Could you doublecheck where your XML files are located (should be in
WEB-INF or WEB-INF/classes)?

Totally... with a session pattern that won't be a singleton per se.
Check out this page:

The filter setup would allow you to obtain a session DataContext with
this code within JSP's:
DataContext context = DataContext.getThreadDataContext();
