Subject [jira] Commented: (WW-3127) Autoware fails on proxied objects

-----------------------------------

Thank you for trying to help.
Better solution for my particular problem (I need JPA transaction) is to create interceptor
and stick it somewhere before parameters interceptor.
I reported this problem only to let you guys know about it.

I checked the link you gave me. We do not use <aop:*> directly. Not sure how to force
CGLIB. THough I already realized that I was wrong about CGLIB. Apparently it really creates
proxy in front of the actual bean. So though unconfirmed I think CGLIB proxy will fail too.

In addition to that, I just figured out that Struts does not like actions to be proxied, period.
 OGNL is not getting properties from JDK proxied beans unless getters are part of interface.
It would be nice to teach Struts to "unproxy" JDK proxies when evaluating expressions.

Anyway. Not sure if something can or should be done until Struts will be able to handle JDK
proxies.

> com.opensymphony.xwork2.spring.SpringObjectFactory#buildBean method calls autoWiringFactory.applyBeanPostProcessorsAfterInitialization()
method.
> In some cases this method can return a JDK Proxy instead of action. Following call to
autoWireBean method attempts to autowire proxy itself instead of the action.
> As a result the action remains "not-wired".
> May be autowiring should happen before applying post processors "AfterInitialization".
