does jboss come with an email server? My guess is not, but would like
to see if anyone can confirm.
Thanks,

Hi list,
While iterating through a Collection of children in a one-to-many CMR that I
obtained by a child bean finder method, I use the child's CMR accessor to get
a reference to the parent entity, and then get some of the parent fields.
However, if the parent is non-existent (these data are fro

I solved my problem. Stupid mistake, which was what I thought it would be:
I had in the dd set to 'Bean' rather than 'Container'. I
must've copy-n-pasted some of the dd content from another session bean and
forgot to change it.
I guess that's what I deserve for not using xdoclet on this p

My life became _blissful_ about a month ago when I ditched entity beans
and started using Hibernate for persistence. My data model objects are
all pure java beans which I can 1) pass out of the EJB system and 2)
cache anywhere I want, for however long I want, in a clustered
environment.

May applications happily use CMP today, and
i think that maybe using a read-ahead configuration for cmr could turn
CMP usable, hence the cause of the slowness (IMHO) is the great number
of selects as you navigate through each BEAN.

Hello!
I see in standardjboss.xml some pool settings to help control how many
MDBs are instantiated. What is the difference between the
container-invoker-conf/MaximumSize (default 15) and the
container-pool-conf/MaximumSize (default 100)?
Also, is there a way to control this on a per MDB basi

Yeah, that helped a lot. (duh!)

JBoss is being used in production everywhere. I've been at 6 sites myself
over the past year. IMHO and experience, entity beans are not the right
choice if you're doing complex reporting. A handmade query cache with
direct JDBC will always be faster. Besides, EJB QL doesn't have Group By.

I honestly wish you the best of luck with your project. There are some

people come to this conclusion way to early, but I bet you spent a long

Do I need to create this file? Where should I put it?

Hi, Justin,
I'm seeing something almost identical in a unit test I have. My code is
slightly different than yours, but not by much. Basically, I create add
an object to another (parent) object and when I try to fetch it by
primary key and then ask for the child collection I get the same error.
JBoss is losing credibility in our firm due to this performance problem as
well as the issues i've noted about JMS performance.
If anyone cares whether JBoss is actually used in the production
environment, the team might consider investing time in making it perform
well.

The J2EE specifications contain lots of information about
concurrency-related issues.
Perhaps you have a more specific question?

Hello Georg,
Do you mean that your slowness problem occurs when accessing the collection
*even* in mono-threaded behaviour? If I understand your scenario, you have
something like this:
- a web page that display the content of 4000 entity beans (either directly
or using a SLSB)
- the entity bean
The behaviour imposed by the pessimistic locking violates the principle
of "least surprise" for most Jboss users, I guess. That's the reason why
you have to answer these questions a million times.
If I am using all the EJB/J2EE/CMP stuff, I expect that I do not have to
care about concurrency, tra
