I found during excercise of having two separeted EAR that I have to swithc the
CallByValue to 'true' in order to have ears work
I'm a little bit lost with this 'CallByValue'. My question is what exactly
CallByValue does and when.
1. When using local interfaces:
- passing is always by referenc
I've checked 3.2.7 - the same situation.
I think it is time to issue bug.

As triathlon98 says, it is similar in 4.0.2 so probably 3.2.7 also. And I have
100+ beans,
Could someone confirm if it is normal behaviour or bug or my wrong
configuration?!?
It really kills performance.

SQL in SessionBean is spagethi code (or at least anti-pattern). Use Entity Bean
for it.
Mapping for PostgreSQL is:
java.lang.Object
VARBINARY
BYTEA
Did you try such field in entity?
(I use String and TEXT for very long texts and works perfec
JBoss 3.2.6, default setting in standardjbosscmp-jdbc.xml, commit option A used.
I observed strange selects for two applications. There is relation A -> many B
(unidirectional).
a.getBs() gives select:
SELECT LOID FROM B WHERE (A_FK=?)
and now every entity B is access by fields, it gives:
SELECT
IMHO the method of setting fk field as nullable is the best and easiest
solution. See page before how to achieve it in XDoclet.

Sequence is specified for pk as follows:
my_sequence
it there any way to tell JBoss to create the sequence when ear deployed (as for
all tables, etc)?
I digged and I couldn't find how.
One can say: do it youselft is is just one sql: 'create sequence my_sequence'
Adrian, I don't undestand your possition.
I'm not 'lazy user', before making post I check forum and wiki for half a day.
And as you have seen I tried to debug and UNDERSTAND what is going on after
redeploying of DS.
Also several other people have seen my post - no answer, so seems that noone is

My situation is more annoying as I have to modify Java files as well to switch

Should I back 20 years and make some preprocessing (like C #define)? Horrible.
Should I do some postprocessing on descriptors? (a little bit better).

In fact I was thinking of EntityBean (instead of EJBObject) and only connection
in the server layers, never to the client of course.
There is often a need to have the connection (in server side layers) to do some
queries (fast line reader design pattern) or huge-updates. And currently I
don't s
Hi all,
I want to do some business checking in beforeCompletion. In order to do this I
have to get the db connection.
How to obtain the connection in easy portable way?
Till now I've seen: use JNDI + hardcoded name of datasource, lookup, get
datasource and getConnection.

Hi all,
Is there a way to tell the container (in declarative way) to make

If session bean(s) have big amount of business methods (> 100), it is extremely
boring and faultfull to put everywhere try catch { setRollbackOnly}.
So I would imagine that in descrip

I'm currently trying to properly build in authentication into application

2. some urls are accessed only with authorisation;
3. some are unauthorised;

Hi all,
I need to add some post actions after the deployment.
The best would be on the entity bean layer - when entity bean is deployed it launches
my hook (method). I need such a method to make some configuration in DB (create some
data) and launched only once (just after deployment)
If possible
Hi all,
How to write in EJB-QL the EXISTS statement in WHERE (like in SQL92)?
For now it seems to me that it is not in the EJB-QL spec and JBoss-QL as well.
More general observation, which probably most of you can share:
I've just started to be familiar wit JBoss and CMP and found that some very b
