Hi Thufir,
Zachary allready wrote a lot about possible problems with different
scopes in jsp, passing the ResultSet this way shouldn't bring up any
problem IMHO - as long as the instance is destroyed after the page has
rendered (don't know exactly if the reference to a resultset in your
instance blocks your database connection as long as the resultset can't
get destroyed (but I assume this), so maybe you should consider
executing an explicit close() on the resultset). But I didn't understand
the first part of your mail:

I think that the problem with this class is that setColumnNames and
setData aren't really setting attributes. I suppose I should make
instance attributes like "header" and "data"?
You want to render a table, so you're creating rows for header an data
and adding them to the parent table. If you want to alter the table
after creation, you could additionally keep the TRs in a list as
attributes or something like this.
But in difference to swing (or something like this), you're just
generating HTML, sending it to the client and the server part is
finished. The client renders the html you created and maybe, there well
be a click on a link or a form will be submitted, so you're having a new
request, you don't get a gui event like in swing. To simulate this
behaviour over http, there are technologies like jsf (or some other
frameworks like http://wingsframework.org/ what is some more like swing).
Greetings,
Martin
