getting unknown error in my hibernate mapping file

I have three persistent classes named:shops.class,user.class,vehicle.class and three hibernate mapping file shops.hbm.xml,users.hbm.xml,vehicle.hbm.xml
But i am getting following error in my users and vehicle mappingg file:
The content of element type "class" must match

I know this question is asked many times but all of that were related to not using tag. But i had used this tag in all files but still getting this error in users and vehicle file.
Please Help i am badly stuck with this.
Thanks in advance

version must be defined before property and map
Move it to be right after id definition in the users and vehicle hbm

exception here in hbm.xml

<id name="id" />

org.hibernate.exception.MappingException or ConstraintViolation

I am using hibernate 4.1.9. I have Users, and the Users have a list of Accounts, and Accounts have list of Transactions. Here is my hbm.xml
<?xml version="1.0"?>
<class name="User" table="users">
<id name="userId" column="userid">
<generator class="increment"/>
</id>
<property name="username" column="username" not-null="true"/>

</class>

</class>
<class name="AccountType" table="account_types">
<id name="accountType" column="account_type"/>
<property name="accountName" column="name"/>
</class>
If I leave inverse="true" on the list of accounts (in the User) I get the ConstraintViolationException because the userid is not getting put in the insert query. If I take inverse="true" off of the list of accounts, I get org.hibernate.MappingException: Repeated column in mapping for entity: com.joe.data.Account column: accountid (should be mapped with insert="false" update="false")
To clarify lowercase names are database columns names, camel case are class variable names. I know Transaction class isn't working quite right yet, but if I could get the Accounts to insert I could do the same thing to get the Transactions to insert.
Edit: I added the many-to-one on the Account class and now I am getting another exception where hibernate is complaining about missing a getter for userId in com.joe.data.Account

In order to get inverse="true" work, you need to define many-to-one for User in Account and for Account in Transaction class and mappings.

Kindly show me the mistakes I have made.. I want to use one to many relation AffiliateDO->AddressDO

It looks like your mapping of the parent class is referring to AddressDO, but the subsequent child mapping is referring to Address (No "DO")... If I had to guess, you should change the second mapping to AddressDO (or visa versa). In any event, looks like a typo to me.

Considering Do as a typo error in Addrees xml, The Address mapping seems incorrect, there must address_id must be many-to-one currently it is generated new one.

Migrating Hibernate 3.2.5 to 3.6

Currently We are facing a lot of problem in migrating our Application from Hibernate 3.2.5 to 3.6.1.

Focus on com.sampleproject.client.beansdm.metadata.uicontrols.InputControl joined-subclass mapping there is a field named btnName. Its working fine with 3.2.5 version but when i changed it to newer hibernate version it stops responding.
Is there any possible jar conflicts ?
Please help.
Thanking You,
Regards,

The Hibernate Version Comparison guide states when moving from 3.5 to 3.6 that:
However, for users still using hbm.xml
you should be aware that we chose to
use the
org.hibernate.cfg.EJB3NamingStrategy
used in AnnotationConfigration instead
of the older
org.hibernate.cfg.DefaultNamingStrategy
historically used on Configuration.
This may cause naming mismatches; one
known place where this is an issue is
if you rely on the naming strategy to
default the name of a association
(many-to-many and collections of
elements) table. If you find yourself
in this situation, you can tell
Hibernate to use the the legacy
org.hibernate.cfg.DefaultNamingStrategy
by calling
Configuration#setNamingStrategy and
passing it
org.hibernate.cfg.DefaultNamingStrategy#INSTANCE
The NamingStrategy interface defines several methods like String foreignKeyColumnName(String propertyName, String propertyEntityName, String propertyTableName, String referencedColumnName)used to determine the names of columns and associations which are implemented by the EJB3NamingStrategy. I suggest you look at the implementation of these methods in the EJB3NamingStrategy class and see how it is transforming property names to column names.
It looks like hibernate is now adding the underscores to what it expects the column name to be in the DB via one these transformations, and is upset when it can't find the resultant column name 'btn_name' in your database.
