Servlet code for updating data in database

[J Das]

hi people.. i have a question related to an online bus ticket booking system.... Suppose a client gives his information in a form...(like his name, credit card number , address, email etc.) .. also he provides information on how many tickets he want.. Now suppose we have in our database table the total available tickets = 30, and if the customer buys 1 ticket, the database should be updated dynamically from the servlet , shouldn't it ?? I mean now the currently available tickets should be = 29 after posting the form .... What code is required to achieve the above... I am scratching my head... Please help me.....

I'll be moving this to the JDBC firm as this is a database question, not a servlet question.

And, in a properly structure web app, the servlet would delegate this task to a class in the Model layer.

Have you read about JDBC yet? If so, what part are you stuck on? Connecting to the database? Writing a SQL statement to decrement the count?
