I'm trying to do the same thing here, but I'm not sure on a few
of the details.
I've got a servlet called DatabaseContainer, which will handle all
the database connections and populating Beans to send back
to the Actions.
What I can't work out is, once I've get the DataSource, how does the
Action know about the DatabaseContainer? At the moment I've
got
getServletContext().setAttribute("DatabaseContainer", this);
and so in the Action, I can call
DatabaseContainer database = (DatabaseContainer)
servlet.getServletContext().getAttribute("DatabaseContainer");
But this doesn't seem right. Since Craig doesn't like singleton objects
hanging around, and I don't feel like I want to extend ActionServlet,
this seems like the only way (since getServlet() is depreciated in the
2.2 spec).
Any ideas?
