hi
I am new to Hibernate and was following the hibernate reference pdf.

can any body help me on this .

i paste the cfg file and the hbm.xml

i use Oracle 10g as DB and JDBC version is 9

But i am able to locate the logfactory class with the commonslogging jar.


as i followed and built a sample,it throws the following error



Initial SessionFactory creation failed.java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
