There is nothing special in relation @OneToMany @ManyToOne (Hibernate tool generated mappings
for two tables - In database there is relation on this two tables):

First class has this property:

	private Set<yyy> yyy= new HashSet<yyy>(0);

	private Set<CustomerAccount> customerAccounts = new HashSet<CustomerAccount>(0);
	@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy = "xxx")
	public Set<yyy> getYyys() {
		return this.yyy;
	}

	public void setYys(Set<yyy> yyys) {
		this.yyys = yyy;
	}

Second class has this propertie:

	private Xxx xxx;

	@ManyToOne(fetch = FetchType.LAZY)
	@JoinColumns( { @JoinColumn(name = "aaa", referencedColumnName = "aaa"),
			@JoinColumn(name = "bbb", referencedColumnName = "bbb") })
	public Customer getXxx() {
		return this.xxx;
	}

	public void setXxx(XXX xxx) {
		this.xxx= xxx;
	}
