Application resources and java
I have an application where a user logs in and what is presented to
them depends on what organization they belong to.
Things like the web page title, labels, images, etc. are different for
different organizations.
I'm thinking that I'd like to create application resources from the
login action that can be referenced with the bean:message tag. This
way, the key is always something like myapp.page.title rather than
having to use logic: tags or jsp to determine the appropriate
resource.
My questions are:
* Is the the appropriate way to do this sort of thing?
* Irrespective of the answer to the above, can one create / modify
application resources from java? (Like in an action?)
Thanks,
/greg

Interesting approach. We are facing the same challenge and fast. We are
basically are creating a shopping mall where each store has it's own look
but the same basic functioning under the hood. We have opted to pursue
moving the "static text" attributes out of the application.resource files
and put them into an application scope prop object bean. The prop object is
basically a n-level nested hashtable. This allows us to strip the hardcoding
out of the jsp so when you retrieve a "static text" attribute for a certain
user you could use:
Title = getprop(dept, title)
Gets the String value back of: HUMAN RESOURCES
Img src=getprop(dept, banner)
Gets the string value back: http://webserver/images/banner1.jpg
Since the prop object is loaded up once when the application starts and
doesn't care how the data is structured you can get pretty intense on what
you store in there as long as the application developer knows the key to get
the value of the property they want out. In our environment, we are going to
initially load from a database table (basically: ID, PARENT_ID, VALUE) and
if there is an edit we update the database directly and bounce the
application or we'll build an admin interface to the app that updates the
database and reloads the whole prop object (or subtree) that way we don't
have to redeploy the app to edit 'static text' or change an image name. This
will allow us to push some of the 'look and feel' customization out to the
client in the future if we want.
We're going to give it a try and see what happens.

I wouldn't create resources in an Action (I don't even know how), but
you can access them in an Action. Try this (based on a thread a couple
of months ago):
=========================
#in application.resources (or wherever you store your messages)
label1.condition1=SOME VALUE label1.condition2=SOME OTHER VALUE
=========================
//in your Action
MessageResources messages = getResources(request);
if (condition == condition1) {
form.setLabel1(messages.getMessage("label1.condition1");
} else if (condition == condition2) {
form.setLabel1(messages.getMessage("label1.condition2");
}
//etc, etc
The idea is
