Re: Communication Error

Please make sure you have your connection string correct.

If you don't know for sure that there is connectivity between your client host and the MySQL server you can try opening a telnet session to your server's host and port from the client machine: "telnet <host> <port>", replace "<host>" and "<port>" by the ones you have in the "jdbc:mysql:" connection string. If it works you should see a few garbled chars and the server should close the session after a few seconds of inactivity.

Please post your findings.
