The JSTL EL can reference javabean properties, maps, and collections.
That's it.  The JSTL specification describes this, although I wish it
had a concise statement to this effect.  You sort of have to figure this
out by deduction.

One curious strategy for accessing static variables would be to create
an object that gets associated with another class, which uses reflection
to load all the "static final" members into a map.  You could then
reference the map entries in the JSTL EL.  Obviously, you would have to
put that created object into one of the available scopes.
