Hi all,

I am completely new to hibernate and was trying out my first hibernate program.

SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();

This is throwing null pointer exception... I have hibernate.cfg.xml file in the build path( inside /src folder outside any package). I even see the file in the build path after compilation. But when i try to run its throwing exception. So how do i handle this? am i doing something wrong? any suggestion/help is most welcome. Thanks

can you post the stack trace please?

thank for responding but i got it working. but am having one more problem, hibernate.cfg.xml is being called but its not able to find the mapping file specified xxx.hbm.xml I have placed this xxx.hbm.xml in src folder next to all .java files. am I doing anything wrong?

Following is what i get ...

org.hibernate.MappingException: Resource: contact.hbm.xml not found
at org.hibernate.cfg.Configuration.addResource(Configuration.java:442)
at org.hibernate.cfg.Configuration.parseMappingElement(Configuration.java:1381)
at org.hibernate.cfg.Configuration.parseSessionFactory(Configuration.java:1353)
at org.hibernate.cfg.Configuration.doConfigure(Configuration.java:1335)

at mypackage.InsertServlet.main(InsertServlet.java:15)
Exception in thread "main" java.lang.NullPointerException
at mypackage.InsertServlet.main(InsertServlet.java:37)

Thanks foe nay suggestions/idea...

Try specifying the full path of the mapping file in the configuration file.
e.g.:

I even tried specifying full path name in the tag.. But it still didnot work
C:/HibernateExample/src/java/mypackage/contact.hbm.xml

Can you please let me know how did you solve this problem.. i face the similar problem..
