hi, I'm new to hibernate, now I'm using BEA Weblogic8.1 + Borland JBuilder2005. I tried to use hibernate api in stateless session beans, but when it goes to:

Configuration cfg = new Configuration();

and got the following exception, while I've added commons-logging.jar in the project library:

java.rmi.RemoteException: EJB Exception: ; nested exception is:

Hibernate uses Jakarta Commons Logging (I assume from that stack trace). You must ensure that you include all of the necessary JARs for Hibernate (packaged with it) in your classpath/EAR/WAR.
