Hi!
I am writing a small EJB3 Service app, which should call the EJB2 app. The code
looks like this:
|
| @Service(name="MyService")
|
@Depends("jboss.management.local:J2EEApplication=EJB2App.ear,J2EEServer=Local,j2eeType=EJBModule,name=EJB2App.jar")
| class MyManagement implements Man
Hi!
My Idea is to send or not to send a message according to the boolean
parameter in the afterCompletion method. But thank you for the code. So far I
have not seen any problems with afterCompletion event as well, but I want just
to be sure, if it is fine, there is nothing specific about it.
Hi!
No, flush() does not mean commit. There was already a topic and we have a lot
of problems with this issue. See the following topic:

We have implemented our own security mechanism, but I think there should be
something in JMS implementation.

Hi!
I was planning to implement it. My idea was to implement the MDB, which is
listening to the messages and giving the result back to the client, i.e. during
the execution your state/less/full bean sends messages to MDB, MDB does the
rest.

Hello!
I was deploying my app as ejb3 jar. now I migrated to .ear as I would like

I also implemented the Hibernate interceptor and injected it with
post-commit-update tag in persistence.xml. I still have the same problem.

In addition to, I have the following question. If I am calling my update()
method from the client, may I be sure that after this call from the same client
from the same thread I will NOT receive the old data?

Hi!
Thanks a lot for your answer. I actually want not to update the entity from
the second thread, but just be sure, that the entity I am reading is
up-to-date. And, of course, @Version, optimistic locking does not help me in
this case. In general, let's assume the following scenario.

Hi!
I am tracing my flush() statement, and I am sure that is happens before I am
trying to read the data.
If I understand it correctly, flush() is commiting the data and with the next
manager.createQuery run the new data should be available.
Is it true, or flush() is doing some background

This line exists before the Stateless Bean implementation.

Hi!
We are using Oracle 10g, it is the XA datasource. JBoss version is 4.0.4 GA.
For the version information I just added the column in my table, so I did not

I have the following problem. In our project we are using the standart

Sorry, but the only details I can give you are, that we have 20 Entity Beans, 1

Some extra service and session beans which are doing some background job. The
project is not on-the-web, so we have the fat client with rich GUI.

Our EJB3 project is under development. IMHO, EJB3 is stable enough.

Yes, exactly.
For me it was a big problem to understand how the composite key concept works.
But it became clear after I generated some beans from the datbase structure
with the JAG product: http://jag.sourceforge.net.
I can recommend you to generate some examples and you will see the best way
I simply downgraded to jboss-4.0.4, where it works fine.

Hi!
I think you should use the composite key as an id in your daughter class, I
think it is so in EJB3 spec.
P.S. May the force be with you
