Hi.
I created a project as described in this tutorial.
When I run it, I get “/hibernate.cfg.xml not found”.
What is missing?
I understand it should be in the classpath.
What I don’t understand is how to accomplish this.
It is under “src” directory is compiled into the classes directory. I thought that should do it for the classpath thing. What is missing?
Thank you.
Kirill.
