Spring, Interceptors and AspectJ

[MmarcoM]

hello all,
i have written an application that uses Spring and Hibernate to retrieve some data from database...
I have implemented AOP around advice using spring aop functionality, but now (just for trial), i wanted to replace spring AOP with AspectJ.
for spring AOP, i had to define proxies and interceptors (also for transaction purposes)...
my applicationContext.xml is as follows

<beans>

the problem is my HibernateStockDAOImpl./
i am using an advisor containing an around advice, using spring aop functionality.

I have written a similar aspect using aspect j, and here is the code

---CODE----
public aspect QueryAspect {


pointcut query(com.myapp.hibernate.HibernateStockDAOImpl dao) : call(* com.myapp.hibernate.HibernateStockDAOImpl.*(..))
&& target(dao);


before(com.myapp.hibernate.HibernateStockDAOImpl dao): query(dao) {
System.err.println("--------- BEFOREAspectJ around advice....." + thisJoinPoint);

}

after(com.myapp.hibernate.HibernateStockDAOImpl dao): query(dao) {
System.err.println("--------- AFter around advice....." + thisJoinPoint);

}
}


I was expecting that my AspectJ before & after advices were going to be called every time HibernateStockDAOImpl method gets called (so, even before the query method defined for the StockAroundAdvice.

Instead, i found out that they are called ONLY from my StockAroundAdvice.around advice.

Only guess that i can make is that behaviour is like this because my HibernateStockDAOImpl is wrapped in a Proxy ...
But if i don't wrap it in a proxy, i will lose AOP transaction functionality...

anyone can help? hope i was clear enough to explain my problem..

thanx in advance and regards
