Hi,
I have found a work-around for the differed (defered) inserts imposed
from JBOSS in a REQUESTS_NEW-CMT context:
...
// beans created and PK generated from DB (id-seq) [every bean
// have the "id" Integer-pk-prop]
ABean oABean = new ABean();
BBean oBBean = null;
CBean oCBean = null;
m_oEM.pe
Hi,
when I call and oABean.getBBeans(), on an ABean loaded from DB,
I obtain a "null" Set [on DB exist a C-record which link loaded
A-record with B-records]. Any Idea?
package test.ejb.entity;
import java.util.*;
import javax.persistence.*;
import javax.ejb.*;
@Entity
@Inheritance
@Table(name=
Hi,
I need to force the use of "CMTTransactionFactory" in an EJB app.

Thanks for your reply.
I putted this line:
@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
before stateless-session-bean method which execute
the INSERTs/SELECT. But after running code I have
obtained the same result. :(

Hi,
I have a small test-code (on JBOSS 4.0.4RC1) which execute this actions:
1) create an ABean (persistenced on DB)
2) create an BBean (whith an idA() prop) (persistenced on DB)
3) create an CBean (whith an idA() and idB() props) (persistenced on DB)
4) I excute an ABean.getBBeans() on the bean
Yes, my DB (postgres 7.4) support seq-tbl.
In fact, when I move id-specs from IdEntityBean
in every Bean it works perfectly ... :(
Note: I use JBOSS 4-0-4RC1
TIA

Deploy your shared components in
/default/ dir packed in a .JAR (NOT .EAR)
files.
.JAR it's shared by classloader.
