here is my persistent.xml:
<persistence-unit name="jpa_ora" transaction-type="JTA">
  <provider>org.hibernate.ejb.HibernatePersistence</provider>
  <jta-data-source>java:OraDS</jta-data-source>
  <mapping-file>META-INF/orm.xml</mapping-file>
  <class>ca.teranet.rts.model.User</class>
  <class>ca.teranet.rts.dao.UserSession</class>
  <exclude-unlisted-classes>true</exclude-unlisted-classes>
  <properties>
   <property name="hibernate.show_sql" value="true" />
   <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" />
   <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup" />
      </properties>
 </persistence-unit>

and i am using TransactionManagement.Container in my Stateless EJB. I have put the hibernate-jpa-2.0-final.jar in server/default/lib folder.

The problem is :
Whenever i invoke a method to persist an object, sometimes it works well and save it into DB and sometimes it wont, just increases the hibernate_sequence value and and comes out silently without even throwing an exception but does not fire an insert query .

But when i run the same application over JBoss6.0 it works perfectly.

Any clue on this ........
