Hi all,

I tried to use hbm2java to generate java classes from the hbm.xml file. I used the Cat.hbm.xml file coming with Quickstart example and got "Document root element is missing" error when running the hbm2java. I don't have any problem to run the example. Is anyone know what the problem is? Here is the xml.

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping
PUBLIC "-//Hibernate/Hibernate Mapping DTD//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">

<hibernate-mapping>

<class name="net.sf.hibernate.examples.quickstart.Cat" table="CAT">

<!-- A 32 hex character is our surrogate key. It's automatically
generated by Hibernate with the UUID pattern. -->
<id name="id" type="string" unsaved-value="null" >
<column name="CAT_ID" sql-type="char(32)" not-null="true"/>
<generator class="uuid.hex"/>
</id>

<!-- A cat has to have a name, but it shouldn' be too long. -->
<property name="name">
<column name="NAME" sql-type="varchar(16)" not-null="true"/>
</property>

<property name="sex"/>

<property name="weight"/>

</class>

</hibernate-mapping>

Thanks for every help!

Show the full stack trace please

It works when I use hbm2java.bat in Windows. Thanks!
