Tag support for:

[Casazza, Robert]

Maybe this is more related to Struts but I'm
curious as to whether Jakarta Tags allow:

[1] looping, in particular to be able to dynamically
        populate a table based on a collection of
        objects with attributes

[2] What general ways are there to populate tables
        with exactly X columns?

[3] Are there currently tags which look like checkboxes
        or radio buttons but which force a refresh to
        allow the current page to dynamically change
        based on the choices made?

Thanks.
