Basically it is happening when I call "query.list()", in a method of one of the HibernateDAO classes of my project. I'm also using JTA UserTransaction API directly to control my transaction.

Thanks in advance for any help!

Cristina

Check if your session is open when you do query.list().

Hi,

Yes, my session is opened and connected.

I've called session.isOpened() and session.isConnected() to verify, and both return true.

In fact, when query.list() is called by the first time, the java.lang.ExceptionInInitializerError problem does not happen.
In this case, the session is opened, connected and dirty.

The java.lang.ExceptionInInitializerError problem happens when query is called by the 2nd time, and in a situation where the session is opened, connected but is not dirty...

Any other hint?

Thanks in advance for your help!

Cristina

Can you please post the code between session.open() and session.close(). I got this issue before and it was due to session. Have to see your code to be sure.

Hi Sukirtha,

I'm using JTA UserTransaction API directly to control my transaction, so I'm not calling directly session.open() and session.close(). I'm assuming that the session is being opened when I start the transaction, and that the session is being closed when I commit the transaction.

The code that starts the transaction and depending on the result, commit/rollback is:

try {
trans = (UserTransaction)
new InitialContext().lookup("java:comp/UserTransaction");
trans.begin();

IPortfolioDAO dao = (IPortfolioDAO)
ComponentLocator.getInstance().
getInstanceOfType(IPortfolioDAO.class);

// !!! --------------------------------------------------------------
// !!! THE PROBLEM HAPPENS WHEN THE FOLLOWING
// !!! METHOD IS CALLED
// !!! --------------------------------------------------------------
List portfolio = dao.selectByContext(contextKey);

trans.commit();
transactionSuccess = true;

} catch (Exception e) {
throw new SystemException(e.getMessage(),
e.getCause(),
"errors.user.portfolio.access");
} finally {
if (transactionSuccess == false) {
try {
trans.rollback();
} catch (Exception e) {
e.printStackTrace();
}
}
}

------------------------------------------------------------------
Here is the code of selectedByContext method...

public List selectByContext(String contextKey) throws InfraException {

final String portfolio = this.getVOClass().getName();
final String className = this.getClass().getName();

List list = new ArrayList();

Session session = hibernateUtil.currentSession();

try {
String hql = "select p from " + portfolio + " as p"
+ " where p.ctxPart.contextID = :id";

Query query = session.createQuery(hql);
query.setString("id", contextKey);

// !!! ----------------------------------------------------------------
// THE java.lang.ExceptionInInitializerError HAPPENS HERE!!!
// !!! ----------------------------------------------------------------
list = query.list();


this.initializeCollection(list);

} catch (Exception e) {
throw new InfraException(e.getMessage(),e.getCause());
} catch (Throwable e) {
throw new InfraException(e.getMessage(), e.getCause());
}
return list;
}


The code of hibernateUtil.currentSession() is:
public Session currentSession() {
return factory.getCurrentSession();
}

where factory is being initialized with the following code:

factory = new Configuration().
configure(hibernateConfig).buildSessionFactory();

hibernateConfig is a file with the following contents:

Please let me know if you need any further information, ok?

Thanks in advance for your help!

Cristina

Where does the error occur?

(or)


To make sure, comment the second line and try executing your code. I feel lazy initialization is not happening under certain scenarios. I am not sure though!

Ciao Cristina,

java.lang.ExceptionInInitializerError usually means there is some exception thrown in some static initialization block, do you have static code in you entities?

Could we see the source of the entities you are trying to get a list of?
is it "br.fapesp.tidia.ae.common.portfolio.commontypes.vo.RootVO" ?

Hi Sukirtha,

The error occurs when the line "list = query.list();" is executed. Even if I comment the line "this.initializeCollection(list);", the error stills there.

What looks more strange to me is that I'm not using lazy classes in my project, and in the error stack trace I see "org.hibernate.proxy.CGLIBLazyInitializer.getProxy(CGLIBLazyInitializer.java:99)"... Isn't strange a lazy initializer method being called, even when there is no lazy class or attribute in my project???

Thanks a lot for your help!

Cristina

Ciao Sanne,

I don't have static code in my entities :(

The entity I'm trying to load is PortfolioVO. This class has an attribute of type RootVO.

I'm sending the code of these classes... Maybe you can see a problem...

Thanks in advance for your help,

Cristina

Hi,
I'm really sorry I don't see any problem related to this issue in your entities,
but I never used this mapping style.
You are probably mixing some library versions, did you verify you are using the same cglib that comes with your hibernate version?

Besides this, I've seen some "unusual" style in your code,
if I may advice you about your toString() methods, if you use StringBuffer (good idea) or StringBuilder (even better) you shouldn't use the "+" sign but issue separated .append() statements.

And please if you have to post so much code use the "code" function, so it gets more readable.

Finally, you should really post your library versions so that hibernate experts can help you out.

regards,

Hi,

I'm using hibernate-3.2. I've already checked and I'm using the same cglib that comes with hibernate.

Thanks for the advices related to toString method and to "Code" style. I will certainly follow them from now on.

Regards,

Cristina

Can we see your mapping files for RootVO and PortfolioVO.

Hi Sukirtha,

Here they are. Note that RootVO is a subclass of FolderVO.

Thanks!

Cristina

Sorry Cristina... Don't see any problem with your mapping files as well.

Hi Sukirtha,

Thanks for your help. In fact, I'm now wondering if the problem isn't related to the fact that PortfolioVO object has a RootVO member variable, which is a "subclass" from hibernate perspective...

I have a similar persistence class in my project (WeblogVO), for which the problem never happens. And the main difference between PortfolioVO and WeblogVO is that WeblogVO does not have member variables which are "subclasses" from hibernate perspective.

Just to give you more information of the context where I found this problem:
my project was originally designed to use JBoss and EJBs. All the persistent classes are exactly the same, and we have never had this problem.
Now we've been requested to not use JBoss and EJBs, and we will run now under tomcat only. So, our transaction control now is based on calls to UserTransaction API directly. In terms of persistent data, there has been no change in my classes. The only change has been in my HibernateDAO classes: before they were calling session.open, session.close, commit or rollback. Now they only get the current transaction, which is opened by the system component of my project...

I have been reading the Hibernate documentation, looking for help about how to handle with inherintance objects in persistence classes. I saw a small section in Chapter 4 of the Hibernate Core documentation. Would you have more references about how to handle or how to avoid inherintance objects is persistence classes? If my suspection is true, I will need to get rid of this "sublcass" RootVO...

Thanks again for your help,

Cristina
