what you would normally do is model a dependency from the controller class to a 
<<Service>> class, everything is explained here: 



in this service you will then call the required code to perform your operations 
on the persistence layer (as mentioned here: )



just make sure your <<Service>> in turn has a dependency to an <<Entity>> so it 
has access to the DAO (service.getEntityDao()) and subsequently can call the 
methods to create/update/find/remove stuff from the DB



this only works this way when using Spring, for the other cartridges there are 
other things you should do, like using one of the generated util classes...
