Thanks again, David.

As you may know, traditionally, you have an html:form in your JSP like so:
If you saved a bean named "user" in request or session scope, you can access
its property "firstName" from any JSP with many of the bean/html taglib
commands such as:
Using the above, I've done the unthinkable. I have created a page that
has the html:form tag, then includes different "center" (I use tiles to do
this) JSP pages based on a Tiles controller. Then, each page uses the
html:text with name="anyScopedBeanName" to show particular fields from ANY
of the stored beans I choose to show. It works well with multi-page
validation schemes.

Thanks, David. Could you please give a simple example to explain how to
"specify another bean"?

to copy the values in your Action's execute() method. Just specify another
bean (in any scope) with the 'name="User"' attribute/value pair. Of course,
you'll have to change "User" to the actual string defined by
"Constants.USER_KEY". This works for many tags in the "bean" and "html"

Happy new year!
Since I posted this problem before Christmas and didn't get answer, I post
it again.
. I have such action mapping:
type="myClasses.PopulateAction"
name="SearchForm"
scope="request"

The code in the "PopulateAction" class is:
---
public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
HttpSession session = request.getSession();
User user = (User)
session.getAttribute(Constants.USER_KEY);
SearchForm searchForm=(SearchForm) form;
searchForm.setZipcode(user.getZipcode());
searchForm.setCity(user.getCity());
searchForm.setState(user.getState());
searchForm.setCountry(user.getCountry());
return (mapping.findForward("success"));
}

I want to populate "SearchForm" with some existed values(stored in
session) before showing "search.jsp". This work is done in "execute" method
of "PopulateAction".
It works well when I use the mapping code shown above. But when I take
out the line -- scope="request", that is, I want this form bean to be a
session bean. Then the values were not set. They are just the initial
values of the form bean.
It seems a new form bean object was created after "execute" method of
"PopulateAction". Or , "execute" method of "PopulateAction" was not
executed.
Any idea anyone?
Thanks in advance.
