Write Program For Validating Username And Password
Question
Automatic Log-in
a. Implement a servlet that presents a new user with a form containing fields for entering a user name and password (the latter should use an appropriate type of input element). The form should also contain a checkbox, initially unchecked, labeled “Check to log in automatically in the future.” If the user checks the box and successfully logs in (that is, the username and password are both “CSisCoolStuff”), then the user name and password should be stored in two cookies (you may assume that cookies are enabled on the client). After successfully logging in, the user should see a page that says “Logged In Successfully.” An unsuccessful attempt to log in should return the user to a page with an error message followed by the original login form, with the checkbox checked if it was checked on the previous form and unchecked otherwise. On subsequent visits, the servlet should attempt to log the user in using cookie information, if available. If this fails, the user should see the original log-in form, without any error message. If it succeeds, the user should see a “Welcome Back” page. Set the cookies to expire after six months.
b. Extend the program in (a) so that if it tries to store the user name and password in cookies but fails, it will display a message on the “Logged In Successfully” page informing the user that cookies must be enabled in order to automatically log in.
Summary
The question belongs to Computer Science and it discusses about writing a program that validates a web-user by offering a checkbox with username and password. For successful login with the login Id and password, the program must show a window saying successfully logged in and with wrong login Id and password, a window should show an error message. This has been presented in the solution in detail. You can find the program attached along with the solution.

WHAT OUR STUDENTS SAY
I was not sure on how to go ahead with my peripheral vascular diseases when I came across TheReliableTutor’s cardiovascular assignment help section. I never knew that any website had such specialized department and I was extremely thrilled. The cardiovascular nursing care experts here are very wise and provided adequate solution to the assignment. Later on also, during my course I had great help from them.
Thirza Toes Student
The timely and professional manner in which my economics thesis writing expert interacted with me throughout the process really impressed me. The knowledge and research of the expert on the topic that I had selected was absolutely flawless and really in-depth. My professor was very happy with the proposal and the consequent thesis paper. Thank you HwA!
Graham Hailey Student
There are things I failed to get a grasp on in my classes and for that reasons assignments often looked much more challenging for me. However, luckily I came across HwA and from my BSc N course till the final year of my MSc N course I always take their help and get good results.

1. Process control assignments in chemical engineering were a very difficult challenge for me. I was totally unsure about the application of laplace transform and differential equation in chemistry. Then I came across HwA and their experts are truly knowledgeable. She helped me with my assignments and showed, actually how easy it is.
Laurie Bunting Student
I chose civil engineering for my graduate studies because I am fascinated with the concepts of municipal and urban engineering. Since it has been my area of interest from high school and I had done some research on the topic I thought the graduate program would be a breeze. But I was soon proved wrong and found myself struggling from the very first semester. At TheReliableTutor.com my online civil engineering assignment tutor helped walk me through the different concepts and with in-depth quality research that was missing from my work.

Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
