RE: [Springframework-developer] Refreshing the ApplicationContext...

Ross,

I've just re-tested Petclinic from our current CVS HEAD against a =
dropped-in Hibernate 2.1 final (plus cglib2, minus cglib-asm), with and =
without OpenSessionInViewFilter. Works nicely for me - no VerifyErrors. =
Could you please re-try and re-report if there are still issues?

Note that the AOP framework is not migrated to CGLIB2 yet (it's in the =
works), but this shouldn't affect you at all if you just proxy via =
interfaces (the default). Simply remove cglib-asm from the class path, =
drop in hibernate2, cglib2, eh-cache - and you should be done.

Hi j=FCrgen,

Sounds interesting, anything without EJB is always a bonus in my book -=20
excuse the pun ;-)

We've actually decided to wait for the M4 release before migrating.  The =

problem is that we're using a hibernate 2.1 jar built from HEAD and I=20
was getting VerifyErrors errors when running with the latest from Spring =

HEAD due to an incompatability with the two jars.

If you would like me to test it once M4 is using hibernate 2.1 and=20
before you make the actual release I would be happy to.

Cheers,

Ross

work for specific references if you apply autowire-by-type in general.

shouldn't need that for typical usages anyway. I guess what you're =
trying to do is custom initialization of the root WebApplicationContext, =
storing it in 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* multiple matching beans, which just weren't =
found by M2's autowire implementation, maybe due to being created by =
FactoryBeans. Could you quote relevant parts of your configuration?
