Mapping file is not parsed

[czy11421]

I am using Spring 2.0.6 and Hibernate 3.0. But I always get error when it parses
<discriminator column="des" type="string" />


Here is my mapping file

<?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="data.User" table="mts_user" >
<cache usage="read-write"/>
<id name="userId" column="userId">
<generator class="increment"/>
</id>
<property name="userName"/>
<property name="active" type="java.lang.Boolean" />

<discriminator column="des" type="string" />

<subclass name="data.Employee" discriminator-value="EMPLOYEE">
<property name="salary" />
</subclass>

</class>

</hibernate-mapping>


The exception is


org.xml.sax.SAXParseException: The content of element type "class" must match "(meta*,subselect?,cache?,synchronize*,comment?,tup lizer*,(id|composite-id),discriminator?,natural-id?,(version|timestamp)?,(property|many-to-one|one-to-one|component|dynamic-component|properties|any|map|set|list|bag|idbag|ar ray|primitive-array)*,((join*,subclass*)|joined-subclass*|union-subclass*),loader?,sql-insert?,sql-update?,sql-delete?,filter*,resultset*,(query|sql-query)*)".

I guess it is the parser problem. I am using Dom4j-1.6 and JDK1.5, The IDE is Eclipse 3.2.
Thanks.

It isn't a parser problem, if you look closer at the error message it tells you that the structure of your xml isn't valid. If you take an even closer look it also tells you the structure that it should validate against. That tells you that your discriminator element must become after your ID element and before anything else.

Yes, you are right.

Thanks.

I'm using Spring 2.0.8 and Hibernate 3.2, and now I've got the same problem too, but I guess there is a little bit difference between czy11421's and mine.
I've put the <discriminator> after <id>, and the exception was still occurred.
could anyone help me solve this problem ?

hah~~I've solved by myself.
why did the expception occur is the <subclass> should've been placed after <property>..
