Hibernateコレクションのマッピングにほとんど迷いません。Eclipse Hibernateパースペクティブに永続性構成を追加しようとすると、次のようになります。

Invalid ORM mapping file.
Error parsing XML (line14 : column 16): The content of element type "list" must match "(meta*,subselect?,cache?,synchronize*,comment?,key,(index|list-index),(element|one-to-many|many-to-many|composite-element|many-to-any),loader?,sql-insert?,sql-update?,sql-delete?,sql-delete-all?,filter*)".
Error parsing XML (line17 : column 15): The content of element type "map" must match "(meta*,subselect?,cache?,synchronize*,comment?,key,(map-key|composite-map-key|map-key-many-to-many|index|composite-index|index-many-to-many|index-many-to-any),(element|one-to-many|many-to-many|composite-element|many-to-any),loader?,sql-insert?,sql-update?,sql-delete?,sql-delete-all?,filter*)".

実際のマッピング構成は次のとおりです。

順序は具体的です(そしてエラーメッセージであなたに与えられます)。これは休止状態のものではなく、XMLスキーマのものです。

したがって、タグの順序を正しくしてください。たとえば、<list-index>は<1対多>の前にある必要があります。

編集:すべてのテーブルが間違っているわけではありません。最初のものは大丈夫です。2番目のものには2つのエラーがあり、

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>
    <class name="core.User" table="user" schema="imdb">
        <id name="userId" type="java.lang.Integer">
            <column name="USER_ID" />
            <generator class="identity" />
        </id>   
        <property name="login" column="LOGIN" type="string" />          
        <property name="online" column="ONLINE" type="boolean" />   
        <property name="last_message" column="LAST_MESSAGE" type="string" />  
        <property name="newmessage" column="NEW_MESSAGE" type="boolean" />  
        <list name="sessions" inverse="true">
            <key column="USER_ID" not-null="true"/>
            <list-index column="USER_SESSION_NUMBER" />
            <one-to-many class="core.Session"/>          
        </list>   
        <many-to-one name="serverID" column="SERVER_ID" class="core.Server"/>
    </class>
</hibernate-mapping>

class = "core.User-の後に引用符がないため、3番目のものは間違っています。

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>
    <class name="core.Session" table="session" schema="imdb">
        <id name="sessionID" type="java.lang.Integer">
            <column name="SESSION_ID" />
            <generator class="identity" />
        </id>   
        <many-to-one name="serverID" column="SERVER_ID" class="core.Server"/>
        <many-to-one name="userID" column="USER_ID" class="core.User"/>
