public class FortuneEmployee extends HttpServlet

{

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

{

ResultSet rs;

PrintWriter out=res.getWriter();

res.setContentType("text/html");

out.println("<html><body>");

try

{

EmployeeInfo info=new EmployeeInfo();

info.setid(Integer.parseInt(request.getParameter("Emp_id")));

Class.forName("oracle.jdbc.driver.OdbcDriver");

Connection con=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:xe"."system","abc123");

PreparedStatement ps=con.prepareStatement("Select * from employee where Emp_id=?");

rs=ps.executeQuery();

ps.setInt(1,info.getid());

out.println("table border=1 width=50% height=50%>");

out.println("<tr><th>Employee name</th><th>Employee age</th></tr>");

while(rs.next())

{

String name=rs.getString("Emp_name");

int age=rs.getInt("Emp_age");

out.println("<tr><td>" + name + "</td><td>" + age + " </td> </tr>");

}

out.println("</table>);

out.println("</html></body>");

con.close();

}

catch(Exception e)

{

out.println("error");

}

}

}

In the above program by using servlets in java i retrieved the information of an employee from employee table which is stored in oracle database and dispalyed employee information in the table format on the screen.
