Can't connect to local DB using IP instead of localhost

[Maxim Markaitis]

Java program connects via jdbc:mysql://localhost:3306/customers fine.
Buf if to replace localhost with my IP "jdbc:mysql://111.222.333.444:3306/customers" I receive:


com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: 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.

I need my server could be connectable from another hosts.
How to configure this?
I use MySQL 5.2 running it as a service.
