> Key: NETBEANS-6245
> URL: https://issues.apache.org/jira/browse/NETBEANS-6245
> Project: NetBeans
> Issue Type: Bug
> Components: db - MySQL
> Affects Versions: 12.6
> Reporter: Svatopluk Dedic
> Assignee: Svatopluk Dedic

> The db.mysql module provides an entry for MySQL driver, but an attempt to connect to a database will result an error (see the attached screenshot).
> The JDBC driver is not shipped with the module (although it IS specified in `external/binaries-list`) and the driver's URL is not supplied in mysql regitration. In fact, the mysql.xml is provided by a generic DB drivers module, but not the MySQL specific one.
> The error printed to the log is
