Default JoinColumn name

[treespace]

I am getting frustrated in my attempt to use default names since I don't know what they are and cannot find a reference. Table and column names were changed from underscores to camel-case so no problem there: what you see is what you get. My relations, however, are another story.

What is the default join column from a book to its category? I think it's CATEGORY_ID. Where can I see in black-and-white (or suitable color:) what the default naming rules are? Since I have control of the schema I want to leverage defaults as much as is practical.

class Category
{
 ...
 @Id @GeneratedValue(strategy = GenerationType.AUTO) public long getId()...

 @OneToMany(mappedBy = "category") public List<Books> getBooks()...
 ...
}

class Book
{
 ...
 @Id @GeneratedValue(strategy = GenerationType.AUTO) public long getId()...

 @ManyToOne public Category getCategory()...
 ...
}

right this is category_id
This is written in the EJB3 spec (the pdf named persistence). Ask the expert group if you want a colored version ;-)

Thanks Emmanual. I found the specification sections you are referring to:

2.1.8.4.0
2.1.8.5.1
2.1.8.5.2

BTW, nice introduction here for anybody else wading (plunging in fact) in to EJB 3.0 as I am:
