import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class search extends HttpServlet {

	/**

	public void doPost(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
String username=request.getParameter("username");
java.sql.ResultSet rs=new DB().search(username);
