I have tried
#foreach($i in [1..$n])
Where $n is set into the context as

context.put("$n", rs.getString("n"));

oops.  I should have caught it myself.

context.put("$n", rs.getInt("n"));  did the trick

Thanks for your insight.

as well Velocity 1.7 fails when it reaches the range variable in the
#foreach directive.

Is there a way to accomplish what I am trying to do, (a variable count
loop) in velocity?

The error is that you're not actually iterating over a range, but trying to iterate over a string.

#set($range = "[1..$n]") => $range is a String
#foreach($i in $range) => $range is still a String, it won't be replaced with [1..$n]

This should work:

#set($n = 2)
#foreach($i in [1..$n])

If you must define the range somewhere else as a string, you can use #evaluate to dynamically interpret the range, but that adds unneeded complexity.
