Hello,

I'm trying to persist some entities, cascading persist and merge, using a JBoss AS6.0.0.FInal server

This is an excerpt of the entities structure:

@Entity
@Inheritance(strategy = InheritanceType.JOINED)
public abstract class Solicitud {
...
    @ManyToOne(optional = false, targetEntity = Solicitante.class, cascade = { PERSIST, MERGE})
    public Contribuyente getContribuyente() {
        return this.contribuyente;
    }
}

@Entity
public class SolicitudEmision extends Solicitud {
...
     @OneToOne(optional = false, targetEntity = SolicitudClaveAcceso.class, cascade = { PERSIST, MERGE })
    public SolicitudClaves getSolicitudClavesContingencia() {
        return this.solicitudClavesContingencia;
    }

    @ManyToMany(targetEntity = TipoComprobante.class, cascade = {PERSIST, MERGE})
    public List<TipoDocumentoElectronico> getTipoComprobantesSolicitados() {
        return comprobantesSolicitados;
    }
}

All relationships are unidirectional. The failing test declares a SolicitudEmision object and adds on it an instance of the cascaded types. All this records are to be inserted. Finally it uses invokes merge() in the EntityManager and passes the SolicitudEmision object.

The thrown exception is as follows

javax.ejb.EJBTransactionRolledbackException: Transaction rolled back
...
Caused by: javax.transaction.RollbackException: ARJUNA-16053 Could not commit transaction.

    at org.jboss.ejb3.tx2.impl.CMTTxInterceptor.endTransaction(CMTTxInterceptor.java:82)
    ... 132 more

Running on a JBoss AS6.1.0.Final server causes the exact same error.

What might be causing this error?

Thanks in advance
