Ben, I am using a checkbox. What I am planning to do is allow the user to check/select items/checkboxes on the book display page and check/select the books he wants to delete from Book store. On submitting the form, I want to capture the set/list of checked choices so that I can take it as a array and pass it to my deleteBooks() method in my Action class. Please let me know if I was not clear and I could append my sample code snippets. I appreciate your swift replies

You're using a String[] as the form property, right?
