Servlet Code to Update records in SQL database using Tomcat server

Posted by TechBlogger on 12:34 PM

In this post we will illustrate how to Search and display information from database.
This post is continued from previous post have a look on how to do:

 1. Database settings and Insetion of data into SQL database.
2. Searching information from Database
3. Deleting informstion from database

Create a html form upinfo.html

<html>
<head>
<h1><u>student form</u></h1>
</head>
<body bgcolor="DarkSalmon">
<form name=Student method=POST action=http://localhost:8080/examples/servlet/upinfo>
<font face="Copperplate Gothic Bold">STUDENT NAME</font face>:<input type="text" name="t1" size="30"><p><br>
<font face="Copperplate Gothic Bold">ID</font face>:<input type="text" name="t2" size="30"><p><br>
<font face="Copperplate Gothic Bold">AGE</font face>:<input type="text" name="t3" size="30"><p><br>
<font face="Copperplate Gothic Bold">BRANCH</font face>:<input type="text" name="t4" size="30"><p><br>
<br>
<input type="submit" value="submit">
</form>
</body>
</html>


Now Create a up.java which has the actual logic for deleting information from database.

import java.io.*;
import java.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class upinfo extends HttpServlet
{
public void doPost(HttpServletRequest req,HttpServletResponse res)
throws ServletException,IOException
{
doGet(req,res);
}
public void doGet(HttpServletRequest req,HttpServletResponse res)
throws ServletException,IOException
{
PrintWriter out=res.getWriter();
res.setContentType("text/html");
String s1=req.getParameter("t1");
String s2=req.getParameter("t2");
String s3=req.getParameter("t3");
String s4=req.getParameter("t4");
out.println("<html><body><h1>............................servlet updating..........:):).......</h1></body></html>");
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con=DriverManager.getConnection("jdbc:odbc:student1","sa","sa");
out.println("<html><body><h4>connectiopn established........</h4></body></html>");
String query="update studentinfo set name1='"+s1+"',age='"+s3+"',branch='"+s4+"'where id1='"+s2+"'";
out.println("<html><body><h3>updating from database.......</h3></body></html>");
Statement stmt=con.createStatement();
out.println("<h2>:):):)</h2>");
ResultSet rs=stmt.executeQuery(query);
out.println("<html><body><h4>thank you for registrating.......</h4></body></html>");
con.close();
}
catch(Exception e)
{
System.out.println("Error in login:"+e);
}
}

Servlet code to insert data into MS SQL database using Tomcat Server

Posted by TechBlogger on 12:18 PM

Unlike JSP and PHP Servlet is also server side scripting language. Servlet is Java based, Here this post we are going to illustrate how to add, delete , update and Search data from a form interacting with SQL database.
For consideration we will need tomcat server installed running on the system by default at port 8080 and sql database running on the system.

STEP 1:

Create database in Microsoft sql Query analyser .
Create table with 4 fields viz StudentName , ID , Age and Branch.
->Keep ID as  INT and set it as primary key
->keep StudentName as VARCHAR(100)
->keep age as INTEGER
->Keep Branch as VARCHAR(100)

STEP 2 :

This code is only for addition of information to the database

Create a html page as follows:

studentinfo.html

<html>
<head>
<h1><u>student form</u></h1>
</head>
<body bgcolor="DarkSalmon">
<form name=Student method=POST action=http://localhost:8080/examples/servlet/studentinfo>
<font face="Copperplate Gothic Bold">STUDENT NAME</font face>:<input type="text" name="t1" size="30"><p><br>
<font face="Copperplate Gothic Bold">ID</font face>:<input type="text" name="t2" size="30"><p><br>
<font face="Copperplate Gothic Bold">AGE</font face>:<input type="text" name="t3" size="30"><p><br>
<font face="Copperplate Gothic Bold">BRANCH</font face>:<input type="text" name="t4" size="30"><p><br>
<br>
<input type="submit" value="submit">
</form>
</body>
</html>

Now Create a page named studentinfo.java which has actual logic to interact with SQL database and insert information.

import java.io.*;
import java.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class studentinfo extends HttpServlet
{
public void doPost(HttpServletRequest req,HttpServletResponse res)
throws ServletException,IOException
{
doGet(req,res);
}
public void doGet(HttpServletRequest req,HttpServletResponse res)
throws ServletException,IOException
{
PrintWriter out=res.getWriter();
res.setContentType("text/html");
String s1=req.getParameter("t1");
String s2=req.getParameter("t2");
String s3=req.getParameter("t3");
String s4=req.getParameter("t4");
out.println("<html><body><h1>............................servlet running..........:):).......</h1></body></html>");
try
{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con=DriverManager.getConnection("jdbc:odbc:student1","sa","sa");
out.println("<html><body><h4>connectiopn established........</h4></body></html>");
String query="insert into studentinfo values('"+s1+"','"+s2+"','"+s3+"','"+s4+"')";
out.println("<html><body><h3>inserting into database.......</h3></body></html>");
Statement stmt=con.createStatement();
out.println("<h2>:):):)</h2>");
ResultSet rs=stmt.executeQuery(query);
out.println("<html><body><h4>thank you for registrating.......</h4></body></html>");
con.close();
}
catch(Exception e)
{
System.out.println("Error in login:"+e);
}
}
}
