The given code accepts username and password to check whether the user is valid or not. If the user is valid, whole record of that particular user will get retrieved from the database and displayed it on the welcome page. Apart from this if user is not registered, then he or she can register himself first and then login.

1)login.jsp:

<html>
<script>
function validate(){
var username=document.form.user.value;
var password=document.form.pass.value;
if(username==""){
 alert("Enter Username!");
  return false;
}
if(password==""){
 alert("Enter Password!");
  return false;
}
return true;
}
</script>
<form name="form" method="post" action="check.jsp" onsubmit="javascript:return validate();">
<table>
<tr><td>Username:</td><td><input type="text" name="user"></td></tr>
<tr><td>Password:</td><td><input type="password" name="pass"></td></tr>
<tr><td></td><td><input type="submit" value="Login"></td></tr>
<tr><td></td><td><a href="register.jsp">New User: Register Here</a></td></tr>
</table>
</form>
</html>

2)check.jsp:

<[email protected] import="java.sql.*"%>
<%
try{
String user=request.getParameter("user");
String pass=request.getParameter("pass");
 Class.forName("com.mysql.jdbc.Driver").newInstance();
    Connection con=DriverManager.getConnection("jdbc:mysql://localhost:3306/test","root","root");  
           Statement st=con.createStatement();
           ResultSet rs=st.executeQuery("select * from register where username='"+user+"' and password='"+pass+"'");
           int count=0;
           while(rs.next()){
           count++;
          }
          if(count>0){
           out.println("welcome "+user);
           %>
           <table>
            <tr><td>First Name:</td><td><input type="text" value="<%=rs.getString("firstname")%>"></td></tr>
            <tr><td>Last Name:</td><td><input type="text" value="<%=rs.getString("lastname")%>"></td></tr>
            <tr><td>User Name:</td><td><input type="text" value="<%=rs.getString("username")%>"></td></tr>
            <tr><td>Date Of Birth</td><td><input type="text" value="<%=rs.getString("dob")%>"></td></tr>
            <tr><td>Age:</td><td><input type="text" value="<%=rs.getInt("age")%>"></td></tr>
            <tr><td>Email</td><td><input type="text" value="<%=rs.getString("email")%>"></td></tr>
            <tr><td>Address:</td><td><input type="text" value="<%=rs.getString("address")%>"></td></tr>
            <tr><td>Country</td><td><input type="text" value="<%=rs.getString("country")%>"></td></tr>
            <tr><td>State:</td><td><input type="text" value="<%=rs.getString("state")%>"></td></tr>
            <tr><td>City</td><td><input type="text" value="<%=rs.getString("city")%>"></td></tr>
            <tr><td>Telephone No:</td><td><input type="text" value="<%=rs.getInt("telephone")%>"></td></tr>
            <tr><td>Mobile:</td><td><input type="text" value="<%=rs.getInt("mobile")%>"></td></tr>
           </table>
           <%
           }
          else{
           response.sendRedirect("login.jsp");
          }
        }
    catch(Exception e){
    System.out.println(e);
}
%>
