Section : The Servlet’s Environment (1 of 1 )
1. In the ExoticaTravels Web application, a user has to make multiple selections, such as destinations, hotels, and travel tickets, to perform online booking. Therefore, you need to enable the Web application to track all these user activities across various Web pages. For this, you need to design multiple Web pages, which will allow the user to select various options, such as destination, hotel, and cab service. When the Tour Package Bookings link is clicked, the destination Web page similar to the following figure should be displayed.
