which proved to be an invaluable aid in the best practices of how to create a Struts-based wab-application.
I also found this site which seemed to give me all the answers I needed or so I thought: http://www.reumann.net/struts/lesson2/step9.do
So, I have a link from a JSP menu that looks like: http://www.mydomain.net/update_address.do
The struts-config.xml has the following declared:
In the form-bean definitions I have:
<form-bean name="memberAddressForm" type="com.tjh.csaa.beans.MemberAddressForm"/>
In the Action Mappings I have: <action path="/address_update" type="com.tjh.csaa.beans.MemberAddressAction" name="MemberAddressForm" scope="request" validate="false"> <forward name="choice" path="/membership/membership_choice.jsp"/> <forward name="success" path="/membership/membership_address.jsp" /> </action>
So, the idea is like the example, that is I call the Action (MemberAddressAction) which is going to get my "member" (MemberDTO) from the session (because the user has previously logged-in) and the MemberDTO is now in session. So, MemberAddressAction gets this "member" and uses the "populate" method I wrote to transfer the data from this "member" into the Form-Bean (MemberAddressForm).
Here is some of the code from the MemberAddressAction:
HttpSession session = request.getSession();
MemberDTO member = (MemberDTO)session.getAttribute("member");
if( member == null)
{
System.out.println("user has not signed in");
return (mapping.findForward("choice"));
}
else
{
MemberAddressForm memberForm = (MemberAddressForm)form;
copyBeanToForm(member,memberForm);
}
return (mapping.findForward("success"));I can vouch for sure that the "member" (MemberDTO) does exist in session correctly ... however, the form does not get created and as a result is null. So, question is WHY?
Why does this code not work and how can I correct it? MemberAddressForm memberForm = (MemberAddressForm) form;
Thanks again for any help.

Thanks for the info.
"membership_address.do" is the Action from the JSP page when I do my submit. If I call the this Action with validate=true, then it's going to call the FormBean Validate method first, and if anything is required, then it would get errors and return to the calling page with a bunch of error codes even though the user wasn't there the first time. I've seen other people ask that question before.
The Action you suggest I call, is this a new Action altogether with no validation? This action could either get data from the database, or if that is already done, then I could just take the data from the MemberDTO and put that into the formbean as you suggest, then I would automatically forward to the Membership_Address.jsp page. Is that correct, or do you mean go to the same Action as when I do a submit.
So, I won't be a bother to the list, can you re-direct me to the struts-example web-app? Can I download that app from the Struts web-site directly?
Thanks again for the help.

So, the way I started to handle this is call the JSP page directly with the form. I got the 'member' object from session and I populated the value field as follows: <html:text property="address1" value="${member.address1}"/> Would this be appropriate? It works except for my checkboxes.
No. Set those values in the Action code, before forwarding to the JSP.
The struts-example webapp shows how to do this-- look for the calls to
BeanUtils.copyProperties(...) that copy the values back and forth from the
DTO to the form bean.
Don't forget to write a reset method to handle those checkboxes.
