I had this exact problem. My solution was to create a managed bean in the application \
scope that implements the Map interface. You need to override the get method and in \
there I use reflection to find the constant field value. Then I store that in an \
actual HashMap (which is declared as final and static in the managed bean), so next \
time it just reads it off the HashMap. Eventually every constant accessed will be in \
the Map and reflection won't be used anymore. I wrote about this on my blog a while \
ago, http://rossner.wordpress.com/

Unfortunately anything on wordpress.com is blocked from my current location so I \
can't give you the permalink address but I think it's the second most recent post \
(haven't posted anything in a while...). I'm wondering if the spring thing works in a \
similar way.

If you use Spring, you can use a FieldRetrievingFactoryBean to expose 
your constants as beans.
