JPA 2.0 em.merge() firing select statements only (no update)

[Juggy Obhi]

Hi,

I need help to understand what exactly is wrong with my logic as per JPA2.0 (Hibernate 3.5).

method1(){
Object xyz = em.find(Object.class,pk);
// make lots of changes to object xyz
.....
.....
.....
//Save changes
callTransactionMethod(xyz);
}

@Transactional
callTransactionMethod(xyz){
em.merge(xyz);
}

My problem is that i see em.merge() firing only select statements. I could not see any update statements. I know i am doing some basics wrong but i have not been able to get it. Please guide.

It took me almost a day to found this -

In proxy mode (which is the default), only 'external' method calls coming in through the proxy will be intercepted. This means that 'self-invocation', i.e. a method within the target object calling some other method of the target object, won't lead to an actual transaction at runtime even if the invoked method is marked with @Transactional!


I hope this will same time for some one.
