[ILUG] MySQL Problems

I suggest you check the following:
. No Firewall is running on your server
. The mysql JDBC driver is installed & configured
You can try to diagnose the problem by running tools like ethereal or
tcpdump on the port 3306 in order to check if java can send packets to
Mysql and if Mysql can answer.
You can also check for incoming connection in Mysql's server logs.
Since you can connect to your Mysql with other tools, I would think
that the problem is likely on the java part.
