Re-read the API description of this tag and the "collection" attribute:
"A runtime expression that evaluates to a collection (conforming to the
requirements listed above) to be iterated over."
You've given it a string, "rows", and not a collection. This is a
situation where using Struts-EL is convenient. You'd just replace
"rows" with "${rows}".
