Steve could you say a couple of words about jboss-hibernate integration development status regarding jboss 4 release. I see you removed most of the session management code... When and where we'll see it again? And what will it be look like?

The only "thing" I removed was the notion of scoping to a thread. Removing this also removed the need for interceptors, so they were removed (really they were only there to support thread scoping). Obviously, this makes usage much easier and allows support of all the use cases we had set forth for this to acheive.

So what is in CVS *is* the jboss-integration; nothing else to see; this will be effective in 3.2.6, 4.0, and 4.2/5.0.

I did Wiki this change, but forgot to mention it here.

Also note that HibernateContext does now expose all of its "lifecycle" methods (bind/unbind/prepareSession) so that applications can define their own lifecycle semantics. However, the *access* still needs to be within the bounds of a JTA transaction because of the use of the TransactionLocal used internally.

I have a problem in Jboss Release 4.0.0 + Hibernate+ mysql + servlet test.

I deploy a har in jboss4, it works good.

But when I test a servlet , which use HibernateContext.getSession(..) to get the session, i get an error.

I traced into the jboss-hibernate.jar and found in function HibernateContext.prepareSession():

...
try
{
context = new InitialContext();
TransactionManager tm = (TransactionManager) context.lookup("java:/TransactionManager");
tm.getTransaction().registerSynchronization( new TransactionSynch(name, session) ); //##got error here
}

......

in servlet , code like :


Session session = HibernateContext.getSession("java:/hibernae/SessionFactory");


Did i miss something ?
In Jboss 4.0 , no filter needed, is it right?

I think the 4.0 release did not have these most recent changes. Take a look at the HibernateContext class. Does it have a static variable named SESSIONS of type TransactionLocal?

If not, this is the older code. You'd need to get the newer code and build the jboss-hibernate.jar

Otherwise, what is the exception you are getting?

Thanks steve.

The problem resolved.

Here is how:
=====
InitialContext ctx = new InitialContext();
UserTransaction utx = (UserTransaction)ctx.lookup("java:comp/UserTransaction");

utx.begin();
=====

insert above code before HibernateContext.getSession(...)

and it works.


I want to know, is it the normal way to access hibernate seesion in a servlet?

Generally, access to a Hibernate Session occurs within a transaction; yes.
