RE: session form bean problem -- post again.
Thanks, David. Could you please give a simple example to explain how to
specify another bean?

If you want to display something form the session object stored with
Constants.USER_KEY in /search.jsp (your success forward), you don't need
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
taglibs.

Subject: session form bean problem -- post again.
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
validate=false
-
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.

RE: session form bean problem -- post again.
T.T.,
Before I give you an example, let me just yell read the manual at:
Struts Developer Guide - link HTML Taglib API Reference URL
http://struts.apache.org/userGuide/struts-html.html
Now, on to practical matters.
As you may know, traditionally, you have an html:form in your JSP like so:
html:form action=someaction /
html:text property=field1 /
html:text property=field2 /
/html:form
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:
bean:write name=user property=firstName /
html:text name=user property=firstName /
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.
Regards,
David
