Is that line
the line 52 of LoginAction.java as mentionned here:
Could it be that you ClassCastException is not hibernate problem, but rather you having you struts-config wrong?

Thanks for your time but the line 52 is
_RootDAO.initialize();

Hi seybaa !!
I have the same problem in my project. Did you find the solution to it????

Thanks!

<property name="hibernate.transaction.factory_class">
net.sf.hibernate.transaction.JBossTransactionManagerLookup
</property>
is wrong.

It can be like this:

<property name="transaction.factory_class">
net.sf.hibernate.transaction.JTATransactionFactory
</property>
<property name="hibernate.transaction.manager_lookup_class">
net.sf.hibernate.transaction.JBossTransactionManagerLookup
</property>

You are assigning look up class the transaction factory class, that is why the classCastException.
