I tried via list server email address last week but apparently it does
not work!

Not when you dont have a Form for your Action, which in my case ;)
Maybe I do not understand the question; you are referring to a normale
Form-Action-JSP model. Maybe Brett is too!?

no need to put the form Bean using the request.setAttribute("beanname",
bean) . It is done by struts framework .
rest is fine . Use <html:form> tag in Jsp .

RE: How do you load information into a bean that your form uses before displaying it?

The pattern I use works as followed:
- create a Action which reads data from a database
- stuff all data in a bean and request.setAttribute("BeanName", bean);
- forward to your "view" jsp and reference your data as <bean:write
name="BeanName" property="field"/>
NOTE:
directly requesting the .jsp will give you an "cannot find bean BeanName"
exception. you may want to add a trap for that or simply moving the .jsp out
of a public folder (to WEB-INF/ for example)

Subject: How do you load information into a bean that your form uses

I have a struts <html:form> which uses a struts Form bean. I'd like to read
data from a database and use that data as the default data for the form.
What is the best way to do this?
Read the data and set the value parameter of the <html:text> <html:select>
and <html:checkbox> tags?
Load the data into a Form bean and use that bean for the form?
I'm not sure how to do either of these options or if there is a third better
way to do it?
Thanks,
Brad

Re: Getting session objects in an Action Form

You can access the session through the HttpServletRequest:
Object myObject = request.getSession().getAttribute("myKey");
