Hi,

I am developing a workflow management system using jboss-jbpm. I am using mysql as database,
and using hibernate for OR mapping.

Problem: I got a parent table(Name:User_Table) and a child table(Name:Member_Table)
There is a primary key foreign key association with User_Table and Member_Table.
The primary key field in User_Table is an autoincriment field.
Two Value Objects(VO) are there for each Tables.
when i save the datas into the User_Table one row is also inserted in the
Member_Table,but the foreign key column is null.

My *.hbm.xml files are given below


1)Membership.hbm.xml
<class name="MembershipVO" table="Member_Table">
<id name="id" type="int" column="ID_" />
<property name="name" type="string" column="NAME_" />
<property name="role" type="string" column="ROLE_" />
<property name="group" type="int" column="GROUP_" />
<property name="memberClass" type="string" column="CLASS_" />
<many-to-one name="userVO" class="UserVO" column="USER_"></many-to-one>
</class>

2)User.hbm.xml

<class name="UserVO" table="User_Table">
<id name="id" type="int" column="ID_" >
<generator class="native"></generator>
</id>
<property name="userName" type="string" column="NAME_" />
<property name="password" type="string" column="PASSWORD_" />
<property name="email" type="string" column="EMAIL_" />
<property name="userClass" type="string" column="CLASS_" />
</class>



Thanks in advance

Can you post some sample code which creates and persists the objects? Nothing jumps out in the mapping as a possible cause (though I would suggest putting a <generator/> node in the id field for the Membership class.

Dear Matbrown .

Thanks for the reply.
I added the generator class and now my code is working fine.
