Hibernate issue with using http://www.hibernate.org/dtd [duplicate]

Question

I'm currently using http://hibernate.sourceforge.net as my namespace in my hibernate configuration files which gives me these warnings:

Recognized obsolete hibernate namespace http://hibernate.sourceforge.net/. Use namespace http://www.hibernate.org/dtd/ instead. Refer to Hibernate 3.6 Migration Guide!

So I tried switching hibernate.cfg.xml and all the other *.hbm.xml files to using http://www.hibernate.org/dtd. However then when I try to generate the code using hibernate tools in eclipse I get the following error message (code generation works fine with the other namespace):

org.hibernate.HibernateException: Could not parse configuration: C:\dev\workspace\DataLoad\hibernate.cfg.xml Could not parse configuration: C:\dev\workspace\DataLoad\hibernate.cfg.xml
org.dom4j.DocumentException: www.hibernate.org Nested exception: www.hibernate.org www.hibernate.org Nested exception: www.hibernate.org org.dom4j.DocumentException: www.hibernate.org Nested exception: www.hibernate.org www.hibernate.org Nested exception: www.hibernate.org

Here's my hibernate.cfg.xml:

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

We had also some problems parsing hibernate cfg files in last time. The root of the cause was that the hibernate site was unreachable. After some googling and debugging org.hibernate.util.DTDEntityResolver class, I realized that there is also another way, how to specify the DTD URL:

<!DOCTYPE hibernate-configuration SYSTEM
    "classpath://org/hibernate/hibernate-configuration-3.0.dtd">

This means that hibernate will load the DTD from classpath - it is usually included in hibernate jar in org/hibernate directory.

However, we use hibernate 3.5.6 - I don't hnow if this approach still works in the newer version - give it a try. The benefit of this is that you are completely independent on internet connection, proxies and so on.

In my case hibernate3.5.6 and some other jars are packed into a base jar names testbase.jar, when i give the mentioned answer my build is success but give file not found exception. If i give "classpath://testbaseorg/hibernate/hibernate-configuration-3.0.dtd" during build itself i am getting an error classpath is not a protocol

Check this migration guide: https://community.jboss.org/wiki/HibernateCoreMigrationGuide36

You have to change the dtd url to http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd
