I've created a webapp as a war and placed the config file in the webapp's classes directory which is in the webapp. When the code builds a session factory, it throws an exception that it can't parse the configuration file. I've tried a few different config files, but the result is the same. I've also changed the package path in the code to a config file that doesn't exist, and hibernate throws an exception saying it can't find the file - so I assume it's finding it ok.

The webapp is deployed on Tomcat 5, and the JDK version it's compiled with is 1.5.0_06.

Do I have to do anything other than have the config file on the classpath?

TIA

There are multiple reasons why the configuration file cannot be parsed, to check them I would suggest the following steps:
- Change the debug level of you're log4j.configuration, set org.hibernate to DEBUG
- Check if you're configuration is valid XML with an external tool
- Make sure all required jars for hibernate are in you're classpath

If this doens't help post again with more detailed logging.

The debug I'm getting is:

Seems something to be wrong with you're DTD. Make sure the DTD is contained in you're classpath or the server you're running can access them via http.

I've seen this type of error before when I had the hibernate JAR being loaded by the bootstrap class loader. I think there's a bug in DTDEntityResolver that can result in an NPE if the jar is loaded by the bootstrap class loader. Don't know how you could be causing that to happen with a web app though, unless you've got the hibernate jar in the JRE's System Extensions directory or something.
