As the error says in the stack trace you are missing a "name" attribute in your "list" element.



The DTD says it is required.


See the DTD for all mapping document rules...
http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd

i changed taht now
still i getting same error

Now that bookdata list looks like this in orderdata.hbm.xml

<list name="BookData"
role="BookData"
table="BookData"
lazy="true"
cascade="none"
>
<key
column="orderId"
>
</key>

<one-to-many
class="BookData"
/>

</list>
previosli i haven't posted bookdata.hbm.xml

Bookdata.hbm.xml

</hibernate-mapping>

I think if you read the stack trace carefully you will see the error, just as I did before.

Also, as mentioned above, see the DTD. It is unambiguous in what is legal syntax for a mapping document.

These are simple syntax errors. Take the time to look closely. Debugging via forum posts is slow for everyone.

If you can't spot the error, comment out everything in the mapping document and start again, umcommenting sections until you get the error again.

Good luck

thank u for ur guidence

I have checked everything

Still i not able find the error in xml file
