I think there are some little things in that construct:
> > <j:set var="iterations" value="${3}">
Should be <j:set var="iterations" value="3"> because '3' is no variable.
(maybe ${3} also works, but that is a little bit of an overkill.)

this should be <j:while test="${iterations > 0}"> because the whole
test-expression must be included in {} and > is an xml-keyword.
I for myself would use
<j:forEach var="it" begin="1" end="3">
<j:set var="iterations" value="${4 - it}"/>
<log:info>${iterations}</log:info>
</j:forEach>
(forEach taken from jstl-doku but I think it's the same as in jelly!)
