hibernate persistence -

i work hibernate create hibernate.cgf.xml , mapping file. create class java entity , hibernateutil.java , when run test main generate this:

exception in thread "main" net.sf.hibernate.mappingexception: no persister for: fr.hibernate.projet.model.employe     @ net.sf.hibernate.impl.sessionfactoryimpl.getpersister(sessionfactoryimpl.java:347)     @ net.sf.hibernate.impl.sessionimpl.getclasspersister(sessionimpl.java:2690)     @ net.sf.hibernate.impl.sessionimpl.getpersister(sessionimpl.java:2697)     @ net.sf.hibernate.impl.sessionimpl.savewithgeneratedidentifier(sessionimpl.java:763)     @ net.sf.hibernate.impl.sessionimpl.save(sessionimpl.java:738)     @ fr.hibernate.projet.test.test.main(test.java:32) 

the database still empty.

"no persiter" means there no mapping definition given type. did load mapping definitions in program?

edit: may have issue configuration file. must on path can found. google.
