Re: [Springframework-developer] is LazyInitTargetSource on factories possible?

[Juergen H. <ju...@in...>]

This is not a general problem with LazyInitTargetSource on a FactoryBean:
It's rather a problem with LazyInitTargetSource on a JDK proxy as target, if
no proxy interfaces have been specified. Try specifying an appropriate
interface on your ProxyFactoryBean definition (via the "proxyInterfaces"
bean property); this should automatically lead to a JDK proxy being
generated there too.

BTW, why do you prefer your JaxRpcPortProxyFactoryBean to be lazily
initialized? To avoid checking the WSDL at startup? It would maybe make
sense to add a lazy initialization option to Spring's
JaxRpcPortProxyFactoryBean itself in this case (I'll consider this).

factories possible?


Hi,

do I see it right that LazyInitTargetSource with Spring 1.4 cannot be
applied to factory objects? Concretely, I'd want to initialize the
configured JaxRpcPortProxyFactoryBean in a lazy way and it both looks
like it *is* getting initalized on startup and it throws an exception
about trying to subclass a final class.. (see the exception at the end).

I'd need to figure out that issue as soon as possible, so any help's
greatly appreciated. Any workarounds might also help..

thanks much in advance,

Kristof
