Hi,
I have the following finder
@ejb.finder signature="java.util.Collection

tx.merchantTimestamp < ?1
* AND tx.sc=0 AND tx.bankTimestamp
Check out Xdoclet for generation of jboss-specific deployment descriptors.

Hi,
I am using Jboss 3.2.6 with the SLQ92 Compiler and have the following
problem:
I have 3 CMP entity beans (A1,A2 and B) both A beans hava a
1-1 relationship to B (A1 1---1 B 1 --- 1 A2). I can create a new
instance of A1 and call b.set(a1), however the exact same call
failes if I create a ne
Arne,
you should really make yourself familiar with
the documentation of Jboss, it will help you understand
how ejb-selects are _different_ from ejb-finder methods.
They ARE used to retrieve only a single field of
an entity bean. You also should take the time
and read the chapter about load-sets
I have a similar problem. I have 3 Beans A1,A2 and B.
both A1 and A2 have a 1-1 relationship to B. B
has a 1-1 Relationship to both A1 and A2.
If I create a instance of B and call b-setA1(A1), everything
works, whereas b.setA2(A2) doesnt work. The Relationships
are defined identical. I get the fol
Well, just forget the WHERE clause and you will get
the names of all customers. Anohter possibillity is to define
load-sets that correspond with the Xdoclet-defined value-objects.
(You can define more than one VO for an EB).

What you migth want are EJB-Selects, they allow
you to do something like
SELECT c.name FROM Customer AS c WHERE c.id=?1
EJB-Selects are descibed in the JBoss dokumentation
and are supported by special XDoclet-Tags.

I tried 3.2.6 and the Exception disappeared. But the query still gives
incorrect results (or at least unexpected results, maybe I am thinking
in the wrong way)
The SQL executed under 3.2.6 is:
SELECT DISTINCT t0_m.id FROM Merchant t0_m, MerchantPartnerContract
t1_m_merchantPartnerContract WHERE
I set logging to debug and the generated SQL is
Executing SQL: SELECT DISTINCT t0_m.id FROM Merchant t0_m WHERE
(t1_m_merchantPartnerContract.id IS NULL)
which doesn't look ok to me...

If I understand your setup correctly, you are
using the enity-beans remote interface, this
is usually not a good application design. Instead,
you should use a session bean in the same container as
a facade to the enity bean.

if you are using XDoclet, take a look at

hi,
What is the expected locking behaviour of ejbSelect methods ?
eg I have a bean called Merchant, if I use an ejbSelectAllMerchantIds
method via an ejbHomeGetAllMerchantIds, would this lock
all merchant EntityBeans as findAll() would do ?

The String consists of the characters [0-9]and[A-Z].
