I had a similar problem last week, which turned out to be caused by not calling the next() method on my ResultSet object. Remember a ResultSet defaults to cursor on line "0" so you have to call next() (or first() or absolute(1) or similar) to get to a result at all.

If that doesn't help, please post some more code.

Or tell us what the error is. Details are always helpful, whereas vague statements like "I got an error" are not.
