Problem CMR ejb 3.0 with JDeveloper Preview 3

Question

I created 2 entity beans (using drag and drop from JDeveloper 10.1.3 preview 3)
for 2 tables INCIDENTS and ENVINCIDENTS ENVINCIDENTS has a foreign key INCIDENTS_ID referring INCIDENTS.ID.I get the following error when I created ejb 3.0 beans and deployed them.
Exception Description: Multiple writable mappings exist for the field [ENVINCIDE
NTS.INCIDENTS_ID]. Only one may be defined as writable, all others must be spec
ified read-only.
If i remove the relationships they work fine. Also they work fine if I create ejb 2.1
the culprit bean is below:
@Id
@Column(name="INCIDENTS_ID", primaryKey=true, nullable=false)
public Long getIncidentsId() {
return incidentsId;
public void setIncidentsId(Long incidentsId) {
this.incidentsId = incidentsId;
@Id
@ManyToOne(targetEntity="model.Incidents")
@JoinColumn(name="ENVINCIDENTS.INCIDENTS_ID", referencedColumnName="INCIDENTS.ID",insertable=false, updatable=false)
public Incidents getIncidents() {
return incidents;
public void setIncidents(Incidents incidents) {
this.incidents = incidents;

Hi HERBOLY ,
To be able to run the clien you must run first the facade bean then try to run your client.
Hope this will help you .
