That driver was not tested with server version 4.0 (nor 4.1 nor 5.0) an is not likely to work with any server version for which lifecycle support ended . MySQL Sever 4.0 is out of support maybe for 7 or 8 years something like that.
Thank you for commenting. Yes I had MSQL Server 4.0 running for at least 12 yrs on an XP-machine, and few years before that on a Window 2000. I will download a newer version to continue development on my application. I have a question about the MariaDB Client. When I run my application, I see that MariaDB client that I put in my Java JRE directory already loaded. It does not happen with MySQL driver that I have been using. So the question is: does MariaDB clients have a feature that Java recognizes and loads the Client automatically?
Yes, autoregistration is part of JDBC 4.0, which came wiith Java 6 , in 2006 The connector/j driver you are using is probably quite old if it does not have this feature.
The exception I have is "java.nio.BufferUnderflowException"
Yeah, in the long past the packet server sent was on new connection was shorter according. So underflow exception can be explained.
