A page scope bean is valid in the page only. Why do you expect to access a
page scope bean from another page? Consider request or session scope. If I

I have my scope set at page and I input date from the screen and post it
tthe next page using
jsp:useBean id="b" scope="page" class="GrantBean">
<jsp:setProperty name="b" property="*"/>
</jsp:useBean>
in the next page toset values to the bean

How do you save and retrieve the bean? What scope you use?
