select w/Swing's JTable widget

Hi,
    I would first like to thank all developpers that are working on
PostgreSQL. It's an awesome piece of software.

Secondly, I've a simple question. I'm developping a small application in
Java and I use the Swing (JFC) widgets set. I have to do a select on a
table and put the result in a JTable object. My question is, how (in an
efficient manner) should I construct my JTable object since I do not know
in advance how many rows I'll have (available through my resultset).
Playing with Vector objects is annoying and with Object[]{[]} .. it's
pretty static :)

Thanks a lot,
        Ludovic

I second that.

The model side of it ? - then think again.
The component side of it ? - then the swing list is THE  place to look
for.

What's wrong with Vectors (or Collections) ?

I once played with Swing some time ago, with little success (it brought
the machine down). That was some time ago, so I'll be looking at swing
again fairly soon.

There is no way of knowing how many rows are in a ResultSet, without
reading in the entire set.

Also, I thought JTable could handle ResultSet's?
