java.lang.ExceptionInInitializerError occurs when the following line executes:

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

I have the hibernate.cfg.xml file in the correct location. And I am certain the fields are mapped correctly.

Here is the mapping (only 1 field for now!!)

Code:

+--------+---------+------+-----+---------+----------------+
| Field  | Type    | Null | Key | Default | Extra          |
+--------+---------+------+-----+---------+----------------+
| newsid | int(11) |      | PRI | NULL    | auto_increment |
+--------+---------+------+-----+---------+----------------+

NewsVO.hbm.xml
------------------------------------------------------------

Code:

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping
    PUBLIC "-//Hibernate/Hibernate Mapping DTD//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">

<hibernate-mapping>
    <class name="clinton.inet.news.NewsVO" table="news">       
        <id name="newsId" type="int">
            <column name="newsid" sql-type="int"/>
            <generator class="hilo"/>
        </id>   
    </class>
</hibernate-mapping>

Can anyone spot anything wrong going on here..

Thanks in advance
James

I think you need to actually have at least one property on your class that is mapped besides the id/key.

Why do you even both posting an exception without the full stack trace?

David: no, you don't need to map a property.

Fixed problem. Missing *ing jar file.

Will add stacks in future. Reason for not doing it was:

* I had hoped someone would recognise the exception without them.
* The stack was about 100 lines and if someone was that interested then they would probably *kindly* request them.

Or maybe not in this case.

Well, in future you will know to "kindly" add enough information to be able to resolve your problem, as is requested in the instructions for using this forum. Otherwise you waste the time of everyone who must read your post and request the information that you could have chosen to give the first time.
