This video will see how to implement login module in servlet and JSP. We have always seen the theory of this, right? So, what we need is a login page called login.jsp. We have a welcome.jsp and videos.jsp for JSP files. If I go to login.jsp, it should give me two text fields where I will enter my credentials: username and password. If I click the button and the username and password are correct, it should call the page welcome.jsp, which will welcome the user and print "Welcome username". It will also provide a button or link for the videos page. Once you click on the videos link, it will take you to the videos.jsp page where it will show some videos.

This page will display "This is Snowie ready from telesco telesco Lovings." This page should be open to everyone, without any restrictions. If I go to the login page, login.jsp and aboutus.jsp are unsecured pages. Meanwhile, welcome.jsp and videos.jsp are secured pages. Let's add a login button or a form to the login.jsp page. We will set the form action to call a servlet named login with the method as GET. We need a username field and a password field. Next, we require a button with the type "submit" and the value should be "Login". Once the user clicks on the login button, it will call the login.java servlet. Let's create the servlet. In the login servlet, we will fetch the details of the username and password from the request parameters. We will store them in string variables named "uname" and "pass". To verify the username and password, we can fetch data...
