One to many mapping problem

[Predrag Ristic]

I have one to many mapping between Role and RoleFunctions but getRoleFunctions() method doesn't return anything.Can anyone tell me why?Here are the classes:

Role.java

package com.spinnaker.pedja;

import java.io.Serializable;
import java.util.ArrayList;
import java.util.Collection;

import javax.persistence.*;
import static javax.persistence.FetchType.EAGER;

@Entity
@Table(name = "role", schema = "edukacija")
public class Role implements Serializable {

	@Id
	@Column(name = "roleId")
	private int roleId;

	@Column(name = "role_name")
	private String roleName;

	public String getRoleName() {
		return roleName;
	}

	public void setRoleName(String roleName) {
		this.roleName = roleName;
	}

	@OneToMany(mappedBy = "role", fetch = EAGER, targetEntity = RoleFunctions.class)
	private Collection<RoleFunctions> roleFunctions = new ArrayList<RoleFunctions>();

	public int getRoleId() {
		return roleId;
	}

	public void setRoleId(int roleId) {
		this.roleId = roleId;
	}

	public Collection<RoleFunctions> getRoleFunctions() {
		return roleFunctions;
	}

	public void setRoleFunctions(Collection<RoleFunctions> roleFunctions) {
		this.roleFunctions = roleFunctions;
	}

}

RoleFunctions.java

package com.spinnaker.pedja;

import java.io.Serializable;

import javax.persistence.*;
import static javax.persistence.FetchType.EAGER;

@Entity
@Table(name = "role_functions")
public class RoleFunctions implements Serializable {

	@EmbeddedId
	private RoleFunctionsPk roleFunctionsPk;

	// @Column(name = "role_id", insertable = false, updatable = false)
	// private int roleId;

	@ManyToOne(fetch=EAGER)
	@JoinColumn(name="roleId", insertable = false, updatable = false)
	private Role role;

	public RoleFunctionsPk getRoleFunctionsPk() {
		return roleFunctionsPk;
	}

	public void setRoleFunctionsPk(RoleFunctionsPk roleFunctionsPk) {
		this.roleFunctionsPk = roleFunctionsPk;
	}

	// public int getRoleId() {
	// return roleId;
	// }
	//
	// public void setRoleId(int roleId) {
	// this.roleId = roleId;
	// }

	public Role getRole() {
		return role;
	}

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

}

RoleFunctonsPk.java

package com.spinnaker.pedja;

import java.io.*;

import javax.persistence.*;

@Embeddable
public class RoleFunctionsPk implements Serializable {

	/**
	 * 
	 */
	private static final long serialVersionUID = -4381904450375257793L;

	@Column(name = "roleId", insertable = false, updatable = false)
	private int roleId;

	@Column(name = "role_function", insertable = false, updatable = false)
	private String roleFunction;

	public int getRoleId() {
		return roleId;
	}

	public void setRoleId(int roleId) {
		this.roleId = roleId;
	}

	public String getRoleFunction() {
		return roleFunction;
	}

	public void setRoleFunction(String roleFunction) {
		this.roleFunction = roleFunction;
	}

	@Override
	public boolean equals(Object o) {
		if (o == this) {
			return true;
		}
		if (!(o instanceof RoleFunctionsPk)) {
			return false;
		}
		RoleFunctionsPk other = (RoleFunctionsPk) o;
		return (this.roleId == other.roleId && this.roleFunction
				.equals(other.roleFunction));
	}

	@Override
	public int hashCode() {
		final int prime = 31;
		int hash = 17;
		hash = hash * prime + this.roleId;
		hash = hash * prime + this.roleId;
		return hash;
	}
}

Is it returning null, or is it returning an empty list, or is it throwing an exception? Are there actually associated objects in the database?
