in my ejb i have such a construct...
private long productsId;
private List categories;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "products_id")
public long getProductsId() {
return productsId;
}
public void setProductsId(long productsId) {
this.productsId = productsId;
}
@ManyToMany
@JoinTable(name = "products_categories", joinColumns = @JoinColumn(name = "products_id", referencedColumnName = "products_id"), inverseJoinColumns = @JoinColumn(name = "categories_id", referencedColumnName = "categories_id"))
public List getCategories() {
return categories;
}
public void setCategories(List categories) {
this.categories = categories;
}
i get a list with content from db...
but if i want to access the list... :-(
Caused by: org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role:... , no session or session was closed
what should i change...
