LazyInitializationException *not* showing up when it should

ninjapowered · **Joined:** Sun Feb 19, 2006 3:50 am **Posts:** 34

Summary of my question: According to the docs I've read, lazy-loading cannot occur outside the scope of a transaction unless auto-commit is on. I've verified that auto-commit is off in my app, so why is lazy-loading working outside of a transaction?

The details:
I'm trying to implement the Open Session in View pattern, and I've been debugging my progress as I go along to make sure I understand what's going on and am doing thing properly. In one of my tests I was expecting to get a LazyInitializationException but I didn't, and I'm hoping someone can help me understand why.

According to http://hibernate.org/43.html "some developers are using a variation of this pattern that keeps the Session open until the view has been rendered, but commits the database transaction before rendering of the view. The consequences are the same as not keeping the Session open: lazy loading does not work outside of a database transaction. It doesn't matter if the Session is still open, it has no connection."

Based on that information I was expecting to get a LazyInitializationException when I committed a transaction and then accessed a lazy collection without starting another transaction, but it successfully lazy-loaded the collection without throwing an error. The next part of the URL above states: "further confusion appears when this anti-pattern actually works, but simply because the auto-commit mode is actually in use." I've verified that the connections I'm getting back are not auto-committable, so I don't know why it's not throwing an error and I want to know why to make sure I don't have some settings on that would cause poor performance or other errors down the road.

I'm using Hibernate 3.1.2, Tomcat 5.5.9, Struts 1.2.8, and MySQL 4.1.18 as the database. No J2EE container. Windows XP.

Here's the code that I'm expecting to throw a LazyInitializationException but doesn't (if it matters, I'm doing this inside a Struts Action):
------

Code:

Session session = HibernateUtil.getSessionFactory().getCurrentSession();

session.beginTransaction();
Person person = (Person)session.get(Person.class, new Long(1));
session.flush();
session.getTransaction().commit();

List itemList = person.getItemList();
//this should throw a LazyInitializationError. Why doesn't it?
Iterator iterator = itemList.iterator();

------

With debugging I've verified that itemList is null after person.getItemList() and is lazy-loaded on the itemList.iterator() call. My app is using an extended ThreadLocalSessionContext in order to prevent flushing and session closing. Here's the code for that (minus comments):
------

Code:

package com.testapp.dal.hibernate;

import org.hibernate.ConnectionReleaseMode;
import org.hibernate.FlushMode;
import org.hibernate.SessionFactory;
import org.hibernate.classic.Session;
import org.hibernate.context.ThreadLocalSessionContext;
import org.hibernate.engine.SessionFactoryImplementor;

public class ThreadLocalSessionContextNoAutoClose extends ThreadLocalSessionContext
{
    public ThreadLocalSessionContextNoAutoClose(SessionFactoryImplementor factory) 
    {
        super(factory);
    }
    
    protected boolean isAutoCloseEnabled()
    {
        return false;
    }
    
    protected boolean isAutoFlushEnabled()
    {
        return false;
    }

    protected Session buildOrObtainSession()
    {
        Session s = super.buildOrObtainSession();
        s.setFlushMode(FlushMode.NEVER);
        return s;
    }

    protected CleanupSynch buildCleanupSynch()
    {
        return new NoCleanupSynch(factory);
    }
    
    private static class NoCleanupSynch extends ThreadLocalSessionContext.CleanupSynch 
    {
        public NoCleanupSynch(SessionFactory factory) 
        { 
            super(factory); 
        }
        
        public void beforeCompletion() 
        {
            //do nothing
        }
        public void afterCompletion(int i) 
        {
            //do nothing
        }
    }
}

My HibernateUtil is the standard recommended one for Hibernate 3.1 found in http://hibernate.org/42.html.

Here's my hibernate config file:
------

Code:

Here's the data source setup in my tomcat server.xml file:

Code:

    <Resource name="jdbc/testapp"

          defaultAutoCommit="false"
          removeAbandoned="true"
          removeAbandonedTimeout="60"
      logAbandoned="true"/>

I could include my Person and Item java files, but they're just standard getters and setters for the properties. Nothing special. Anybody have an idea on why I *don't* get a LazyInitializationException when accessing the not-yet-loaded item collection outside of a transaction? I'm happy to provide any more information if I forgot to include it here. In case the logs and generated SQL help, here's everything I get from session.beginTransaction() to itemList.iterator():

I had a similar problem about Lazy Initialization, please look at the following post:

http://forum.hibernate.org/viewtopic.php?t=955557

with name: "LazyInitializationException executing a HQL in Eclipse" on Hibernate Tool forum.

in order to see the solution I have found, probably your case could be similar to mine.

Bye,

David

Thanks for the idea David, but after looking at your post I don't think it has anything to do with my problem. My problem is that I'm *not* getting a LazyInitializationException. I'm not overriding equals or hashcode anywhere and I have no meta use-in-tostring anywhere.

According to the documentation I've found, the only way lazy initialization should work outside of the scope of a transaction is if auto-commit is on. I've verified that my JDBC connections are *not* set to auto commit. So why is lazy initialization working outside of a transaction?
