how to implement lazy loading in hibernate

I have 3 tables with mapping CompanyRegistration

    <one-to-one name="referenceDb"   class="com.hibermappings.ReferenceDb"  cascade="all" constrained="false" /> 
    <one-to-one name="registration"  class="com.hibermappings.Registration" cascade="all" constrained="false" /> 

    <property name="companyName" type="java.lang.String">
        <column name="companyName" length="50" />
    </property>
    <property name="companyProfile" type="java.lang.String">
        <column name="companyProfile" length="50" />
    </property>
    <!--<property name="functionalArea" type="java.lang.String">
        <column name="functionalArea" length="50" />
    </property>
    --><property name="contactPerson" type="java.lang.String">
        <column name="contactPerson" length="50" />
    </property>
    <property name="website" type="java.lang.String">
        <column name="website" length="50" />
    </property>
    <property name="country" type="java.lang.String">
        <column name="country" length="50" />
    </property>
    <property name="state" type="java.lang.String">
        <column name="state" length="50" />
    </property>
    <property name="city" type="java.lang.String">
        <column name="city" length="50" />
    </property>
    <property name="address" type="java.lang.String">
        <column name="address" length="50" />
    </property>
    <property name="email" type="java.lang.String">
        <column name="email" length="50" />
    </property>
    <property name="mobile" type="java.lang.String">
        <column name="mobile" length="50" />
    </property>
    <property name="phone" type="java.lang.String">

            </generator>
    </id>
    <one-to-one name="currentprofile" class="com.hibermappings.Currentprofile"  constrained="false" />

    <property name="referencedId" type="string">
        <column name="referenced_id" length="30" />
    </property>
    <property name="password" type="string">
        <column name="password" length="10" />
    </property>
    <property name="associateCode" type="string">

    </property>
    <property name="userType" type="string">
        <column name="user_type" length="50" />
    </property>
    <property name="numericId" type="integer">
        <column name="numeric_id" />
    </property>
</class>

    </property>
    <property name="academytype" type="java.lang.String">
        <column name="academytype" length="75" />
    </property>
</class>

Now when I am trying to load the object from CompanyRegistrtion table with companyId the child objects of Referencedb and Registration is also loaded and finally I got the exception.. How can I iplement the lazy loading.

Hibernate uses lazy loading by default. However, it is explicitly disabled in your mapping:

<one-to-one name="referenceDb" lazy="false" ... />
<one-to-one name="registration" lazy="false" ... />

Removing lazy="false" should solve your problem.
