Hi,

I have the beans Company and MonthlyFee.
The relationship between these beans is 1-to-1.

How can I do to set to lazy=true in MonthlyFee.???

thanks

Hi, my mapping file are:

Code:

<hibernate-mapping>
    <class name="Company" table="empresa">
      <id name="cnpj" column="cnpj">
         <generator class="assigned"/>
      </id>
      <property name="name" column="nome"/>
      <property name="corporateName" column="razao_social"/>
      <property name="address" column="logradouro"/>
      <property name="number" column="numero"/>
         <one-to-one name="monthlyFee" class="MonthlyFee" 
            constrained="false" outer-join="true"/>         
    </class>
</hibernate-mapping>

<hibernate-mapping>
    <class name="MonthlyFee" table="mensalidade">
        <id name="cnpj" column="cnpj"> 
           <generator class="foreign"> 
              <param name="property">company</param> 
           </generator> 
         </id> 
         <one-to-one name="company" class="Company" 
           constrained="true" outer-join="false"/>      
        <property name="value" column="valor"/>
    </class>
</hibernate-mapping>

but when I use sessionCreateQuery("from Company");

it returns the ArrayList of Company, where within this bean has
the monthlyFee object. So within monthlyFee has company again
an so on.

I don

if it is possible the it is better to drop 1-to-1 and put data in to the same table . You can create Views for logic to "hide" phisical data storage details.
