You are missing the mapping of the Company class.
Every class you intend to persist must be defined in one or more mapping files.

Well, the mapping file of the Company is:

Code:

<hibernate-mapping>
    <class name="Company" table="company">
      <id name="cnpj" column="cnpj">
         <generator class="assigned"/>
      </id>
      <property name="name" column="name"/>
      <property name="address" column="address"/>
      <property name="number" column="number"/>
      <property name="complement" column="complement"/>
      <property name="burgh" column="burgh"/>      
         <one-to-one name="monthlyFee" class="MonthlyFee" 
            constrained="false" outer-join="false"/>         
    </class>
</hibernate-mapping>

Each Table or java bean contains its mapping file.

Code:

<id name="company" column="cnpj">
and
private Company company; 

So Hibernate use the Company object and serialize it to get the id.
What you want is probably add an extra id property.
