Insert failing

Question

I have a JDO class which has a composite key
package com.yodlee.yde.persistence.configuration;
import java.util.List;
public class ConfigSession {
private String id;
private Long configId;
private String aSession;
private Long length;
private Long lastAccess;
private java.util.Date createDate;
private Long source;
private String sessionData;
private Long dbSessionId;
private Config configOfConfigId;
public ConfigSession() {
public String getId() {
return id;
public void setId(String id) {
this.id = id;
public Long getConfigId() {
return configId;
public void setConfigId(Long configId) {
this.configId = configId;
public String getASession() {
return aSession;
public void setASession(String aSession) {
this.aSession = aSession;
public Long getLength() {
return length;
public void setLength(Long length) {
this.length = length;
public Long getLastAccess() {
return lastAccess;
public void setLastAccess(Long lastAccess) {
this.lastAccess = lastAccess;
public java.util.Date getCreateDate() {
return createDate;
public void setCreateDate(java.util.Date createDate) {
this.createDate = createDate;
public Long getSource() {
return source;
public void setSource(Long source) {
this.source = source;
public String getSessionData() {
return sessionData;
public void setSessionData(String sessionData) {
this.sessionData = sessionData;
public Long getDbSessionId() {
return dbSessionId;
public void setDbSessionId(Long dbSessionId) {
this.dbSessionId = dbSessionId;
public Config getConfigOfConfigId() {
return configOfConfigId;
public void setConfigOfConfigId(Config configOfConfigId) {
this.configOfConfigId = configOfConfigId;
here is the package definition for it
<class name="ConfigSession">
<extension vendor-name="tt" key="table" value="COB_SESSIONS"/>
<extension vendor-name="tt" key="pk-column" value="ID"/>
<extension vendor-name="tt" key="pk-column" value="COBRAND_ID"/>

</field>
<field name="createDate">

value="CREATE_DATE"/>
</field>
<field name="source">
<extension vendor-name="tt" key="data-column"
value="SOURCE"/>
</field>
<field name="sessionData">
<extension vendor-name="tt" key="data-column"
value="SESSION_DATA"/>
</field>
<field name="dbSessionId">
<extension vendor-name="tt" key="data-column"
value="DB_SESSION_ID"/>
</field>
<field name="configOfConfigId">
<extension vendor-name="tt" key="data-column"
value="COBRAND_ID"/>
</field>
</class>
when i add a new object instance.. i.e an insert into the table, i get this
error.
javax.jdo.JDODataStoreException: [SQL=INSERT INTO COB_SESSIONS (COBRAND_ID,
SESSION_DATA, ID, DB_SESSION_ID, LAST_ACCESS, LENGTH, COBRAND_ID,

Obviously, the field cobrand_id is repeating.
Can you help me out with this?

Answer 1

It works. I changed the metadata.
But, on an inverse collection, The JDO returns an error. there seems to be a
basic error in defining the referencing. Can somebody help me out here?
javax.jdo.JDODataStoreException: [SQL=SELECT

Actually your problem is that you're not telling Kodo that you're using
application identity. The default behavior for persistent classes is to
use datastore identity, meaning the JDO implementation generates its own
unique id for each instance, one that is independent of the values of the
fields of your object.
In your case, the primary key is composed of 2 fields that exist in your
object; hence you want to use application identity. This involves
several changes to your JDO metadata. See the relevant jdo and user
guide documentation for details.
It may be possible to 'hack' it and use datastore identity but map the
primary key column to a field of your class, but this is not recommended,
and in any case will not work for compound primary keys.
