HTTP Status 500 - Request processing failed; nested exception is Exception [EclipseLink-4002] - jpa

Question

I'am working with JPA eclipselink at the moment and like to connect to my Database with Eclipselink
I have some classes for de Tables in My database and a Query to get my Entries:
final Query query = entityManager.createQuery("SELECT q FROM FDC_DBCHANGE q ORDER BY q.CHANGE_ID");
I made some classes for my tables:
FDC_DBCHANGE
package com.bechtle.dbchanges.model;
import java.util.ArrayList;
import java.util.List;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.OneToMany;
#Entity
public class FDC_DBCHANGE {
#Id
#GeneratedValue(strategy = GenerationType.TABLE)
private long CHANGE_ID;
private String CHANGE_NAME;
private String CHANGE_DATE;
private int CHANGE_NUMBER;
#OneToMany(mappedBy = "FDC_DBCHANGE")
private final List<FDC_EXECUTED> checkBoxes = new ArrayList<FDC_EXECUTED>();
public String getChangeName() {
return CHANGE_NAME;
}
public void setChangeName(final String pChangeName) {
CHANGE_NAME = pChangeName;
}
public String getChangeDate() {
return CHANGE_DATE;
}
public void setChangeDate(final String pChangeDate) {
CHANGE_DATE = pChangeDate;
}
public int getChangeNumber() {
return CHANGE_NUMBER;
}
public void setChangeNumber(final int pChangeNumber) {
CHANGE_NUMBER = pChangeNumber;
}
public List<FDC_EXECUTED> getCheckBoxes() {
return checkBoxes;
}
#Override
public String toString() {
return "FDC_DBCHANGE [CHANGE_NAME=" + CHANGE_NAME + ", CHANGE_DATE="
+ CHANGE_DATE + "CHANGE_NUMBER=" + CHANGE_NUMBER + "]";
}
}
FDC_EXECUTED
package com.bechtle.dbchanges.model;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.OneToOne;
#Entity
public class FDC_EXECUTED {
#Id
#GeneratedValue(strategy = GenerationType.TABLE)
private int ENTRY_ID;
private FDC_DBCHANGE FDC_DBCHANGE;
private FDC_SYSTEM FDC_SYSTEM;
#OneToOne
#JoinColumn
public FDC_DBCHANGE getDbChange() {
return FDC_DBCHANGE;
}
public void setDbChange(final FDC_DBCHANGE pDbChange) {
FDC_DBCHANGE = pDbChange;
}
#OneToOne
#JoinColumn
public FDC_SYSTEM getSystem() {
return FDC_SYSTEM;
}
public void setSystem(final FDC_SYSTEM pSystem) {
FDC_SYSTEM = pSystem;
}
}
and FDC_SYSTEM
package com.bechtle.dbchanges.model;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.OneToMany;
#Entity
public class FDC_SYSTEM {
#Id
#GeneratedValue(strategy = GenerationType.TABLE)
private int SYSTEM_ID;
private String NAME;
private FDC_EXECUTED fdcexecuted;
public String getName() {
return NAME;
}
public void setName(final String pName) {
NAME = pName;
}
#OneToMany(mappedBy = "FED_SYSTEM")
public FDC_EXECUTED getExecuted() {
return fdcexecuted;
}
public void setExecuted(final FDC_EXECUTED pExecuted) {
fdcexecuted = pExecuted;
}
}
When I run it on my Tomcat there is this Exception:
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.5.0.v20130507-3faac2b): org.eclipse.persistence.exceptions.DatabaseException

Eclipselink tries to run the SQL Statement SELECT ENTRY_ID, FDC_DBCHANGE_CHANGE_ID, FDC_SYSTEM_SYSTEM_ID FROM FDC_EXECUTED WHERE (FDC_DBCHANGE_CHANGE_ID = ?)
instead of SELECT ENTRY_ID, CHANGE_ID, SYSTEM_ID FROM FDC_EXECUTED WHERE (CHANGE_ID = ?)
I don't konw why...
I hope someone can help me and sorry for my bad english...

Ok, problem solved, its cause Eclipselink needs an OID I have no acces to, that was the problem...
