ActionForm has the setter and getter methods for name, age and description.
Action:
public final class QueryParamsAction extends Action {
public ActionForward execute(ActionMapping mapping,
ActionForm form1,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
QueryParamsForm form = (QueryParamsForm)form1;
//String name = (String)
PropertyUtils.getSimpleProperty(form, "name");
String name = (String) request.getParameter("name");
//String age = (String)
PropertyUtils.getSimpleProperty(form, "age");
String age = (String) request.getParameter("age");
String description = (String)
PropertyUtils.getSimpleProperty(form,
"description");
out.println(name);
out.println(age);
out.println(description);
return (mapping.findForward("nextPage"));
}
My initial query string is:
http://localhost:8080/vijay/QueryParams.do?name=vijay&age=26
This instantiates the ActionForm, sets age and name, comes to teh Action,
print age and name correctly, prints description as null(as expected), goes
to "nextPage" whcih is QueryParams.jsp. In QueryParams.jsp, I print name,
age and assign a textbox for the atribute 'description' which when submitted
should set description in the ActionForm. It does so. When it comes back to
Action, description gets printed but name and age are now null.
> It should work the way you want (session scoped forms retain
> their values.)
