Hi Wasim Ahmed
Actually you don't need buy any books. There are a lot of resources on the web and on this forum.
What you actually need is to read: (all can be downloaded)
1)
Servlet Spec,
JSP Spec;
2) servlet/jsp APIs;
3) Core Servlets and Jave Server Pages by Marty Hall (could be downloaded
www.coreservlets.com) 4) Some books regarding
J2EE design models downloadable at
www.theserverside.com Of course if you have extra money or your company is gonna pay it for you, it is always good to have some reference books.
