Hi !!!
I was working ok, with hibernate and mysql but yesterday I try to install the new mysql version (4.1.10) and receive the following error when I try to connect

Somewhere I red that was necessary to update the jdbc driver, so I updated it from version nro 2 to version nro 3.1.7 but still the error
Phpmyadmin works ok and mysql control center can connect ok too.
But when I try a telnet localhost:3306 I receive and error of connection filed
Anyway the mysql status thowme correct information, that it working ok!
Any idea ?
King regards
