Hi All,

I have just started learning Hibernate. And following tutorial @ http://www.vaannila.com/hibernate/hiber ... ols-1.html. And have included following jars as user libraries in project:-
antlr-2.7.6.jar,commons-collections-3.1.jar,dom4j-1.6.1.jar,hibernate3.jar,javassist-3.12.0.GA.jar,jta-1.1.jar,log4j-1.2.8.jar,mysql-connector-java-5.1.13-bin.jar,slf4j-api-1.6.1.jar,slf4j-simple-1.6.1.jar.

But when I am running the Main program I am getting following error in console:-

Code:

Notice this line in your output: "7015 [main] INFO org.hibernate.cfg.Configuration - Configured SessionFactory: null". Also look at the stack trace where it shows code in your program (vs. Hibernate code):
at com.vaannila.util.HibernateUtil.<clinit>(HibernateUtil.java:10)
at com.vaannila.course.Main.saveCourse(Main.java:26)
at com.vaannila.course.Main.main(Main.java:15)

HibernateUtil, line 10 is:
sessionFactory = new Configuration().configure().buildSessionFactory();

It looks like HIbernate can't find your configuration file (hibernate.cfg.xml?) which "is by default expected to be in the root of your CLASSPATH." (see Hibernate Core Reference).

Check your classpath and the location of your configuration file and make sure it matches what the tutorial told you to do.

Good Luck!

OK, I just noticed that you double-posted this at Java Ranch and got an answer there. Please don't double post. I wasted a least a half hour trying to figure this out for you. 8-(

This seems to be caused by Hibernate 3.6. It is now dependent on JPA, so it must have a JPA jar in the class path as well. You can find one in the Hibernate 3.6 distro: hibernate-distribution-3.6.0.Final/lib/jpa/hibernate-jpa-2.0-api-1.0.0.Final.jar

@ajhampson: That's great info for me, thanks for still posting about the JPA! If it's of any help to others just getting started with the tutorial, I also needed the H2 jar from here to get the 'NativeApiIllustrationTest' JUnit test to run successfully.
