Subject Re: AW: intercepting 'initialize-method'

I would suggest that you are doing two different things here:
initializing your service (which is meant to be trivial and error
free) and preloading your database data.  Obviously, the second of
these is the one that needs transaction support.

You have a few options, such as seperating the cache logic from the
database access logic.  The cache service can then invoke methods on
the database access service, which can be properly intercepted.

You could also lazily initialize your cache on each service method
invocations, but that's pretty ugly (it's the opposite of what
HiveMind should do).

I am initializing object-cache from the database in the initialize-method... 
My interceptor is the "transaction-interceptor" which starts transaction 
and manages the db-connection...

Yes, you can intercept it, but the interceptor won't be called when
the instance is constructed.  Any subsequent calls to the service's
initialize method (through its proxy) will use the interceptor.  The
BuilderFactory calls the initialize method on the service
implementation object directly.  Of course that's probably NOT what
you want to do (call the initialize method directly).  What are you
trying to do?  Why do you need to intercept your initialize method? 
Maybe we can come up with another way to do it.

Hello, 

I am wondering whether it is possible to intercept the the method used
as 'initialize-method' for the service.

In my tests the hivemind seems to call the 'initialize-method' of the
_inner class directly ignoring all interceptors defined for the

Service although the method is declared in the service interface. 

Thanks
