Welcome to JavaRanch

THen,only we can help you

well i have made 2 JSP
one is a simple login.jsp which contains two text inputs and a submit with the form action to a java servelet

and a register page with all fields required for a ticket booking system like name address etc.. and most important the desired username and password confirm password..

what i want to do is to save this desired user in a string login_id array dynamically plus checking that if the id already exists !!

and the password in a different string login_pass... with one user's id and password at same position of the array like login_id[1] and login_pass[1]

if you wanti can post the servelt code i could think off please help m just a beginner !!

Here I could think of this naive code
I seriously need some professional help :P :P

appreciate if you could post your JSPs also.
Do you have only Servlet (login) in your application ?

~ abhay

are you making this login and registration system just to gain hand on knowledge on Servlets ?

Saving login id and passwords in String object will not have any retentivity. As soon as web conainer is restarted, all login id and passwords will be lost

~ abhay

ya i know every thing will be lost i am just making it to show that the thing works... because i have to show it on different computers
plus if i have to use database it'll increase the complexity of the program !!
but no problem if you can post a easier database code

the jsp is very simple one just a file with three inputs desired login id and password

PLEASE HELP !

If you know I/O, you can always save it to a file...

yes i thought of that option but that's the problem of being new to the language...
i don't know how to do it !!

i will appretiate if you could post the i\o code !!

But then, what would you learn? If you want code snippets, google it? You should really make it yourself, that's how you learn.

I find it strange to start developing Servlets and JSP's without a minimal understanding of Java SE API's...

ya i know but the point is
right now my priority is to make this website because i've been given this project and will be graded for it.

i tried to google the code but it was difficult and as you saw above i tried to make the code too so i was seeking a simple or atleast understandable code.

that's why i came for help here.
that's why this forum was built no ??
