Hi,

this´s my first time using hibernate.
I use Hibernate 3.0, Tomcat and J2ee Servlets.

I get this error when I call
sessionFactory = new Configuration().configure().buildSessionFactory();


....
Initial SessionFactory creation failed.java.lang.NoClassDefFoundError: org/hibernate/cfg/Configuration
log4j:WARN No appenders could be found for logger (org.apache.catalina.session.ManagerBase).
log4j:WARN Please initialize the log4j system properly.
...

I have this libraries in my WE-INF/lib directory
commons-logging.jar
commons-collections.jar
cglib.jar
dom4j.jar
ehcache.jar
log4j.jar
hibernate3.jar
jta.jar
cglib.jar
c3po.jar
asm.jar
asm-attsr.jar

I´m using pool conections with Mysql
I send you my configuration:
//--------------------------------------------

Please, could you help me??

Your runtime CLASSPATH does not include the hibernate3.jar file. That is why the class loader can't find it.
