communication between control layer & factory/model
I've been happy until now passing objects backwards and forwards between
my actions and my factories, and occasionally a int with the number of
updates or deletes done, for example, to include in the status messages
I show to the user, and throwing exceptions for anything else.
However I've just programmed a page with nested beans and the factory
does the whole process in one transaction, covering three different
operations which I would like to give three different status messages for.
In brief it is the realm user admin page and the list of nested beans
are users - on which the admin op can update the email address, reset
the password or delete the user entirely.
I want to tell the admin how many of each operation were done. I could
either pass back an ActionMessages, but I don't want to mix struts into
my factory layer, or I could pass back a string with different parts:
# of email updates
# of password resets
# of deletions
Which is not exactly elegant, since I have to tokenize it.
Anybody got any better solutions?
Adam

Re: Hi Ted, where is scaffold.ExistsAttributeAction??

The source is under the Struts contrib folders.
Yes, the scaffold package has been stable for some time now.
The next thing might be a similar set of classes that work with the
Commons Chain package. It would be the same strategy, though: use the
Action as an adapter to call reusable business layer classes.

Hi Ted,
I'm studying your artimus_1_1 codes.
I'm confused by some scaffold classes, such as org.apache.struts.scaffold.ExistsAttributeAction.
I cannot find it's source code, compiled class file and it's documentation anywhere. There are some other classes like this one.
I noticed that scaffold's last update was about one year ago.
Is scaffold still being working on?
Sincerely,
Bruce.

One of the tasks along the 1.2 path is to make Struts itself use this
package, in the same way that we use the beanutils and digester packages
that were originally in org.apache.struts.util. Among other things,
that means we all benefit when additional Resources implementations are
created for different data sources (like one to read resources from a
database).

That seems to fit the spec perfectly!

How about the Commons MessageResources?
http://jakarta.apache.org/commons/sandbox/resources/index.html
We ported the message collection over there for precisely this reason. :)
HTH, Ted.

Yes, looked at that, seems the most elegant solution, at least until I
get my hands on commons messages - I did something like this:
HashMap results = factory.updateAll(conn, users);
msg = new ActionMessage("userAdmin.status.savedEmail",
"" + results.get(factory.EMAIL_RESULTS_KEY),
new java.util.Date());
messages.add(ActionMessages.GLOBAL_MESSAGE, msg);
msg = new ActionMessage("userAdmin.status.resetPassword",
"" + results.get(factory.PASSWORD_RESULTS_KEY),
new java.util.Date());
messages.add(ActionMessages.GLOBAL_MESSAGE, msg);

can't you pass a HashMap back?
