I have Eclipse Europa and am trying to do a hibernate example in it. 
I am trying to simply add an entry to the database. 
My hibernate.cfg.xml file is as follows: 
Code:
<?xml version="1.0" encoding="utf-8"?>   
<!DOCTYPE hibernate-configuration PUBLIC  
   "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
   "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd" >
 
 <hibernate-configuration>   
  <session-factory>   
   <property name="hibernate.connection.driver_class">org.derby.Driver</property>   
   <property name="hibernate.connection.url">jdbc:derby://localhost:1527/myDB</property>   
   <property name="hibernate.connection.username">me</property>   
   <property name="hibernate.connection.password">mine</property>   
   <property name="hibernate.connection.pool_size">10</property>   
   <property name="show_sql">true</property>   
   <property name="dialect">org.hibernate.dialect.DerbyDialect</property>   
   <property name="hibernate.hbm2ddl.auto">update</property>   
   <mapping resource="Job.hbm.xml"/>   
  </session-factory>   
    
 </hibernate-configuration> 
Eclipse keeps showing errors for this xml. 
An when I run the class with the hibernate code it shows/throws the following error. 
Code:

How do I get this resolved.
My java classes have no package hierarchy.
Is this problem due to Eclipse or is there an error in the xml.
