how can make the option to send mail only to checked people with jsp or html?

fisrt, here are two pages

1) students table with checkbox option and 'writing mail' button on the bottom

2)your page changes to this page through the bottom button on the first page there are title and contents and 'sending mail' button on the bottom

I made students table with name, id, and email address. and put checkbox option on the left side so that I can pick whom I am going to send email to : if I chekced 2 of 5, then I just send to 2 students. So, I wonder how can I deliver these checked persons' in the first page information to second page so that I can send mail to them by clicking 'sending mail' button.

I used like this to make check box:

and then stuck with this problem, having no idea what can I do. what kind of option do I have to use to solve this problem in jsp or html?
