hibernate.cfg.xml required in version 2.x?

[Lance Hill]

I had Hibernate 1.2 working okay in a simple junit test. Now I am trying to get it working in an simple Struts application. I have two questions:

1. Is is now required to provide a hibernate.cfg.xml file? Whenever I try to run a new test with the 2.1 version of Hibernate, I get the following error:
net.sf.hibernate.HibernateException: /hibernate.cfg.xml not found

2. Where do I put the hibernate.properties and hibernate.cfg.xml files? I thought that putting them into the WEB-INF/classes folder would work, but I am hoping someone can confirm.

Make sure you have hibernate.cfg.xml in the classpath.

You don't need both the files. You can either have a properties file or an xml file for configuration. WEB-INF/classes is fine.

I had the same problem and got it solved.

1) hibernate.cfg.xml into WEB-INF/classes/
2) obtain an URL to this file
URL url = MyClass.class.getResource("/hibernate.cfg.xml");
Make sure MyClass is part of your web-app
3) Configure hibernate
new Configuration().configure(url);

I would like to add that you must be carefull to create only one time the SessionFactory as this is quite a consuming task.

How can I add the hibernate.cfg.xml to the classpath ?

Under Eclipse, it is allowed to add only jar files ?

I'm developping a standalone application and using hibernate Synchronizer.

[Alexandru Popescu]

You just need to add to classpath the directory containing the xml file .

./pope

Thank You!
It works.

I still have a problem. The mapping files are not found.

How do you make sure you are only loading sessionFactory once in a web app? With a singleton, or at server startup time? When do you clean it up? Thanks,

This is presented very detailed on the Hibernate official reference first chapter: Quickstart with Tomcat.

We had the 'hibernate.cfg.xml not found' problem when developing
IBM WebSphere Portalserver portlets with struts and hibernate.

The solution was to have the hibernate.cfg.xml in WebSphere
Application Developer in ./JavaSources and get the hibernate
configuration at runtime this way:

File f=new File(servlet.getServletContext()
.getRealPath("/WEB-INF/classes/hibernate.cfg.xml"));

Configuration c = new Configuration().configure(f);

This is portable from WSAD to WPS
