It looks right, but I think the FeatureName should be:
SHP_Schema:india_st
(I have not used the SHP provider though, so I may be wrong).
Try to see if the error log has any messages.
C:\Program Files\MapGuideOpenSource2.0\Server\Logs\error.log
For (1), you can use any folder you like, as long as the web app has
write access,
and MapGuide has read access. I recommend using a folder that is only
used for this purpose.
For step (9), did you remember to set the layer visible?
Regarding the %MG_DATA_FILE_PATH%:
When saving a FeatureSource with Studio or Maestro, the SHP file
can be uploaded to MapGuide (called "Managed" in Maestro).
Files are uploaded with the call SETRESOURCEDATA.
These files will be stored in a folder inside the Repository folders, eg:
C:\Program
Files\MapGuideOpenSource2.0\Server\Repositories\Library\DataFiles\8b16416a-ffff-ffff-8000-02004c4f4f50\shape-file.shp
The number/character part is generated by MapGuide, and is not
accessible, so
you cannot guess/predict what the folder name is.
To use files that are stored in this folder, the FeatureSource has the
path %MG_DATA_FILE_PATH%,
which is then substituted to the correct folder name, when the provider
attempts to open a connection.
This ensures that if you move or copy a FeatureSource (even with a MGP
file), the path will be correctly
substituted.
You can also use this method if you call SETRESOURCEDATA after step 4,
to upload the file.
(Remember to set the path in step 3 to %MG_DATA_FILE_PATH%).
If you only need to use the SHP file in the current session, this has
the effect that
when the session expires, the file will be deleted automatically
together with the FeatureSource.
(If you store the FeatureSource in the Session:// repo).
