I have a class with a composite PK that i'm using a separate PK class to implement. Seems to be an issue within XDoclet, but i'm not sure. Maybe somebody can catch my dumb error or otherwise move me in the right direction.

Role.java
package com.cimconsultants.STACS.hibernate;
import com.cimconsultants.STACS.hibernate.compositeKeys.RolePK;

/**
* Represents a Role from the database
*
* @hibernate.class table="UserRoles"
*
* @author Jason L. van Brackel
* @version 1.0
*/
public class Role {

private RolePK pk = null;
private String roleGroup = null;

public Role() {}

/**
* Return the Primary Key
*
* @hibernate.id generator-class = "assigned"
*
* @author Jason L. van Brackel
* @return String roleGroup
**/
public RolePK getPrimaryKey() {
if(pk == null) {
pk = new RolePK();
}
return pk;
}

/**
* Sets the roleGroup for this object
*
* @author Jason L. van Brackel
* @param String roleGrop
**/
public void setPrimaryKey(RolePK primaryKey) {
pk = primaryKey;
}



/**
* Return the Role Group (Roles)
*
* @hibernate.property column = "RoleGroup"
*
* @author Jason L. van Brackel
* @return String roleGroup
**/
public String getRoleGroup() {
return roleGroup;
}

/**
* Sets the roleGroup for this object
*
* @author Jason L. van Brackel
* @param String roleGrop
**/
public void setRoleGroup(String roleGroup) {
this.roleGroup = roleGroup;
}
}


RolePK.java

package com.cimconsultants.STACS.hibernate.compositeKeys;

import java.io.Serializable;

/**
* @author Jason L. van Brackel
*/
public class RolePK implements Serializable {
private String username;
private String role;

/**
* @hibernate.property column = "username"
* type = "string"
* not-null = "true"
* @author Jason
*/
public String getUsername() {
return username;
}

public void setUsername(String username) {
this.username = username;
}

/**
* @hibernate.property column = "roles"
* type = "string"
* not-null = "true"
*
* @author Jason
*/
public String getRole() {
return role;
}

public void setRole(String role) {
this.role = role;
}

public int hashCode() {
return this.hashCode();
}
}

You must override both the equals() method and the hashCode() method within your composite key class (RolePK)
