Have you taken a look at the Struts logic tags?... ...more specifically the <logic:iterate> tag. Quite sure this will do the job.
As for "displaying first N of the collection", you can set "offset" and "length" attributes to the tag, and it will do just that. You can also use any form of a Collection, including a primitive Object[]. It will retrieve an Iterator from the collection, and go over that. So ArrayList will work as well as a Vector (albeit that _little_ bit faster). HashMaps and such will also work, but the offset and length will be useless. :) There's a lot of tags in the Struts booty. Take a read over them some time. They'll be the answer to most problems.
