I have exactly the same issue and have been struggling with it for a while. The same java code (run from Eclipse) runs on several other machines without any problem. On Windows 7 machine, it does not, same configuration of the environment as in the other OS.

I get error:
SQL Exception: Communications link failure
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.
SQL State: 08S01
Vendor error: 0
*** No connection established to a database

I have Norton NIS. I disabled the firewall, no success.
I made sure port 3306 is set ok in Norton. It was. No success accessing the database from java.

I am using the latest Jconnector: mysql-connector-java-5.1.24

MySQL server is running fine. I can connect to it from command line and access the databases and tables.

Telnet localhost 3306 gives me a connection

The java code is not the problem as it works with the same MySQL servers on other machines. I have the same server and same environment.

The only difference on that machine is Windows 7 and Norton NIS.

Anybody experiencing the same issue? Any help would be appreciated. Thanks!
