Hi,
Thanks .its working fine now.

To build a map, you must have all the components:
1. FeatureSource, references data
2. LayerDefinition, references a FeatureSource
3. MapDefinition, references multiple LayerDefinitions
4. WebLayout, references a MapDefinition

All these items must be in a repository (either Library or Session) 

I know the procedure to create it in mapguide maestro.


   1) Now my problem was  i want to create   ALL the above items
programmetically (my input is only a shape file)  byusing maestro dll.


If u know this plz help me

Regards,
Padmini.
