LogoutAction Code :

public class LogoutAction  extends Action{
    public ActionForward execute(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response) {
        // To redirect to the Login page
        return mapping.findForward("success");
    }
}

Struts-config.xml part 

 <action path="/logout" type="com.dna.nsm.sim.action.LogoutAction" >
            <forward name="success" path="/tiles/login/body.jsp" />
 </action>

Suggestions please.

Check your imports and make sure you're extending the right Action class.
