Connection verification failed for data source

I am running windows7, cf8 entrprise, and have setup several databses successfully. For some reason this one isn't working.

Datasource: colcadbase

Driver: other

CF Data Source Name:colcadbase

JDBC URL: jdbc:mysql://localhost:3306/colcadbase

Driver Class: com.mysql.jdbc.Driver

When I try to verify the dbase, I get the following error:

Connection verification failed for data source: colcadbase

java.sql.SQLException: Timed out trying to establish connection

The root cause was that: java.sql.SQLException: Timed out trying to establish connection

Any ideas what is happening here?
