Hello,

I was using Hibernate 2.1.8 in a managed app on a OC4J 9.0.4.0.0 standalone Oracle app server and everything worked fine.
Now, We are migrating to OC4J 10.1.2.0.0 (standalone Oracle 10G app server) and I receive the following exception:
Code:
net.sf.hibernate.HibernateException: Could not locate TransactionManager
   at net.sf.hibernate.transaction.JNDITransactionManagerLookup.getTransactionManager(JNDITransactionManagerLookup.java:26)

   ... 24 more


I think this is due to the net.sf.hibernate.transaction.OrionTransactionManagerLookup which I've specified as the 'hibernate.transaction.manager_lookup_class' because it specifies that the TransactionManager is located at JNDI namespace 'java:comp/UserTransaction' but I think this isn't the TransactionManager but just the UserTransaction (did Oracle change this?). Can this be possible?

Does anyone know how to fix this? I might write my own TransactionManagerLookupClass but I don't know where Oracle publishes the TransactionManager in 10G.

Is it possible they are just changing this to complicate the configuration and migration for us (Hibernate folks) because they have TopLink?

Thanx mates,

Stijn

Hi,

Did you get a solution for this problem? Same thing happens to me when SessionFactory is to be built.

I was looking for a way to get a TransactionManager from OC4J, to write a TransacionManagerLookup class, but it seems that OC4J doesn't publish TransactionManager anywhere.

So I tryied to get it from OC4J instance class, as I could see, there is a class com.evermind.server.ApplicationServer with an attribute called instance this is an instance of itself. The problem is, when I try to access this attribute, an exception (java.lang.IllegalAccessException) is thrown and this class has a method that returns an TransactionManager.

Do you know something else?

Thanks

The TransactionManager is published at "java:comp/pm/TransactionManager" I had to decompile some code to find this out but normally it should work...

Greetz,

If one of you could verify this and submit a transactionmanager lookup class to JIRA, we can include it with the upcoming release of 3.1. An interesting question would be if this URI is valid for all versions of OAS or only 10g?

From what I can see in the containers classes (903 - 904 - 10G), this should work for all OC4Js.
MediaSonic, can you give some input when you tried this, please.
How can i post my transactionmanager lookup class to JIRA?

Hi Stijn,

First of all, thank you for the answer and solution, I have changed class "org.hibernate.transaction.OrionTransactionManagerLookup", rebuilt and now it's working well, please send your version to the official repository.

Cheers,
Emilio Numazaki

Oh yes, about the test, UserTransaction is available in older version, but I guess TransactionManager lookup is done in the same way. Unfortunately I haven't old version here.

Cheers,
Emilio

Hi,

Could somebody validate the above statement.? If the above statement is correct, you don't have to mention the TransactionManager Lookup class as one of the hibernate properties when using with Spring framework.

In spring, you can do the following:

<bean id="jtaTransactionManager" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName"><value>java:comp/pm/TransactionManager</value></property>
</bean>

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource"><ref local="dataSource"/></property>
<property name="jtaTransactionManager"><ref local="jtaTransactionManager"/></property>
<property name="mappingResources">
<list> <value>petclinic.hbm.xml</value>
</property>
<property name="hibernateProperties">
<props>
<prop key ="hibernate.dialect">org.hibernate.dialect.Oracle9Dialect</prop>
</props>
</property>
</bean>

Yes, it is... I've changed the class and now it is working very well.
