Re: Test whether an application resource is empty
Doh, I'm an idiot! :-( What I suggested is like trying to call getFoo()
on the resource bundle bean, where 'Foo' is what ever
<%=directionToUserKey.toString()%> evaluates to. Clearly not what's
needed. The following works for me:
using Struts bean/logic
Just replace 'errors.cancel' with '<%=directionToUserKey.toString()%>'
and you should be set.
Sorry for the confusion,

did wrong.

You want to use the name of the attribute the resource bundle is stored
under, not the name of the properties file. You're not specifying it in
your Struts config so you want the following:

Thanks Laurie,
I tried to set it up this way, but wasn't able to make it work. My
struts-config file defines the message-resources parameter like so:
So I tried putting that in, and also tried some variants like
org.apache.struts.ApplicationResources and
org.apache.struts.util.MessageResources in code like this:
key="<%=directionToUserKey.toString()%>"/>
But it always returned false, even if there was a value for the key,
so I apparently set up something wrong.
I did get it working using the alternate path, however -- I set up a
new tile in the tiles-defs file which was defined as a zero-length
file in the default case and a small JSP for those cases where I had
directions.
The calling JSP looks like this:
And the inserted tile (when I insert a non-zero-length file) looks
like
this:
<%
String directionsKey = (String)
request.getAttribute("directionToUserKey");
%>
That is working ok, though of course I don't have the flexibility of
having a value for some locales and no value for other locales. That's
not terribly important.
By the way, just for my own learning: I initially tried to put the
attribute in page scope, but I kept getting a null value: is page
scope specific to a particular JSP (I would have thought that was tile
scope...), or should it be available throughout the sub-elements of a
given page? It works when I use request scope instead, but is that
what is required here?
Thanks again for everyone's help!

Hi Wendy,
Thank you very much for your reply.
Yes, I also thought that I could test the key, then check to see if
the value was empty. But just how to do it is eluding me. I think part
of the problem might be this:
USAGE NOTE - If you use another tag to create the body content (e.g.
bean:write), that tag must return a non-empty String. An empty String
equates to an empty body or a null String, and a new scripting
variable cannot be defined as null. Your bean must return a non-empty
String, or the define tag must be wrapped within a logic tag to test
for an empty or null value.
(from the Struts User Guide for bean:define at
http://struts.apache.org/userGuide/struts-bean.html#define).
I'm trying to do something like
But it's failing (I think) because the bean:message returns an empty
String. I would wrap it in a logic tag as suggested, but if I could do
that, I'd just use the same logic for my logic:notEmpty tag instead.
So finding a way to take that value and assign that to a variable
which I can then test to see whether or not it's empty is what I'm
trying to do.
It was not my idea to add all of these empty i18n values: the i18n
team did it. If I can't find a way to make this idea work, that's my
alternate path. If that's the road I need to take, I can do it -- I
was just hopeful I could do this a little more elegantly.
Thanks for your input. Any further ideas?
Chris

RE: My IncludeAction-where to forward
Tony,
I suggest checking out a tiles Controller. It could create the menus for
you in a tile-based page WITHOUT needing to call multiple actions. Details
on this can be found in Cedric Dumoulin's Tiles Advanced Features PDF.
Link: http://www.lifl.fr/~dumoulin/tiles/ with an instructional PDF in the
"Welcome" section listed as "Learn Tiles Advanced Features".
Struts-menu might fit but it depends on where and when you want to
instantiate your two menus.
Why do I recommend avoiding an Action calling another Action? Because it
requires the whole request chain to be processed again - request parameters
and all. With a tiles action, you can have it in your template or only in
select pages, depending on your requirement, i.e. a member's menu that might
only be on member pages or a generic menu for all pages. That is left up to
you.
Again, this is just one of many opinions which might guide you on your way
to finding a solution that fits your situation and your coding style.
Regards,
David

RE: display the form values from view page
I would advise you read the sections
http://struts.apache.org/userGuide/introduction.html that explain how an
ActionForm works and how you get/set the form properties.
You need an ActionForm linked to your Action and struts will scrape the
properties from your page into the form and you just manage the form.

If you use Hibernate as your DAO layer, you could enable caching so DisplayTag won't hit the database every time, assuming you have the memory footprint to support that caching.
