* problem with JDBC

I have a problem with JDBC:
I write an applet including the JDBC code to connect to the pgsql server
to get data.
My applet runs fine everytime from the init() state.
But sometimes goes wrong if I press "Reload" on the browser which makes
my program runs again from the start() state.
The Statement gets the previous ResultSet to me when I
"executeQuery(SQLQuery)".
Is that possible that I get the previous ResultSet because I press the
"Reload" while the ResultSet is transferring to me ?
But the document says that the previous ResultSet will be close by the
Statement when that statement is re-executed .
Therefore, why do I get the previous ResultSet in the Statement ?

I don't know the answer, but I'll tell you that if you don't get an
answer here, there is a newsgroup at comp.lang.java.databases that should
be able to help you.

Applets are strange beasts at best.
When you press Reload, not everything is really reloaded. When I used to
write applets (a couple of years ago noe), I found that pressing reload
simply reloaded from cache, and not from the network. It might be the
case here that the browser is simply continuing the existing applet,
rather than stopping it and then reloading a fresh one.
As I said, it's been a couple of years since I wrote an applet, so I may
be wrong now.

You can do a "super reload" in Netscape/Linux by clicking and holding on
reload, pressing the shift key, releasing the reload button, releasing the
shift key. Note that this is slightly different from a "shift click",
which I think is how you do in on Windows.
You may also find that you need to update the timestamp on the page
itself, in addition to the class files for the reload to work.
