Cause: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure

Looks like some connection issue while trying to use the connection… Is it a local MySQL database or does the db-connection go over the wire?

this happens if you do not use something like c3p0 for connectionpooling… at least in other apps with hibernate/mysql. Might be Ibatis has built-in functionality that needs to be configured. Not sure.

Ok, i have no idea what Ibatis is. Maybe Google can help me
When i need to configure this, how can i do this?

Thanks.

I have the same problem.
Did you solved it through configuration of the connectionpool ?
