Name and version of the database you are using: OracleEX
The generated SQL (show_sql=true):
Debug level Hibernate log excerpt:
G'Day guys,
I was able to get the hibernate 1st tutorial wokrin fine. Was using OracleEX as the DB and everything went smooth. Then i decided to try the servlet. I downloaded and installed apache and eclipse plugin and the i tested it with a basic servlet which just outputs text and it works fine, but as soon as i try to do this in my servlet 'HibernateUtil.getSessionFactory().getCurrentSession().beginTransaction();' it throws the exception 'Initial SessionFactory creation failed.java.lang.NoClassDefFoundError: org/hibernate/cfg/Configuration'. Now the actual line that throws the error is the HibernateUtil class and is the 2nd line here :-
System.out.println("----------- HibernateUtil - 1");
Configuration conf = new Configuration();
System.out.println("----------- HibernateUtil - 2");
conf.addFile("../hibernate.cfg.xml");
System.out.println("----------- HibernateUtil - 3");
// Create the SessionFactory from hibernate.cfg.xml
sessionFactory = conf.configure().buildSessionFactory();
System.out.println("----------- HibernateUtil - 4");
"----------- HibernateUtil - 2" is never outputted to the screen.
I have checked all the references. It even displays the correct package 'org.hibernate.cfg.Configuration' when i hover my mouse over the code in Eclipse. I have removed the 'hibernate3.jar' file and re-added it but nothing seems to work. I cannot understand why this exception is occurring.
PLEASE help me out here guys. Any sort of help will be highly appreciated.
thanks,
pix.
