I've seen some discussions on this subject, but I could not find a clear answer, so please somebody help me. I am doing a major POC on Hibernate, and these are my first stumbling blocks.

I have all Hibernate required jars in the classpath,
as well as Hibernate mapping files.

Here is my mapping file:


<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 2.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-2.0.dtd">

hibernate-configuration>

<session-factory>
<property name="hibernate.connection.driver_class">COM.ibm.db2.jdbc.net.DB2Driver</property>
<property name="hibernate.connection.url">jdbc:db2://PIERCETI:6789/SKILSTRK</property>
<property name="hibernate.connection.username">db2admin</property>
<property name="hibernate.connection.password">admin</property>
<property name="dialect">cirrus.hibernate.sql.DB2Dialect</property>


<mapping resource="org/ebegoli/hibernate/Level.hbm.xml"/>

</session-factory>

</hibernate-configuration>


I tried without putting DTDs in the classpath (expecting parser to pick it up from the web), and I tried extracting the dtds under the sf/hibernate/.... In any case I get this exception when I run it in my Java Project. I am running it with Eclipse 3.0:
