Write a servlet which accepts product details from html form and stores the product details into database?

Product database:
create table Product
(
pid number (4),
pname varchar2 (15),
price number (6, 2)
);

web.xml:
<web-app>
<servlet>
<servlet-name>abc</servlet-name>
<servlet-class>DatabaServ</servlet-class>
</servlet>

<servlet-mapping>

<servlet-name>abc</servlet-name>

<url-pattern>/getdata</url-pattern>

</servlet-mapping>

</web-app>

DarabaServ.java:

import javax.servlet.*;

import javax.servlet.http.*;

import java.io.*;

import java.sql.*;

public class DatabaServ extends HttpServlet {

 public void doGet(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException {

  res.setContentType("text/html");

  PrintWriter pw = res.getWriter();

  String pid1 = req.getParameter("prodata_pid");

  String pname = req.getParameter("prodata_pname");

  String price1 = req.getParameter("prodata_price");

  int pid = Integer.parseInt(pid1);

  float price = Float.parseFloat(price1);

  try {

   DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());

   Connection con = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:

    Hanuman ","

    scott ","

    tiger ");

    PreparedStatement ps = con.prepareStatement("insert into Product values (?,?,?)"); ps.setInt(1, pid); ps.setString(2, pname); ps.setFloat(3, price); int i = ps.executeUpdate(); pw.println("<h4>" + i + " ROWS INSERTED..."); con.close();

   } catch (Exception e) {

    res.sendError(503, "PROBLEM IN DATABASE...");

   }

  }

  public void doPost(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException {

   doGet(req, res);

  }

 }
