jsp:usebean will search in scope or create bean and asing a script variable "person" > <logic:iterate id="person" name="persons"> logic:iterate implicitly create a script variable form id attriute. This is the reason you get "person is already defined". Just delete your <jsp:usebean>. I don't understand why you get this "cannot find bean person...", as <logic:iterate> put it in pageContext.
