Datanucleus + OSGi (Equinox) gives an error. No suitable driver found for jdbc: mysql: // localhost: 3306 / jdoosgitest

I try to use the datanucleus jdo implementation inside the osgi environment, but I constantly get the error: no suitable driver was found for jdbc: mysql: // localhost: 3306 / jdoosgitest

I followed the link http://www.datanucleus.org/servlet/wiki/display/USERS/HOWTO+Use+Datanucleus+with+OSGi+and+Spring+DM

But I do not want to use SpringDM. Firstly, because I don't know Spring, and I'm new to OSGi and JDO.
