Hi Baljinder,
The best approach that I know of is to create an
Exception for each type of expected error, like a
duplicate key in a DAO.
Then create a message in a global message resource for
each full class name so that the key is unique.
Example,
java.lang.Exception=Something bad happened dude
Then for every action that throws an error like this
configure the input attribute of the <action> tag in
struts config.
Then your user gets the message on the page which
lanched the action.
In every action do a try { code } catch (YourException
e) { messages.add } and a,
if (!messages.isEmpty()) {
saveErrors(request, messages);
return mapping.getInputForward();
}
Of course <html:errors/> must be used in the input
jsp.
And then your users will understand better what is
going on.
Good question, other comments are welcome,
Phil
