Hello,
I have trouble when trying to store objects with ejb3 entities. I follow the
trailer (http://trailblazer.demo.jboss.com/EJB3Trail/) which is a very good
support. However when I deploy my ear I have the following errors:
FATAL [PersistenceXmlLoader] ejb3essaiPerst JTA
and when I use the EntityManager to persist an object, an exception is throwned:
00:09:25,872 WARN [JDBCExceptionReporter] SQL Error: -22, SQLState: S0002
00:09:25,872 ERROR [JDBCExceptionReporter] Table not found in statement [insert
into t_tech (prenom, nom) values (?, ?)]
00:09:25,872 ERROR [AbstractFlushingEventListener] Could not synchronize
database state with session
org.hibernate.exception.SQLGrammarException: could not insert:
[fr.aulnette.essai.ejb3.entity.TechnicienBOBean]
at
org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:65)
at
org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:43)
[...]
Caused by: java.sql.SQLException: Table not found in statement [insert into
t_tech (prenom, nom) values (?, ?)]
at org.hsqldb.jdbc.Util.throwError(Unknown Source)
[...]
In fact the table creation doesn't appear anymore in the hsqldb log but I don't
know why.
The Entity bean code:
-------------------------
@Entity
@Table(name="t_tech")
public class TechnicienBOBean implements Serializable {
String nom;
String prenom;
//SiteBOBean site;
@Id
public String getNom() {
return nom;
}
public void setNom(String nom) {
this.nom = nom;
}
[...]
}
The Session Stateless bean code:
---------------------------------------
@Stateless
public class TechnicienBSBean implements TechnicienBSI, TechnicienRemoteBSI {
@PersistenceContext(unitName="ejb3essaiPerst")
protected EntityManager em;
public void storeTechnicienInDB(String nom, String prenom) {
TechnicienBOBean technicienEntity = new TechnicienBOBean();
technicienEntity.setNom(nom);
technicienEntity.setPrenom(prenom);
em.persist(technicienEntity);
}
[...]
}
The persistence.xml file is embedded into the META-INF directory of my ejb
findTechnicien-ejb.jar:
-------------------
<persistence-unit name="ejb3essaiPerst">
<jta-data-source>java:/DefaultDS</jta-data-source>
</persistence-unit>
The application.xml file is embedded into the META-INF directory of my ear:
-------------------
<display-name>findTechnicien</display-name>
findTechnicien-ejb.jar
Some help would be very appreciated because i have no more ideas.
thank you,
