How can i open Keyboard viewer which is inbuilt in all Mac OS X from my application.

On 10.5 and earlier here's the path to it so just launch it like normal:
/System/Library/Components/KeyboardViewer.component/Contents/SharedSupport/KeyboardViewerServer.app
On 10.6 and later that doesn't work. You'll need this: http://github.com/nriley/keyboardViewer
