Re: Unable to connect using Connector JDBC

Hi,

Do you have a firewall blocking traffic from port 3306 on the machine running the MySQL Server?

The JDBC Connector has nothing to do with this issue. It just establishes a TCP connection to the given IP and port. If your network infrastructure is blocking it there's nothing it can do.

You can test connectivity between client and server machines by executing this simple telnet command in a client shell:
$ telnet 192.168.nnn.nnn 3306
If you get some response from the server, you should also be able to connect using Connector/J or workbench.

IHTH
