Hello,

I have placed my annotated hibernate classes inside a seperate "commons" jar file. Inside this file I have placed the hibernate.cfg.xml file which looks like this:

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.gjt.mm.mysql.Driver</property>
        <property name="hibernate.connection.password">xxx</property>
        <property name="hibernate.connection.url">jdbc:mysql:///DevsidenNy</property>
        <property name="hibernate.connection.username">xxx</property>
        <property name="hibernate.current_session_context_class">thread</property>
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="hibernate.show_sql">true</property>


      <mapping class="info.devsiden.dsj.persistancetier.data.BildeData" />
      <mapping class="info.devsiden.dsj.persistancetier.data.BildeAlbumData" />
      
   </session-factory>
</hibernate-configuration>

Now, when I deploy the application this file is read, which outputs the following:

Code:

Note that there is no reading of these annotated classes (which are correct BTW, with @Entity, and such).

Now, when I try to use any of the annotated classes, I get the following exception:

Here is one of the annotated classes for reference:

package info.devsiden.dsj.persistancetier.data;

Code:

import org.hibernate.annotations.Proxy;

import javax.persistence.*;
import java.util.Date;
import java.util.Set;
import java.util.List;
import java.util.Collection;
