My hibernate setup throws some exceptions but still works. The exceptions are thrown for every entity class defined in mapping xml. My project sets up on OSGI using equinox. The class which could not be found is definitely in classpath.

Hibernate Configuration

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">

          <property name="show_sql">false</property>
            <!-- C3P0 Connection Pool -->
            <property name="hibernate.connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider</property>
           <property name="hibernate.c3p0.min_size">5</property>
          <property name="hibernate.c3p0.max_size">20</property>
          <property name="hibernate.c3p0.timeout">300</property>
