Question

I am new to Hibernate, reading this book “Java persistence with Hibernate” and I am trying to implement the example from there. So far my Ant build is successful, but when I try to execute the class containing the main method I am getting this error message:

19-Nov-2011 18:40:09 org.hibernate.cfg.Environment <clinit>

It is clear that hibernate can’t find my config file, which is located in the root dir.

Project

+lib
<all required libraries>
+src
  +hello
    HelloWorld.java
    Message.java
    message.hbm.xml
  +persistence
    HibernateUtil.java
build.xml
hibernate.cfg.xml

My the complete source code can be found here: http://pastebin.com/bGDUrxUf

I have a running MySQL server with a database hibernateapp and table messages

Thanks 🙂

Your hibernate.cfg.xml needs to be inside the src directory; otherwise it’s not covered by Ant’s copymetafiles target, so it won’t end up in your compiled classpath.
