It probably means you are missing jars from the classpath. I ran into this problem recently, and it didn't seem to me that the Hibernate docs addressed it very well. I got sample programs from the Manning Hibernate book running with the following jars:

antlr-2.7.6.jar
commons-collections-3.1.jar
dom4j-1.6.1.jar
hibernate-cglib-repack-2.1_3.jar
hibernate3.jar
javassist-3.4.GA.jar
jta-1.1.jar
slf4j-api-1.5.2.jar
hsqldb.jar
log4j-1.2.15.jar
slf4j-log4j12-1.5.2.jar

I believe you can swap log4j with commons-logging if you prefer.

When you extract hibernate distro (2.x) you'll have README inside lib directory which lists all the required,optional etc.. And in 3.x they have separated them in to required,optional etc.. inside lib directory.

Ah, but the problem is they aren't right. There are several jars that are required, but not mentioned in the required list. If I remember right, there are two or three required jars not mentioned in any of the lists. I found that a bit frustrating.
