More recent struts2 versions have more useful iterator use cases, so now you can just use begin, end, and step http://struts.apache.org/2.x/docs/iterator.html
If you're using 2.0 for some reason you can use an OGNL trick to get the result you're after: <http://www.opensymphony.com/ognl/html/LanguageGuide/coerceCollection.html> says "Members of java.lang.Number are "walked" by returning integers less than the given number starting with zero"
So if you have an OGNL expression %{#foo} that contains/results in the value 7, then the OGNL expression %{#foo.{#this}} will result in the list {0, 1, 2, 3, 4, 5, 6} over which you can iterate.
