Hello, for those who continue to have this problem as I want to say solve, maybe it's useful for someone else.
My problem was the connector used, which was not correct, if you open the *.jar contains classes you will see that the original jar contains very few classes, what I did was download another connector and ready.
I leave the link where to download it:
