[Rod J. <rod...@in...>]

Juergen,

Thanks (I think).

That's weird: did you commit it? I can't see it.

I've just fixed it by re-introducing an inner class CglibProxyFactory: Gr=
ab
the current AdvisedSupport from CVS, and a JDK proxy will work with
Hibernate 2.1 - without the need for cglib1.jar in the class path. I've
tested it with Petclinic, and it works nicely.

We should stick to that inner-class strategy when migrating to CGLIB2, to
let people use Hibernate 2.0.x or iBATIS Database Layer (with CGLIB1
underneath).

Juergen

I guess in my refactoring I lost the indirection by which a CGLIB proxy w=
as
created only by an inner class, to prevent dependence on CGLIB at runtime.
I'll try to sort that out tomorrow or Monday.

Btw, the TransactionProxyFactoryBean now extends the new ProxyConfig, whi=
ch
has a proxyTargetClass property that defaults to false. Set it to true to
force CGLIB. Otherwise it won't use CGLIB by default.

Regards,
Rod

poses the question whether we should still release our 1.0 M4 with CGLIB1
support. Of course, our current codebase works nicely with Hibernate 2.1 =
as
long as you don't use CGLIB-based AOP proxies (i.e. proxy full target
objects instead of just interfaces), so we don't *have* to update
immediately.
