 1.4->Java mapping.
One thing you could do is to convert your UML 1.4 model to a MOF model
(using UML2MOF tool - see http://mdr.netbeans.org/uml2mof) - you just
need to make sure your UML model conforms to UML Profile for MOF defined
on the UML2MOF web page).
Then you can generate JMI interfaces from that MOF model.
