I am trying to set up a one-to-many relationship, but keep hitting a wall when I get the following error:
java.lang.NoClassDefFoundError: org/odmg/DCollection
...

Any help would be great!

My classes:
package com.ffic.hibernate_spoe;
import java.util.Set;
public class Insured {
private Long insdID;
private String insdNm;
private String insdBus;
private Set policies;

public String getInsdBus() {return insdBus;}
public Long getInsdID() {return insdID;}
public String getInsdNm() {return insdNm;}
public Set getPolicies() {return policies;}
public void setInsdBus(String string) {insdBus = string;}
public void setInsdID(Long long1) {insdID = long1;}
public void setInsdNm(String string) {insdNm = string;}
public void setPolicies(Set set) {policies = set;}
}

package com.ffic.hibernate_spoe;
import java.util.Date;
public class Policy {
private Long polID;
private String polNo;
private Long limits;
private Date poleffdt;
private Date polexpdt;
private Insured insured;

public Insured getInsured() {return insured;}
public Long getLimits() {return limits;}
public Date getPoleffdt() {return poleffdt;}
public Date getPolexpdt() {return polexpdt;}
public Long getPolID() {return polID;}
public String getPolNo() {return polNo;}
public void setInsured(Insured insured) {this.insured = insured;}
public void setLimits(Long long1) {limits = long1;}
public void setPoleffdt(Date date) {poleffdt = date;}
public void setPolexpdt(Date date) {polexpdt = date;}
public void setPolID(Long long1) {polID = long1;}
public void setPolNo(String string) {polNo = string;}

My DB2 Create Table script:
CREATE TABLE IMUN0D00.A_INSURED ("INSUREDID" BIGINT NOT NULL GENERATED ALWAYS AS IDENTITY (START WITH 0, INCREMENT BY 1, NO CACHE ) , "INSUREDNAME" CHARACTER (25) NOT NULL , "INSUREDBUS" CHARACTER (25) NOT NULL , PRIMARY KEY (INSUREDID) ) DATA CAPTURE NONE
CREATE TABLE IMUN0D00.A_POLICY ("POLICYID" BIGINT NOT NULL GENERATED ALWAYS AS IDENTITY (START WITH 0, INCREMENT BY 1, NO CACHE ) , "POLICYNO" CHARACTER (11) NOT NULL , "LIMITS" BIGINT NOT NULL , "EFFDATE" DATE NOT NULL , "EXPDATE" DATE NOT NULL , "INSUREDID" BIGINT NOT NULL , PRIMARY KEY (POLICYNO, POLICYID) , FOREIGN KEY (INSUREDID) REFERENCES IMUN0D00.A_INSURED (INSUREDID) ) DATA CAPTURE NONE

The class definition for an ODMG class could not be found. In other wirds, you need odmg.jar in your classpath.

You are missing the odmg.jar in your classpath. Take a look at the readme file in the lib directory of the hibernate distribution for a list of required jars.

Thanks!

It worked!

I tried to read the readme.txt in lib, but it is not very readable. Is it supposed to be opened via notepad?

everything but notepad can render it fine. Notepad is confused about unix end of line.
