In this case I'm perfectly all right. My servlet has just about 20 lines
and does call a class. This class instanciates a "Database-Accessing"-
Class (WebSQL) because I started with access to MS SQL server and now porting
to PostgreSQL. I just have to change WebSQL to use another database
engine. All the connections, statements etc are private in this
class. But I wanted to avoid to declare this stuff in every method
of this class.
Kind regards
Andreas.
