Hello..
I am a newbie to Struts. While reading the documentation, I gathered that
"ActionForm" objects can be used to move data back and forth between HTML
forms fields and ActionForm properties by using the formBeans.
With proper entries in struts-congif.xml, Struts framework automatically
creates the instance of "ActionForm" class and populates its properties
based on the HTTP Post Request parameters while submitting a HTML form. I
can see the form values in m y ActionForm and also in Action class.
However, how do I achieve the same thing backwards. I mean, if I retrieve or
generate some values in a Action class code, and populate these values in
the ActionForm by calling myForm.setXXX(), I don't see these values
appearing in the corresponding HTML form that gets forwarded by my Action.
here is the part of my struts-config.xml
<form-bean name="personnelForm"
type="blankApp.PersonnelForm"/>
<action path="/getpersonnel"
type="blankApp.PersonnelAction"
name="personnelForm"
scope="request"
input="/personnel.jsp" >
<forward name="success" path="/personnel.jsp" />
</action>
Here is the code from PersonnelAction.java:
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception
{
PersonnelForm fForm = (PersonnelForm)form;
fForm.setRank("RANK");
fForm.setPaygrade("PG");
System.out.println(fForm.getRank());
System.out.println(fForm.getPaygrade());
}
Where rank, paygrade are properties of PersonnelForm.java and also defined
as html:text in personnel.jsp.
When I execute the /getpersonnel.do action, I see my code getting executed
in PersonnelAction.java, but muy text fields in HTML form generated by
personnel.jsp are blank. I expected it to display the data from
PersonnelForm properties.
What am I doing wrong?
thanks
