and her is the errors.

(impl.SessionFactoryObjectFactory 82 ) no JNDI name configured
java.lang.UnsupportedOperationException: The user must supply a JDBC connection

Exception in thread "main"

Okay there are many possible reasons for that,:
1. check your DB-Driver
2. Check your web.xml file if you entered your JNDI settings
3. Check your server-config file if you entered your JNDI
4. Check if your DB is running.

Hope one of them fits.

Bye
