Hi David,
Thanks again for the reply. I'm comparing MVC frameworks right now, and
wondering if struts2 has a similar feature to JSF. In JSF, an action can
look like this:
public class MyAction {
public String deleteUser() {
// Here I can inject errors for display on the JSP by writing:
FacesContext.getCurrentInstance().addMessage("userNameField", "Sorry,
that username is unknown");
return "input";
}
}
Notice MyAction inherits no JSF-specific interfaces and extends no
JSF-specific classes, which is I find very desirable.
Just wondering if struts2 has a way to decouple actions in this manner.
Spring-MVC does not and, of course, struts1 does not.
Thank you.

If you want the framework to recognize those errors, be able to use them
in
tags, etc. or make decisions based on their presence (or not), use the
validation framework (which expects to be able to add messages based on
the
ValidationAware interface) then yes.
If you want to create your own framework for handling errors then you can
do
whatever you want.
