Проверете дали сте задали правилно всички двупосочни връзки (между вашия обект com.model.Product и други обекти, свързани с него).

Например, ако имаше много-1 връзка от Product до Manufacturer, ще имате нещо като:

Product product = new Product();
product.setId(1);

Manufacturer manufacturer = new Manufacturer ();
manufacturer.setId(123);
product.setManufacturer(manufacturer); // set Many-1 side of relationship

Set<Product> products = new HashSet<Product>();
products.add(product);
manufacturer.setProducts(products); // set 1-Many side of relationship

Преди да вмъкнете, проверете вашите hbm файлове, може да има някакъв каскаден проблем (set cascade=all).
