Transaction Mananger about Sessioin Bean and Hiberante

It take me a long time to investigate Transaction Manager about hibernate and ejb.It's really simple if you find the right materials,just specify some parameters in hibernate.cfg.xml,here is the result:

<1>specify a Datesource :

	<property name="hibernate.connection.datasource">
		java:MSSQLDS
	</property>

It's very important to do this.

<2>specify some other paramethers

	<property name="hibernate.TransactionManagerLookup">
		org.hibernate.transaction.JBossTransactionManagerLookup
	</property>
	<property name="hibernate.transaction.manager_lookup_class">
		org.hibernate.transaction.JBossTransactionManagerLookup
	</property>
	<property name="hibernate.TransactionManagerLookupStrategy">
		org.hibernate.transaction.JBossTransactionManagerLookup
	</property>
	<property name="hibernate.TransactionStrategy">
		org.hibernate.transaction.CMTTransactionFactory
	</property>
	<property name="hibernate.transaction.factory_class">
		org.hibernate.transaction.CMTTransactionFactory
	</property>
	<property name="hibernate.connection.release_mode">
		after_statement
	</property>
	<property name="hibernate.transaction.auto_close_session">
		true
	</property>
	<property name="hibernate.transaction.flush_before_completion">
