Hi everyone,
Recently we have upgraded postgres driver jdbc4 for 8.3. After that
while executing rst.first(), it raise the exception.
The statment was created correctly as
dbconnection..createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);

org.postgresql.util.PSQLException: Operation requires a scrollable
ResultSet, but this ResultSet is FORWARD_ONLY.

Pleas help is solving this...

I guess there are two important questions:

1) do you want a forward only result set?

2) if yes, then cant you just remove .first()?

Its ok not to use first, right:

q.open();
while (! q.eof())
{
do something;
q.next();
}
