Deploy and Run in NetweaverDeveloperStudio

Hi all,

When i say Deploy and Run the application in NetweaverDeveloperStudio.I am getting an error says

Deployment exception : Cannot determine sdm host (is empty). Please configure your engine/sdm correctly !

I checked in my PC by giving command telnet<host><port> its working but coming to NWDS its not working.

Can anyone suggest me in this.

thanks,
