Hibernate error, possibly with DTD declaration

Question

Our project use\'s Hibernate\'s programmatic Configuration to set up our SessionFactory and such. I just migrated us from version 3 to version 4 of Hibernate. N

Answer 1

I also migrate from hibernate 3 to 4 ,

For hibernate.cfg.xml file i use following DTD

For mapping file i use follwing DTD:

PUBLIC "-//Hibernate/Hibernate Mapping DTD//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

If i change dtd it gives exception because hibernate 4 use xsd instead of dtd. Hibrenate Jira of migrating dtd to xsd

So you have to use xsd file instead of dtd.
