I'm trying to switch from Hibernate 2.0.3 to 2.1.3 but I keep getting into trouble. I've resolved them so far (had to switch a lot of libraries, try to include jar files from the lib directory).

Now when I start my program I get the following exception

java.lang.NoClassDefFoundError: javax/transaction/Synchronization

This is a j2ee class and not a j2se 1.5 class.

Is Hibernate 2.1.3 only to be used in j2ee environments? If it is, are there then non-Hibernate alternatives that can still be used in j2se? I don't want to switch to j2ee, too big for my needs.

You are missing jta.jar in your classpath. Take a look at the readme in the lib directory for a list of required jars.
