[mdr-users] How to create Associations and AssociationEnd?

Hi,
  I have a requirement in which , I parse the Java source files using
Antlr and then I am trying to convert these parsed classes into Mof
model using MDR and JMI. For doing this I am following UML2MOF source
code (Transform.java). I could create Mofclasses, Operations, class
attributes etc... But I am stuck with how to create an association and
AssociationEnd between the class attributes and MofClass.  Can anyone
guide me on this? And also how is RefAssociation and Association
interfaces are related, if I do
   mofModel.refAllAssociations() ... it will returen RefAssociations.
How do I get Association metaobject from it?

Thanks,
Leena
