Likely yours. I just set up a fresh Hibernate install on Tomcat 5.5 (with Log4j)
with no problems. Define what you mean by "didn't work".

As I said, for Hibernate under Tomcat (4.1.18 and 4.1.31), no matter where
I put the hibernate.cfg.xml, including WEB-INF/classes, I got the message
that the file is not to be found when we reach the following code:

sessionFactory = new Configuration().configure()
.buildSessionFactory();

2005-02-18 15:28:00,968 WARN http-8080-Processor4
net.sf.hibernate.cfg.Configuration - /hibernate.cfg.xml not found

I've considered trying Tomcat 5.0.x but it seems that first I need to
figure out which ones and adapt a couple of settings in server.xml and/or
web.xml to get it to stop crashing.

What version of Hibernate are you using? When I remove the config file, I get
this in the log: (line breaks inserted to prevent wrap and logging set to INFO
level)

Does that look like what you're getting? I assume you're using some build tool.
Are you sure that the config file is being built to the right place?

I was using 2.1.6 and I upgraded to 2.1.8. The above is almost exactly
what I still get. I am positive that I have a file hibernate.cfg.xml in my
application's WEB-INF/classes folder.
It's the same config file that was at the root of the Eclipse project that
didn't require an absolute path to find it.

Believe me, I've really had to keep trying before getting to this point:

Tomcat can now see hibernate.cfg.xml and log4j.properties which are in my
WEB-INF/classes folder as per the documentation.
What isn't in the documentation is whether the absolute path for the web
application needs to be
<CATALINA_HOME>/webapps/<app_folder>/WEB_INF/classes

because from what I observe, only then things work as they are supposed to.
If I am to use another installation path for the application, I'm stuck
with e.g using initialization servlet or probably a ResourceBundle to pass
the path to Hibernate's Configuration class ?

No, it does not.

What do you mean by "another installation path"? What path, and how do you set
it up for Tomcat to access it?

C:\\myWebApp

<Context path="/something" docBase="C:\\myWebApp" />

In such a case, Tomcat cannot find
C:\myWebApp\WEB-INF\classes\hibernate.cfg.xml

Same goes for
C:\myWebApp\WEB-INF\classes\log4j.properties

Though from the way I understand the documentation they're supposed to be
found.
It's when I use the following installation folder that e.g
Hibernate's no-args configure() succeeds as Tomcat can find the
hibernate.cfg.xml in:

<CATALINA_HOME>/webapps/<app_folder>/WEB_INF/classes

Try docBase="C:\myWebApp".

humm... any particular reason why we'd expect that to make a difference?
