Can't make Seam managed transactions work
Hi,
I try to run POJOs / JavaBeans Seam components on OpenEJB 3.0. For what I understood, I need to use Seam managed persistence context and Seam managed transactions and I sould have the same beahaviour as EJB3 session beans.
I could make Seam managed persistence context work thanks to Stuart Douglas help : http://www.seamframework.org/Community/SeammanagedPersistenceContextOnOpenEJB
Now I try to configure Seam managed transactions but I can't make it work.
The persistence.xml file is like this :
<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" version="1.0"> <persistence-unit name="t4Seam"> <provider>org.hibernate.ejb.HibernatePersistence</provider> <jta-data-source>java:/jdbc/t4Seam</jta-data-source> <mapping-file>META-INF/orm-utils.xml</mapping-file> <properties> <property name="hibernate.hbm2ddl.auto" value="update"/> <property name="hibernate.show_sql" value="false"/> </properties> </persistence-unit> </persistence>
In components.xml I added this :
<transaction:ejb-transaction />
And my Seam components are like this :
@Transactional(TransactionPropagationType.REQUIRED)
public class FileAppenderDaoBase
implements FileAppenderDao
{
@In
protected javax.persistence.EntityManager emanager;
...
}
My unit tests call Groovy scripts that call my Saem components. It used to work when my Seam components were EJB3 session beans. But now they are POJOs I have the following stack trace :

Anyone has an idea what happens ?
I have one more question about using both Seam components as EJB3 session beans or POJOs. I mean that a Seam EJB3 session bean could call a Seam POJO. Do these both components share persistence context (if I inject Seam managed persistence context of course) and transactions ?
Thanks in advance,
Olivier
