New JBoss - Hibernate iteration complete

steve · **Posted:** Mon Aug 30, 2004 4:47 pm

The second iteration of the integration code is completed and checked into JBoss CVS. Changes include:

New managed operation on the MBean rebuildSessionFactory(); after changes to the MBean properties, perform this managed operation to rebuild the session factory and notify MBean listeners; the MBean tracks changes to its properties and exposes the fact that it has changed via the new "dirty" RO managed property
Event generation when MBean's SessionFactory is built or destroyed
SessionContext is now aware of changes to MBean's SessionFactory through event notifications
Added ability to retreive "unmanaged" session from SessionContext (useful for Hibernate callback handlers)
Added ability to define Hibernate Interceptors; the Interceptor must have a no-arg constructor; it can be registered with the MBean (for factory-scoped interceptor) or with the session management interceptors (for session-scoped interceptor)
Session management interceptors now accept an "explicitFlush" config parameter; if true (the default), the session will be flushed prior to unbinding and closing

It will be available in the next JBoss 3.2.6 release, or you grab and build it from CVS.

I'll update the Wiki when I get a chance to reflect these new changes; just wanted to give y'all a heads-up.

Cool. Will it make it into 4.0.

steve · **Posted:** Tue Aug 31, 2004 11:09 pm

Should. I'll double check

steve · **Posted:** Fri Sep 03, 2004 12:42 am

Yes, this will be in 4.0 final.

Just tried in JBoss 4.0RC2. It appear to mainly included here too, but have not got it to work yet.

1) EhCacheProvider not in the hibernate2.jar shipped with JBoss. The hibernate2.jar must therefore be older than hibernate 2.1.5.
So I replaced the hibernate2.jar with that from 2.1.6

2) I did everything else. HibernateService and HARDeployer start OK. HibernateService is in JNDI at usual place. However, when my EJB looks up the HibernateService, I get an IllegalStateException runtime exception which I catch and log as below.

Code:

Hi,

I guess you haven't added the SessionFactoryName tag to your hibernate-service.xml which is included in the HAR file.
Mine looks like:
<mbean code="org.jboss.hibernate.jmx.Hibernate" name="jboss.har:service=HibernateTicketsystem">
<attribute name="DatasourceName">java:/PostgresDS</attribute>
<attribute name="SessionFactoryName">java:/hibernate/SessionFactory</attribute>
<attribute name="Dialect">net.sf.hibernate.dialect.PostgreSQLDialect</attribute>
<attribute name="CacheProviderClass">net.sf.hibernate.cache.HashtableCacheProvider</attribute>
<attribute name="ShowSqlEnabled">true</attribute>
<attribute name="DefaultSchema">public</attribute>
</mbean>
and I'm using JBoss 3.2.6 and 4.0.
Hope this helps

David,

We've been discussing with Steve here http://forum.hibernate.org/viewtopic.php?t=933927 about some issues of the current jboss-hibernate integration stuff.

Recently, Steve added bindName parameter which is optional and should be equal of jndiName by default.

But there's a small bug in current version (Steve, fix it please).

Code:

this.explicitBindName = bindName != null;

should be

Code:

this.explicitBindName = (bindName != null && bindName.length()!=0);

This is because for absent servlet filter parameter null is returned, but for ejb interceptor

Code:

            <interceptor service="jboss.har:service=Hibernate" scope="transaction">org.jboss.hibernate.session.EjbInterceptor</interceptor>

config.getAttribute("bindName") returns an empty string.

David, by the way as you're using this stuff - maybe you could share your opinion about things we're discussing at http://forum.hibernate.org/viewtopic.php?t=933927 ?

octopus · **Posted:** Wed Sep 08, 2004 11:00 am

David - just to clarify my previous post - this bug is the source of your exception.
While it's not fixed, just add explicit bindName in interceptor description.
bindName="java:/hibernate/SessionFactory"

steve · **Posted:** Thu Sep 09, 2004 7:31 am

I actually just removed the bindName stuff.

I also renamed SessionContext -> HibernateContext. I never really liked the SessionContext name because of the name clash with javax.ejb.SessionContext.

I also implemented what is hopefully a fix to the issue you are seeing. Essentially, the HibernateContext stuff is now using ENC internally to store the "current session". This is a bit verbose currently due to jboss naming not being able handle non-serializable objects as bind values. Currently this stuff is only in HEAD. I'll move it to the 3.2.6 branch as soon as I get time. In the meantime, you're more than welcome to build that module from HEAD and drop it into your 3.2.6 install.

Thanks, Steve. This is exactly what I initially suggested. Seems to work perfect by now..

One bug found: in TransactionSessionStorage$TransactionSync
session.flush() should be moved from afterCompletion() to beforeCompletion() and there HibernateException should be rethrown as runtime to make TM rollback transaction in case hibernate cannot persist changes.
(or is there a better way to setRollbackOnly from beforeCompletion() ? )

david.wade · **Posted:** Fri Sep 10, 2004 1:15 am

Thanks for the input everybody.

I took the easy option of downloading the latest source and rebuilding jboss-hibernate.jar. This allowed everything to be done as per the wiki with the exception of using

Code:

org.jboss.hibernate.session.HibernateContext.getSession("java:/hibernate/SessionFactory");

instead to get the session.

octopus · **Posted:** Fri Sep 10, 2004 5:09 am

Correction to my previous post: rethrowing exception is not necessary indeed, since hibernate itself initiates rollback in case of error.

But moving flush() still necessary.

I have JBoss 3.2.5, Hibernate 2.1 and mySQL 4.0.18. Does that mean I have to wait that long to integrate Hibernate with JBoss? If not, any easy solution for a newbie?

You can use it with just about any version of JBoss. Just create a JBoss .sar file and deploy it. Below is an example jboss-service.xml that I've used with version 3.2.3 and 3.2.6. Search the Hibernate forums for more info, and also see http://www.hibernate.org/66.html for some detailed instructions.

<server>
<mbean code="net.sf.hibernate.jmx.HibernateService" name="jboss.jca:service=HibernateFactory,
name=HibernateFactory">
<depends>jboss.jca:service=RARDeployer</depends>
<depends>jboss.jca:service=LocalTxCM,name=Ora9DS</depends>
<attribute name="MapResources">
<snip> put your hibernate mapping (.hbm.xml) files here
</attribute>
<attribute name="JndiName">java:/hibernate/SessionFactory</attribute>
<attribute name="Datasource">java:/Ora9DS</attribute>
<attribute name="Dialect">net.sf.hibernate.dialect.Oracle9Dialect</attribute>
<attribute name="TransactionStrategy">net.sf.hibernate.transaction.JTATransactionFactory</attribute>
<attribute name="TransactionManagerLookupStrategy">net.sf.hibernate.transaction.JBossTransactionManagerLookup</attribute>
<attribute name="ShowSql">false</attribute>
<attribute name="JdbcBatchSize">0</attribute>
<attribute name="UserTransactionName">UserTransaction</attribute>
<attribute name="Dialect">net.sf.hibernate.dialect.Oracle9Dialect</attribute>
<attribute name="CacheProvider">net.sf.hibernate.cache.TreeCacheProvider</attribute>
</mbean>
</server>

Would it be possible to add MinimalPutsEnabled as an attribute of org.jboss.hibernate.jmx.Hibernate?
