QUESTION:

Develop a web application using HTML &Servlets for the given scenario below: (Required database tables implementation must be done) Write a servlet that enables the user to change the password from an HTML form, as shown in Figure. Suppose that the user information is stored in a database table named Account with three columns: username, password, and name, where name is the real name of the user. The servlet performs the following tasks:

Verify that the username and old password are in the table. If not, report the error and redisplay the HTML form. Verify that the new password and the confirmed password are the same. If not, report this error and redisplay the HTML form. If the user information is entered correctly, update the password and report the status of the update to the user, as shown in Figure. AIM:

To develop a web application to change the password using database connectivity.

PROGRAM CODE:index.html<html><head><title>change password</title></head><body><form method="get" action="http://localhost:8080/ses32c/ses32c.jsp"><font face="Times New Roman" size="4"><h1 align="center">Proceed to change password</h1><pre><font face="Times New Roman" size="4">User Name: <input type="text" name="name" value="" /><br>Old Password: <input type="password" name="op" value="" /><br>New Password: <input type="password" name="np" value="" /><br>Confirm Password: <input type="password" name="cp" value="" /><br><input type="submit" value="Change" /> <input type="reset" value="reset" /><br></font></pre></form></body></html>

ses32c.jsp import java.sql.*;import java.sevlet.*;import java.httpservlet.*;public class demo{Public void doGet(HttpServletRequest req, HttpServletResponse res){Pw.printwriter();

String no=request.getParameter("name"); String no1=request.getParameter("op"); String no2=request.getParameter("np");R try{ Class.forName("org.apache.derby.jdbc.ClientDriver"); }catch(ClassNotFoundException ex) { out.println("Class not found"+ex);} try { Connection con=DriverManager.getConnection("jdbc:derby://localhost:1527/account","acc","acc"); //con.setAutoCommit(false); Statement st=con.createStatement(); String q="select * from account where name='"+no+"'"; ResultSet rs=st.executeQuery(q); rs.next(); if(rs.getString(2).equals(no1)) { rs.close(); q="update account set newpwd='"+no2+"' where name='"+no+"'"; st.executeUpdate(q); q="update account set oldpwd='"+no2+"' where name='"+no+"'"; st.executeUpdate(q); q="select * from account where name='"+no+"'"; rs=st.executeQuery(q); rs.next(); pw.print("<p align=\"center\"><font face=\"Times New Roman\" size=\"4\" color=\"violet\"><b>Password changed successfully</b></font></p>"); } else { out.print("invalid entry"); } } catch(SQLException e){ pw.println(e); e.getStackTrace() ; }

OUTPUT:

RESULT:Thus the JSP code to change the password using database connectivity is completed successfully and the output is verified.
