Hi Ravi,
are you using the developer edition or the vanilla solution? The developer edition comes with a frontend containing an eclipse and ADT installation. You connect to frontend and can start developing.
For both solutions you can also use a local frontend installation. You need a SAPGUI installation and eclipse with ADT. In SAPGUI you create a user specific system connection. Enter the backend IP displayed in the CAL as application server. The instance number is 00 and sytem id A4H. Finish the connection. You should be able to connect to the backend in the CAL.
Start Eclipse and create a new ABAP project. Select the connection you just created.
Have fun
Thea
