Question

I am wondering how to write the model, hbm.xml for table

Company
-------
id(PK)
name
address
typeid(fk)

Type
----
id(PK)
type

class Company(){
int id;
String name;
String address;
Type type;
}

class Type(){
int id;
String type;
}

(with get/set methods)

How to write the hbm?

I am using the hibernate 3.x.

Answer 1

Can you have multiple companies of the same type?
Don’t you really want a many to one relationship?

How about something like this (adapted from the Hibernate docs from here):

<class name="Company" table="company">
    <id name="id" column="id">
    ...
    </id>
    ....
    <many-to-one name="type" 
        class="Type"
        column="typeid" 
        not-null="true"/>
</class>

<class name="Type">
    <id name="id" column="id">
        ...
    </id>
</class>
