a basic question
Hi everybody!
I'm new in struts and i want to know if someone can help me what is the best form to update a form from a enterprise javabean...
this is the code suppossing that the actionForm's name is proyectosForm ...
public ActionForward edicion(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws IOException,ServletException {
String user = request.getSession(true).getAttribute("user"); //To recover the user attributte
ProyectosBean p = getProyectos("user"); //To get the EJB whit the value to edit
request.getSession(true).setAttribute("proyectosForm",p); //to put it the session scope
return mapping.findForward(target);
}
Is this sufficient or i need more?,
Thanks.

BeanUtils work fully with mapped form-beans.
To make it more simple, you can add
void populate(Map) and
Map describe()
methods to your beans and just use :
form.populate(businessBean.describe());
businessBean can use BeanUtil to describe or populate itself.

You shoul use a form-bean that will copy datas from business, allow user to edit, and copy back when save is needed.
Look at BeanUtils.copyProperties() to copy datas from and to business Beans. You can also create a Factory to make the
copy :
myFactory.getFormBean(businessBean);
myFactory.getBusinessBean(form);

You should not use your business data as formBeans for some reasons :
- business data will not have only String or boolean properties
- business data does not have to extend ActionForm
- validate() or reset() have no sense on business tier.
You shoul use a form-bean that will copy datas from business, allow user to edit, and copy back when save is needed.
Look at BeanUtils.copyProperties() to copy datas from and to business Beans. You can also create a Factory to make the
copy :
myFactory.getFormBean(businessBean);
myFactory.getBusinessBean(form);
