OC4J and OC4J in Oracle AS

Question

hi all,
i'm developing an enterprise application with netbeans 5.5.1. this application contains two modules: a web module and an ejb 3.0 module. i configured netbeans to deploy the application to OC4J standalone, and it works fine.
finally i build the application to obtain a .ear file: this .ear contains a .war file for the web application and a .jar file for the ejb module. When i try to deploy the .ear file to the oc4j into the oracle AS i've got some problems.
the OC4J standalone is the 10.1.3.2 version and the Oracle As is the 10.1.3.
there is difference between the two containers? or maybe i'm wrong in something?
The application server give me this error:
"Caricamento dell'archivio non riuscito. File di archivio non valido: Prefisso spazio di nomi 'oc4j' utilizzato ma non dichiarato."
in english: "archive loading failure. Archive file not valid: namespace prefix 'oc4j' used but not declared".
I readed in an forum that there isn't difference with the two containers (difference in the deployment), and if i develop and deploy an application to OC4J standalone, then i also deploy the same application to OC4J into oracle AS,
Someone could help me?
Thanks
Bye

Answer 1

ok, i resolve the problem:
during the creation of the enterprise application, netbeans automatically creates 3 configuration files: orion-application.xml (for the enterprise app), orion-web.xml (for the web module) and orion-ejb-ref.xml (for the ejb module). for the OC4J standalone the files are ok, but not for the OC4J in the application server. the OC4J in the AS doesn't need the the orion configuration files becouse it creates itself the files. so i delete the file, and create the .ear archive for the deployment.
If i have only Session Bean int the ejb module, all works fine, but if i add "Entity class from database" the deployment to the OC4J in the AS fails with this error:
in italian: Descrizione eccezione: Nessuna chiave primaria specificala per la classe di entità [class ejb.Dispositivi]. Deve definire un @Id, @EmbeddedId o una @IdClass.
in english: exception description: no one primary keys defined for the class ejb.Dispositivi. need to define @Id, @EmbeddedId or @IdClass
but my class ejb.Dispositivi was automatically created with an @Id annotation. my entity class is:
package ejb;

@Override
public int hashCode() {
int hash = 0;
hash += (this.idProgrDisp != null ? this.idProgrDisp.hashCode() : 0);
return hash;
@Override
public boolean equals(Object object) {
// TODO: Warning - this method won't work in the case the id fields are not set
if (!(object instanceof Dispositivi)) {
return false;
Dispositivi other = (Dispositivi)object;
if (this.idProgrDisp != other.idProgrDisp && (this.idProgrDisp == null || !this.idProgrDisp.equals(other.idProgrDisp))) return false;
return true;
@Override
public String toString() {
return "ejb.Dispositivi[idProgrDisp=" + idProgrDisp + "]";
any ideas?
Could someone help me?
Sorry for the english...
