[jboss-user] [EJB 3.0] - The problem of

[bairaulinter]

I have 3 entity beans, followings are the codes:

public class Product implements Serializable {
     ........
        @ManyToOne(cascade = CascadeType.ALL)
	@JoinColumn(name = "categoryID")
	public Category getCategory() {
		return category;
	}
	public void setCategory(Category cate) {
		this.category = cate;
	}
	
	@ManyToOne(cascade = CascadeType.ALL)
	@JoinColumn(name = "productOwner")
	public User getUser() {
		return user;
	}
	public void setUser(User u) {
		this.user = u;
	}
    .......
}

=============================================
public class User implements Serializable{
     .........
	@OneToMany(mappedBy = "user", cascade = CascadeType.ALL, fetch = FetchType.LAZY)
	public Collection getProducts() {
		return products;
	}
	public void setProducts(Collection pro) {
		this.products = pro;
	}
}

=============================================
public class Category implements Serializable {
   ..........
	@OneToMany(mappedBy = "category", cascade = CascadeType.ALL, fetch = FetchType.LAZY)
	@OrderBy(value = "productID ASC")
	public Collection getProducts() {
		return products;
	}
	public void setProducts(Collection pro) {
		this.products = pro;
	}
}

\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
Then, I want to insert a record into the database. First, the categoryID and   userID have been in the database! categoryID and userID are the foreign key of table: Product!

I don't know how to do it! Can you help me?
Thank you!
