Hi all
i am using static inner class and try to make the databse by setting property <property name="hbm2ddl.auto">create</property>
while on searching in net and other tutorial i am able to create the database
i used the following hbm.xml file for inner class

here Dataparameter is outer class and MemoryExpression is the inner class


<subclass name="com.daffodilwoods.framework.core.view.client.dataparameter.DataParameter" discriminator-value="DataParameter" >
<property
name="editable"
column="editable"/>
<property
name="defaultRowOn"
column="defaultRowOn"/>
<property
name="memoryAddress"
column="memoryAddress"/>
<property
name="searchKey"
column="searchKey"/>
<property
name="explicitFilter"
column="explicitFilter"/>
<!-- <many-to-one name="MemoryExpression" column="memoryDataObjectId" cascade="all"> </many-to-one>
<many-to-one name="memoryExpression"
column="memoryExpression" cascade="all"/>

<class name="com.daffodilwoods.framework.core.view.client.dataparameter$MemoryExpression"
table="MemoryExpression">
<id name="Id"
column="Id">
<generator class="increment"/>
</id> -->

<component name="id" class="com.daffodilwoods.framework.core.view.client.dataparameter.DataParameter$MemoryExpression" >


<property
name="memoryDataObjectId"
column="memoryDataObjectId"/>

<property
name="memryViewId"
column="memryViewId"/>
<property
name="type"
column="type"/>
<property
name="memoryFuntion"
column="memoryFuntion"/>

</component>
</subclass>


But when i try to insert the record from Hibernate Util it show the following error
