JBO-30012 error
Hi,
I'm working with Oracle JDEV product version and oracle 9ias (oc4j release 2)
I've a problem with a BC4J application module.
I deploy my application.
I deploy my BC4J as an EJB session Module.
when i'm executing the following code, I have an error on the getVo function:
this error occurs from time to time.
public boolean etatChargement() {
boolean etat=false;
userAccess = new BC4J_access();
userAccess.openConnection();
ViewObject correlViewObj = userAccess.getVO("CorrelationView");
correlViewObj.executeQuery();
while(correlViewObj.hasNext()) {
Row correlView = correlViewObj.next();
if(correlView.getAttribute("EtatChargement")!=null)
if(correlView.getAttribute("EtatChargement").toString().equals("EC")) {
etat=true;
break;
}
}
if(!etat) {
Long data = new Long (this.m_idCorrelation);
correlViewObj.setWhereClause("Correlation.ID_CORRELATION="+new Number(data));
correlViewObj.executeQuery();
Row correlV= correlViewObj.next();
if (correlV.getAttribute("EtatChargement")==null)
this.m_etat=null;
else
this.m_etat=correlV.getAttribute("EtatChargement").toString();
correlV.setAttribute("EtatChargement","EC");
userAccess.commit();
}
correlViewObj.remove();
userAccess.closeConnection();
return etat;
}
