I have the following two database tables:

Create Cached Table Users (
Id Integer Generated By Default as Identity (Start With 1, Increment By 1) Primary Key,
Username VarChar(16) Default '' Not Null
);

Create Cached Table UserLogins (
Id Integer Generated By Default as Identity (Start With 1, Increment By 1) Primary Key,
UserId Integer Default 0 Not Null,
LoginTimestamp Timestamp Default Now Not Null,
IP VarChar(16) Default '' Not Null
);

I have the POJOs User and UserLogin.

I have the following Hibernate mappings:

<hibernate-mapping>
<class name="myapp.domain.entities.User" table="Users">
<id name="id" column="Id" access="field"><generator class="identity" /></id>
<property name="username" column="Username" not-null="true" length="16" />
</class>
</hibernate-mapping>

<hibernate-mapping>
<class name="myapp.domain.entities.UserLogin" table="UserLogins">
<id name="id" column="Id" access="field"><generator class="identity" /></id>
<property name="userId" column="UserId" not-null="true" />
<property name="loginTimestamp" column="LoginTimestamp" not-null="true" />
<property name="ip" column="IP" not-null="true" length="16" />
</hibernate-mapping>

Each User entity can reference 0..n UserLogin entities. Each UserLogin entity is referenced by exactly 1 User entity. What changes do I need to make to my xml mappings and my POJOs to configure a one-to-many relationship in Hibernate?

Cheers.
