Respected Sir
As i had told you in my previous mail about the confusion with the use of MDR with respect to my project. Now the confusion is some what cleared.

My Current Status is that i have got the  UML METAMODEL from poseidon's website and i have download and used it to create JMI Interfaces(by using MDR first Instantiating a MOF then importing the UML METAMODEL and generating JMI Interfaces). Now My problem is how to get the Implementation of the hundred of classes using MDR.  I got to know that MDR generates the implementation of the interfaces on the fly by generating byte code for it. But how to i see,access and use these classes.
Can i extend these classes for my project?


If i get these classes then can i instantiate objects of these classes by loading a XMI file of any UML Diagram using MDR. As i have to basically read any UML Diagram XMI to compute Metrics on it.

Thanking you in advance
With regards

Hi Bhakti,

I don't think, You are supposed to subclass the implementations of JMI interfaces. Normally you would only want to interact with the implementation through the JMIs.

 Hi Bhakti,

you can generate "Java Metadata Interfaces", that correspond to the classes
of your metamodel, with the Netbeans-environment. Those interfaces allow the
access to the appropriate objects,that are generated on the fly by the
NBMDR. Therefore you have to compile the generated interfaces and put them
into a "jar-File". If you are working with the NBMDR that is integrated
Netbeans-environment you must write a special manifest for that jar-file.
There is an example on the netbeans site that shows how to generate the
interfaces at http://mdr.netbeans.org/example.html.

Regards
Ludger
