I got the same exception.
nested exception is: <0|false|0.9.7>
org.apache.openjpa.persistence.PersistenceException: The id type "class
com.werner.accounting.model.PeoplesoftSegmentId" specfied by persistent type
"class com.werner.accounting.model.PeoplesoftSegmentEntity" does not have a
public string or class + string constructor
ID Class is:
public class PeoplesoftSegmentId implements Serializable {
public String _businessUnit;
public String _vasTourId;
/** Creates a new instance of PeoplesoftSegmentId */
public PeoplesoftSegmentId() {
}
@Override
public int hashCode() {
int hash = 0;
hash += (this._businessUnit != null ?
this._businessUnit.hashCode() : 0);
hash += (this._vasTourId != null ? this._vasTourId.hashCode() :
0);
return hash;
}
@Override
public boolean equals(Object object) {
if(!(object instanceof PeoplesoftSegmentId)) {
return false;
}
PeoplesoftSegmentId other = (PeoplesoftSegmentId)object;
if(this._businessUnit != other._businessUnit
&& (this._businessUnit == null ||
!this._businessUnit.equals(other._businessUnit)))
return false;
if(this._vasTourId != other._vasTourId
&& (this._vasTourId == null ||
!this._vasTourId.equals(other._vasTourId)))
return false;
return true;
}
public String toString() {
return _businessUnit + ":" + _vasTourId;
}
}
Entity Class is:
@Entity
@IdClass(PeoplesoftSegmentId.class)
public class PeoplesoftSegmentEntity implements Serializable {
@Id
private String _businessUnit;
@Id
private String _vasTourId;
...
Thanks
