So, to answer Harald's question, he should use Serviceable instead of

Afaik, this is not considered a bug :) Cocoon is based on the ECM which
is a ComponentManager. But you can use Serviceable and in that case
still the ComponentManager is used which requires the Component interface.
So i changed my Generator to not implement the Composable but the 
Serviceable interface. But that didn't work either. Here is my 
service-method:

public void service(ServiceManager manager) throws ServiceException {
  System.out.println("in Service");
  serviceSelector selector =
                        (ServiceSelector) manager.lookup(
                                DataSourceComponent.ROLE + "Selector");
  this.datasource = (DataSourceComponent) selector.select("vrgis");
}
Is this method right or do I have to implement something else here?
