Issue

I have a pojo named Incident,

@Entity
@Inheritance(strategy = InheritanceType,JOINED)
@Table(name = "TBLINCIDENT")@EntityListeners(IncidentListener,class)
@Indexed@NamedQuery(name = "Incident,changeRestrictedStatus", query = "Update Incident set bsar = :status where id = :incidentId")
public class Incident extends BaseDataType implements Serializable {@Column(name = "BSAR")
public Boolean getSar()
{
    return this,sar;
}

I have another pojo which extends this pojo named AccidentReport

@Entity
@Table(name = "TBLACCIDENTREPORT")
public class AccidentReport extends Incident{

Using the InheritanceType,JOINED will cause the jboss server to raise the following error on start up,

Error installing to Start: name=persistence,unit:unitName=#care state=Create
