I can't find anywhere on the website the version of the JDK needed for hibernate. I am currently using hibernate2.jar, and am getting the following error:

Initializing Hibernate
log4j:WARN No appenders could be found for logger (net.sf.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.
java.lang.NoClassDefFoundError: javax/xml/transform/ErrorListener

at road2hibernate.EventManager.<init>(EventManager.java:26)
at road2hibernate.EventManager.main(EventManager.java:34)
Exception in thread "main"

I am using Java 1.3. Is Java 1.4 required for Hibernate?

Please read the readme in the libs directory. You need an XML Parser in your classpath if you use 1.3

Thanks.

I added xml-apis.jar to my classpath and it worked.
