I have encountered the same kind of problem with JBoss4.0.3SP2, when I replaced
hibernate3.jar in the lib folder with the newer one. DB is Oracle 10g. So maybe
it doesn't work that way..
The reason, why I'm trying this at all, is that we have very serious problem

Hello,
For completeness, this problem has been solved.
The cause was that my own implementation of ManagedConnectionFactory (in the
resource adapter) was not serializable.

Using the Lucene API is not the problem. Looks fairly simple to get going.
The problem is that it says that you can set up annotations to have Hibernate

In fact, as well as hooking automatic Lucene updates in, you shoul

Luckily i already made a 'workaround' for the issue: i simply created an extra,

I read in the sun forums that in EJB 2.0 you cannot have a primary key that
contains a field that takes part in a relationship i.e the foreign key. This is
in case of a one to many relationship. In a one to one relationship it is
possible.

in terms of table.column but in terms of object.attribute. So the correct query
is:

findByArticle(java.lang.String article)"

An addition: could it have anything to do with the fact the "article" is a CMR

"article")?

Hello,
Something I forgot to mention in the previous post is that (de)serializing the
mentioned dialog object works just fine in a stand-alone application using the
following code:
| ByteArrayOutputStream bs = new ByteArrayOutputStream();
| ObjectOutputStream os = new ObjectOutputStream(bs)
I've looked at both JBoss and Hibernate source, and I am thinking the quick
answer is NO. At least in JBoss 4.0.3.
Currently, the JBoss Hibernate MBean uses a Configuration object to initialize
the session factory. In order to support annotations, it will need to use an
AnnotationConfiguration
We didn't get any help from the JBoss people. We did create our own
connectionProvider to return the connections. We used ThreadLocal variables to
set database session information as each connection was retreived. That meant
that we had to use "after_statement" release_mode in hibernate, which i

Hi Scott,
I have downloaded JBoss-4.0.3SP1 and installed (using installation option -
''all''). But I don't find the directory 'licenses' under 'docs'. It only
contains 'dtd', 'examples' and 'schema' directories.
Regards,
Jitendra

Use the fully qualified class name of the DTO you want to use. i.e.
com.company.BasicModelDTO.

Hi,
But if I need to use CMT and into EJB I have DAOs methods
that manage transactions and sessions?
This DAOs methods are used in EJBs and Web Applications.
What can I do for this case?
thanks

Yes, you'll need to put some inexpensive select to check valid connection.
Somehting like this will do it for PostgreSQL:
select 1

Probably way too late, but I just came across this entry and having resolved
the problem myself I thought it could be interesting for others.
In my case this was because I did not use the right jdbc driver. Make sure you
use the driver provided in the 4.0.3 release of JBoss.

I found a solution by not implementing LoadEventListener, but instead extending
DefaultLoadEventListener and calling super.onLoad() at the beginning of my
onload impl.

Ok I've got it. The problem was the jdbc driver for sql server 2000. %$%$#^%
Microsoft I'm using the JTDS Driver now.

Even worse. It drops the schema and recreates it.
Include this in your persistence.xml:

I changed read-ahead strategy to on-find in the of my jbosscmp-jdbc.xml. Now
JBoss executes a query, which finds the rows and selects all fields. But it
still retrieves the very same properties using separate SQL queries. As you can
see from the log dump the row is added to the preloaded data c
301 - 400 of 659 matches
