If I substitute the following line instead it works fine.
<c:set var="emailNotifications" value="${EMAIL_NOTIFICATIONS}"></c:set>This line of code ...
<c:out value="${Constants.EMAIL_NOTIFICATIONS}"/>Outputs EMAIL_NOTIFICATIONS on the screen.
I think this is starting to look like it just isn't going to work, I don't think that jstl is too smart about dynamic
variables like this. I tried the other suggestion as well (
c:set var="const" value="${scope['Constants']}"/>
<c:set var="emailNotifications" value="${const['EMAIL_NOTIFICATIONS']}"/>
)But it didn't work either, this is starting to look as though it will be so convoluted that I might as well not be trying to use constants anyhow as I will have to look up the file anyway I might as well just use string literals.
Cause it isn't scriptlet I wont get auto-completion anyhow. I'm going to try the suggestion from Rick Reumann and then I'm gonna throw my computer out the window.

Just as an addition I can do this

And it works fine, but really what I am trying to get here is the value of using Constants in both my Actions and my ( JSTL based ) jsp's.
Perhaps this is just something that never occured to the writers of the JSTL spec ?

Ok, tearing my hair out right now and extremely confused.
If you look at the Java Technology Forums you will see a rather nice little pattern that someone called evnafets has created, it allows you to use a single Constants class both in your Actions and in your JSP pages ...
It uses reflection to add it's static final members to a map which can
then be accessed by JSTL lik
