Well the parameters are only submitted from add1.jsp to add2.jsp.
They are not present when you submit add2.jsp (you have no inputs on the form on add2.jsp)

Solutions
1 - Make country a Session scoped bean. That means it will retain values between requests
2 - Put hidden fields on add2.jsp so that the parameters will resubmit themselves

ie

What you need is a good book or a nice tutorial of Servet and JSP.
