i am using jsp to create web site. How can i insert data into database but do not have text box in the web site. i want to have data automatically show in the database without having people key in data from web site. the purpose for doing this is i want to generate default answer for every member.

hmm how would the data go in the databbase? what type of database are you talking about? better yet, what is it that you are trying to do?

Ditto.. and also, when you insert data from a textbox into a database, do you put it into an intermediate variable first? If so, can you just substitute a value for that variable? Or can you use a < input type="hidden" name="name" value="value> for your purposes?

i want to generate answer for the user. every user will have different answer. their answer will be what is their lot no. i already generate question for them which is "what is my lot no?"
i attach part of my code. Every data in the code are fine except "answer" part because data that insert into database was wrong. data in database under "answer" field all has same data.
