JavaMail?

I have a java web application and I want to do something basic but I am not sure what is the most simplistic way of doing it.

When a certain field in a table is updated, I want an email to be sent indicating the changes that have been made. The mail recipient will not always be the same. Is this possible? I've been reading about JavaMail but I am not sure what that is all about.

I appreciate any comments you may have. thanks!
