Hi,

I'm running Connector/J 2.0.14 with J2SDK1.4.1_01. Prior to these upgrades, all my code ran fine. However, I upgraded all my packages (MySQL, J2SDK, and to Connector/J, as already stated) and now I keep getting an IOException. Why is this happening? I've thought about the timeout scenario but there arent any links at all, and adding autorefresh doesnt help since it never gets the connection to begin with. The stack trace finds it errors in the Connector/J init attempts. Anyone have any thoughts?

Are you running Linux? Various versions of Linux (RedHat, mostly) have issues with TCP/IP connections being made to various versions of MySQL server. You should ensure that you are using MySQL-4.0.9 or newer from MySQL-AB binaries (not RedHat), and that connecting using TCP/IP from the mysql command-line client works.

See http://www.mysql.com/doc/en/News-4.0.9.html
