How to store checkbox value into database?

I have a table which each row have a few checkbox and n开发者_Go百科ow i would like to do it if i have click on that checkbox it will update it inside the database. How can i code it using jsp?

First define a form in JSP which submits to a servlet.

<form action="servleturl" method="post>

Then place a checkbox in there with a name and value.

<input type="checkbox" name="foo" value="bar" />

Then create a servlet which listens on /servleturl and gets the parameter in doPost() method.

String foo = request.getParameter("foo");

It'll contain bar or null depending on checked state. Then you can do your DB thing.

fooDAO.save(someID, foo);

If that's also a problem already, then you need to learn JDBC and DAO. This is however unrelated to JSP/Servlets. Start with the JDBC tutorial.
