First I have created the plug-in project using "plug-in from existing jar archive". and I added this plug-in in my eclipse rcp application through "plug-in.xml --> dependencies --> required plugins --> add .
When i doing so and run the application, it not even recognise the eclipse core apis and it throws the error like:
