Hibernate TABLE is not mapped

I receive this error

When attempting to deploy my application.

My class is called ServerSettings.java - it looks like

static public ServerSettings GetServerSettings() throws Exception
{
    List retList = null;
    ServerSettings ss = null;
    try {
        Session hsession = HibernateUtil.currentSession();
        retList = hsession.createQuery("from ServerSettings as ss").list();
        if (retList == null || retList.size() <= 0)
            return null;
        ss = (ServerSettings) retList.get(0);
    } 
    finally
    {
        HibernateUtil.closeSession();
    }
    return ss;

our persistence.xml looks like

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0"
   xmlns="http://java.sun.com/xml/ns/persistence"         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="

     <!-- <sproperty name="hibernate.hbm2ddl.auto" value="create-drop" /> -->
     <!-- <property name="hibernate.show_sql" value="false" /> -->
  </properties>

We also have a hibernate.cfg.xml

   <session-factory>
      <property name="datasourceName">java:jboss/datasources/MySqlDS</property>
      <property name="dialect">org.hibernate.dialect.MySQLDialect</property>

   </session-factory>

</hibernate-configuration>

and a ServerSettings.hbm.xml

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC

        "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

</class>

Usually this error is caused when using table name instead of class name in hql - but that's not the case here. Also this was working previously in JBoss AS5 - I'm moving it to JBoss AS7. Any advice?

<class name="com.mycompanyServerSettings"
                          ^-- A dot is missing here

Moreover, the ServerSettings.hbm.xml isn't referenced in the main hibernate.cfg.xml file. You should have such an element in the session-factory element:

<mapping resource="com/mycompany/ServerSettings.hbm.xml"/>
