Using MySQL 5 and Eclipse 3.1, which I believe to be irrelevant. The application worked fine with Hibernate 3.0.

Have changed hibernate.cfg.xml to include two new Hibernate 3.1 elements shown below:

<property name="current_session_context_class">thread</property>

<!-- Disable the second-level cache -->
<property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>

Note the doctype continues to refer to Hibernate 3.0 - is this appropriate?

<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

Here is what I believe to be the relevant portion of the log, resulting from running the Ant task:

Thanks very much.

I guess you should post the entire hibernate.cfg.xml to clarify where the problem is.

Thanks for the reply.

Here is the entire file contents:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC

</session-factory>

</hibernate-configuration>

Move that <mapping> tag to the bottom, near the other one.

That should be it.

Giulio

It works fine now. I have no idea how that damnable extra mapping became inserted.

Thanks very much for the help.

Cut and paste introduces funny errors in repetitive tasks (not to mention Find and Replace) ;)
