Operation not allowed after ResultSet closed?

It's hard to be sure just from the code you've posted, but I suspect that the ResultSet is inadvertently getting closed (or stm is getting reused) inside the body of the while loop . This would trigger the exception at the start of the following iteration.

IMHO, you should do everything you need with your ResultSet before you close your connection.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
