attributes to look up an arbitrary ActionMessages saved under any key;
you can also specify a "property" attribute to filter the list to only
messages associated with a certain property.
As usual, see the docs for full details, but I prefer html:messages to
html:errors for this very reason.

Do you _really_ want to iterate over the validation errors, or do you
just want the output to be a bulleted list? If all you want is the
tags around your errors, this works:
ApplicationResources.properties:
errors.integer={0} must be an integer.
error.no.userId=User ID does not exist
error.no.email=No email address on file
errors.header=
errors.footer=
somePage.jsp:
(The 'error' style just sets the font and turns it red, it's not
required.)

markup in the .properties file doesn't seem "right" to me.

Re: Iterate over validation errors?
Here are a couple of old posts I saved that might help too:
At 5:10 PM -0500 11/8/04, Erik Weber wrote:
Here is a way to do it that works with 1.1:
Username:
Omitting the "name" attribute in this would have the same effect as
including it - it's the default. It's suggested that if you are storing
messages in your actions using "saveErrors" or "saveMessages" (or
dealing with validation errors, which are stored as if using
"saveErrors") then you shouldn't specify "name" literally; instead, you
can either rely on the default (to get errors) or use the "message"
attribute with a value of "true" (to get saveMessages messages) or
"false" (to get errors -- that is, the default behavior). This helps to
"encapsulate" the logic of how Struts handles those messages, and makes
your JSP a bit less verbose also.
Additionally, your code above assumes that the nature of the error
message is such that you know that the user should be shown the
"error.username.required" message -- it's probably more flexible to let
the validation/error handling framework create an ActionMessage object
with that key itself, and then you would use the messages object; this
way if any other error should come up (say you add a max-length
restriction, or forbidden characters), then you don't have to change
your JSP.
In another response I demonstrated how html:messages can be used to
achieve the same result you had above, plus this added flexibility I
mention.
Some people still like to use "html:errors", which predates
html:messages and which has a slightly different syntax for providing
any HTML which might "wrap" your messages. Personally, I prefer
html:messages.
None of this changed from Struts 1.1 to Struts 1.2.
Hope this helps,
Joe
Not sure if that tag has changed for 1.2.

I've never seen any automatic message placement. You can access
messages like this:
html:messages is effectively a combination logic/iterator tag. If there
are any "username" messages in the ActionMessages object saved as the
"errors" messages, the body of html:messages will be evaluated once for
each, with a scripting variable of type String defined with the name
specified in the "id" attribute. You can use c:out or bean:write to
display this value, wrapped with span, div, or other tags which format
your messages correctly.
I kind of think someone talked on the list once about making something
which rendered an HTML "label" tag and which was also "smart" about the
presence of errors. I like the idea of something like that in general,
but wonder if you'd be able to specify something suitably general for
inclusion in Struts. Seems like it might be better left for local
development.
Joe
But I think Niall recently mentioned some improvements in this area in
1.2.6 . . .

Re: Iterate over validation errors?
You could leave errors.header and errors.footer blank, and then wrap
your html:errors with the markup. Somewhere in the properties file
you're going to have to at least specify (markup) that you are using a
bulleted list if I'm not mistaken. There also is a way that you could
iterate over the individual error messages as you suggest. Then you
could have no markup in the properties file. See the docs for the
html:errors and html:messages tags.

RE: Iterate over validation errors?
There's one improvement on that method:
errors.prefix=
errors.suffix=
So you don't need to put the markup into each error definition in your
properties file.
If you don't want markup in it at all, you can do something like
