Other Hibernate DAO LazyInitializationExceptions

[bernardsirius]

In my Web controller, I'm using a service that gets me User objects, like this:

bernard = system.getUser ("bernard");

on the next line, I'm using this object as a parameter to another method call:

boolean granted = system.checkPermission (null, "/", ResourceNames.contactPermissions, bernard, CREATE);

in the body of that method, I'm doing the following:

boolean checkPermission (...) {
  Collection groups = user.getGroups ();
  ...
  if (groups!=null) {
    for (Iterator it=groups.iterator(); it.hasNext(); )
}

the call to iterator() however, causes the LazyInitializationException.

When, on the other hand, I "re-initialize" the reference to the User object prior to the user.getGroups() call, like this:

List users = session.find ("from fractals.psychos.core.system.entity.User user WHERE user.username=? AND user.password=?",
              new Object [] {user.getUsername (), user.getPassword ()},
              new net.sf.hibernate.type.Type [] {Hibernate.STRING, Hibernate.STRING});
user = (User) users.iterator ().next();

...the exception isn't raised anymore.

Looks like, two separated calls on a facade involve each a new Session...

It's been over a week now that I fight this problem: this is way too much for a framework that's supposed to simplify my life!

Unless you're using "open session in view" you need to get Hibernate to materialize any lazy relationships in your service layer, within the transaction.

Looks like, two separated calls on a facade involve each a new Session...

They will, if they are in different transactions. And the session will be closed by the time your web tier code is handing the persistent objects, if you're using the usual approach with transaction management around your service layer.

What you're experiencing seems to be a normal consequence of Hibernate (or other ORM) lazy loading. However, please post your config (especially that showing your transaction configuration) if you're still puzzled.

The following is a bit unclear to me:

Unless you're using "open session in view" you need to get Hibernate to materialize any lazy relationships in your service layer, within the transaction.

Have you got any idea of a solution to my problem: if I understand what you mean, what I'd really need is to setup transactions that span several calls to the service layer.

I mean this is completely natural: have a service that sells fare tickets, another that sells concert tickets, and a last one that makes room reservations, all that has to be wrapped in a single transaction, to be commited at once when everything has been done. How to do that in Spring?

Have you got any idea of a solution to my problem: if I understand what you mean, what I'd really need is to setup transactions that span several calls to the service layer.

I mean this is completely natural: have a service that sells fare tickets, another that sells concert tickets, and a last one that makes room reservations, all that has to be wrapped in a single transaction, to be commited at once when everything has been done. How to do that in Spring?

You should use a single service layer method that invokes other methods to do each task. The single service layer method should define a transaction. Transaction propagation will then take care of each individual method running in that transaction, even if those methods are themselves transactional to allow separate use.

[bernardsirius]

(if I may ask) how do I "define a transaction" ? and is it possible to do this in client code (i.e. in my web controller) which would completely close the case for me...

thanks for your help. I feel relieved

Bernard,

Check out chapter 7 of the reference manual for information of transaction management. You can use both a programmatic and declarative mechanism for defining transaction semantics and both are detailed in the reference manual.
