Hi!
I get "org.hibernate.HibernateException: Unable to locate current JTA transaction" when trying to get the curretn hibernate session.
See the logs:

[STDOUT] ctx.lookup("java:/hibernate/TesisSessionFactory"): org.hibernate.impl.SessionFactoryImpl@153d2ae
[STDOUT] ctx.lookup("UserTransaction")org.jboss.tm.usertx.client.ServerVMClientUserTransaction@1744dbf


And when executing:

session = HibernateContext.getSession("java:/hibernate/TesisSessionFactory");

or

session = factory.getCurrentSession();

I get:

20:14:04,473 ERROR [Home$Enhance_11] Hibernate genero un error
org.hibernate.HibernateException: Unable to locate current JTA transaction
at org.hibernate.context.JTASessionContext.currentSession(JTASessionContext.java:61)
at org.hibernate.impl.SessionFactoryImpl.getCurrentSession(SessionFactoryImpl.java:507)
at org.jboss.hibernate.session.HibernateContext.getSession(HibernateContext.java:94)

But if I execute:

session = factory.getCurrentSession();

I get a session and then I can lookup, update, insert and delete data.

Using the jmx-console, and listing the JNDI tree I get this items (related to transactions):

java: Namespace
+- TransactionPropagationContextExporter (class: org.jboss.tm.TransactionPropagationContextFactory)
+- TransactionPropagationContextImporter (class: org.jboss.tm.TransactionPropagationContextImporter)
+- TransactionManager (class: org.jboss.tm.TxManager)

Global JNDI Namespace
+- UserTransactionSessionFactory (proxy: $Proxy37 implements interface org.jboss.tm.usertx.interfaces.UserTransactionSessionFactory)
+- UserTransaction (class: org.jboss.tm.usertx.client.ClientUserTransaction)

While the app is loading I get this logs:

I'm deploying hibernate with a .har file. The hibernate-service.xml has:



java:PostgresDSTesis
org.hibernate.dialect.PostgreSQLDialect
java:/hibernate/TesisSessionFactory
org.hibernate.cache.HashtableCacheProvider
yes



and the datasource definition file has:

<?xml version="1.0" encoding="UTF-8"?>
<datasources>
<local-tx-datasource>
 <jndi-name>PostgresDSTesis</jndi-name>
 <connection-url>jdbc:postgresql://127.0.0.1:5432/tesis8</connection-url>
 <driver-class>org.postgresql.Driver</driver-class>
 <user-name>xxxx</user-name>
 <password>xxxx</password>
 <transaction-isolation>TRANSACTION_READ_COMMITTED</transaction-isolation>
 <metadata>
 <type-mapping>PostgreSQL 7.2</type-mapping>
 </metadata>
</local-tx-datasource>
</datasources>

In the WEB-INF/lib I've NO jar related to transactions nor hibernate.
I've this problem with both jboss-4.0.3SP1 and jboss-4.0.4RC1.

What I want is to share the same transaction within the same httprequest,
and make work with JBoss something like Spring's "OpenSessionInView".

What am I doing wrong?

Thanks in advance!
