Re: Datasource in Shark

Hi,

it seems that you either didn't set properties:

DatabaseManager.DB.<database_id>.Connection.ConnectionFactory = com.lutris.appserver.server.sql.DataSourceDBConnectionFactory
DatabaseManager.DB.<database_id>.ConnectionAllocator = com.lutris.appserver.server.sql.datasource.DataSourceConnectionAllocator

or you didn't include dsconnection.jar in your classpath, so the above specified classes can't be found.

Regards,
Sasa.
