I doubt this will be enough, but I'll offer it up to get you started.
Suppose I have the following form-bean:
<form-beans>
<form-bean
name="itemDetailForm"
dynamic="true"
type="org.apache.struts.action.DynaActionForm">
<form-property name="view"
type="com.oreilly.struts.catalog.view.ItemView"/>
</form-bean>
...
</form-beans>
I have specified that the form will hold an object of type
"com.oreilly.struts.catalog.view.ItemView", using a name of "view".
Further supposed that I have a GetItemDetailAction that has this execute
method:
...
public ActionForward executeAction(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response,
UserContainer userContainer) throws
BaseException {
String itemId = request.getParameter( IConstants.ID_KEY );
ICatalogController catalogController =
userContainer.getCatalogController();
// Get a value object representing the item from the business tier
ItemView itemView = catalogController.getItemView(itemId);
// Set the ItemView into the Dynamic Action Form
((DynaActionForm)form).set("view", itemView);
// The parameter name 'view' is what is defined in the Dynamic form
// in struts-config. Maybe should use a constant there too?
// Return to the success resource for this action
return mapping.findForward(IConstants.SUCCESS_KEY);
}
Now, in the JSP page that the user is forwarded to, they can use all of the
Struts tags to get at the ItemView data inside of the dynamic form. I won't
show the JSP page, it's too long. Here's a couple of lines from it:
<bean:write name="itemDetailForm" property="view.name"/>
<html:link
page="/action/cart?method=addItem"
paramId="id"
paramName="itemDetailForm"
paramProperty="view.id"
paramId="id"
paramScope="request">
Notice that view.name would be translated into getView().getName() like a
standard ActionForm.
I hope this helps somewhat.
