Hi guys
I am using
Hibernate 3.0
MS SQL Server 2000
RAD Version: 7.0.0
The WebSphere 6.1 is not standalone, it comes with RAD 7 !!!
I am trying to configure Hibernate in non-managed environment which is to use JTA in BMP environment.
I do realize that using the
JTATransactionFactory would prvide for me as the Book [Java Persistence with Hibernate ] says (page 99) :
The JTATransactionFactory enables correct session scoping and propagation for JTA if you decide to use
SessionFactory.getCurrentSession() method
This is the hibernate.cfg.xml
Code:
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!-- Database connection settings -->
<property name="hibernate.connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
<property name="connection.url">jdbc:sqlserver://localhost:1433;DatabaseName=db1</property>
<property name="connection.username">user1</property>
<property name="connection.password">password</property>
<!-- bean-managed transaction -->
<property name="hibernate.transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</property
<property name="hibernate.transaction.maneger_lookup_class">org.hibernate.transaction.WebSphereExtendedJTATransactionLookup</property>
<property name="jta.UserTransaction">java:comp/UserTransaction</property>
</session-factory>
</hibernate-configuration>
Here is the code inside Stateless Session Bean
I am trying to run
Code:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.websphere.naming.WsnInitialContextFactory");
env.put(Context.PROVIDER_URL, "iiop://localhost:2809/");
Context ic = new InitialContext(env);
configuration = new Configuration().configure(someURL);
sessionFactory = configuration.buildSessionFactory();
// the following line causes error
Session session = (Session) sessionFactory.getCurrentSession();
The error occurs when I am attempting to get current session which is supposed to be associated with UserTransaction.
here is the error I get
Code:
DEBUG [P=392992:O=0:CT] (SessionImpl.java:220) - opened session at timestamp: 11852124398
DEBUG [P=392992:O=0:CT] (JTATransaction.java:57) - Looking for UserTransaction under: java:comp/UserTransaction

I am wondering:
1. If this error occurs because I am trying to run this code in WAS 6.1 that comes with RAD ?
2. Do I need to run this code in Session Bean ONLY ?
Thanks for your help!
