Okay, that looks like informix doesn't have a scrollable cursor. You
need to call setForwardOnly(true); before calling first(); (maybe before
exec() too, but try each and see how it goes. ).
Hope this helps.
Btw, in 4.6, this will be fixed to determine automatically that it's a
forward only dataset, and sets that parameter accordingly, but before
then, you have to set it yourself.
