a custom place via the setApplicationContext call. That should be fine: I=
 suppose that the error you're getting has other origins. Autowiring has =
been significantly reworked; could you check for which components you get=
 more than one matching bean? The reason could be that you actually *have=

elevant parts of your configuration?
