What kind of reply do you expect? You only posted some program, but did not post any relevant input data, so nobody can reproduce your error.

You can test with any sample xmi file. I installed everything that was told by all wrt to UMMF. I also insatlled patch in my system. After doing all the above when i tried to run it with a sample xmi file i got the mentioned error..You can just create any class diagram and test the code.. If i have given any wrong parameters please tell me.

I don't know anything about UMMF. I don't havew any XMI example file. I don't have any UML drawing program. I guess that most people here are the same.

If you don't tell us exactly what you did and make it easy for us to replicate your problem, you will have to work on your problem yourself. Asking repeatedly for answers without providing enough information, or waiting that we ask for more information instead of doing your work and providing enough information already, will not improve your chance of getting help.
