Hi, we are developing an unusual applicatoin, basically centered on session
beans which manage database (not entity beans, because the data to be
retrieved are dynamic). To make our application multi-database compliant,
and following a pattern, we defined basically one Session bean for each used
database (MySQL, Oracle, SQLServer, Postgresql and other could be added).
The application then choose the right session bean depending on user
selections and this is possible thanks to a common interface which all the
database-specific interfaces inherit from. This way a client will have
simply to get a reference to the super-interface (as the methods are common
for every session bean) and polymorphism will be guaranteed. So far so good.
So far we developed the session beans manually but now I would like to
migrate to XDoclet, even because we are planning to develop other beans, and
XDoclet will be of great help.

As you will probably guess, our problem is how we could define via XDoclet
that each database-specific interface will inherit from the common one (now
is possible because all the interface was declared manually).

Any help will be appreciated.

Marco
