AEM 6.5 No data source found with name

Hello, I was trying to connect MySQL to AEM using Service but I got problem while doing it. Can you help me identify where the problem is?
DatabaseService.java

Here's my the datasource configuration

and the bundle that I've been using for the driver class

Here's the error I got from logger of my service.

com.ravens.core.servlets.DatabaseService ERROR OCCURED {}
com.day.commons.datasource.poolservice.DataSourceNotFoundException: No data source found with name 'my database' (after asking 0 providers)

Thank you in advance
