Name and version of the database you are using:
oracle 9i

There is this error:
06:09:43,984 INFO [TransactionFactoryFactory] Transaction strategy: net.sf.hibernate.transaction.JTATransaction
06:09:44,000 ERROR [TransactionFactoryFactory] Failed to instantiate TransactionFactory
java.lang.InstantiationException: net.sf.hibernate.transaction.JTATransaction

Quite confused what happens, and how to heal it?

Thanks!

You need to specify the "transaction manager look up class" property in your cfg.xml file. For example, if you are using Weblogic, it would be:

hamids,

Thank you so much for your message!

now I add the TranactionManagers, and the hibernate.cfg.xml looks as following:

<?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">

<property name="transaction.manager_lookup_class">net.sf.hibernate.transaction.WeblogicTransactionManagerLookup</property>

I'm looking forawrd to hearing from you!

Search the forum, there are *many* posts on this issue. If you are using an app server, in your case Weblogic, here are the basic steps:

1. Specify a datasource in Weblogic, via the admin console.
2. Tell hibernate where the datasource is (via your hibernate.cfg.xml) file.
3. Specify the transaction manager lookup class.

Because I'm a nice guy, here is what your cfg xml should look like:

hi hamids,

thanks for the message. Just wondering whether there is any way that I don't need app server when using hibernate objects.

Also, is it posssible to use a standalone application to invoke hibernate objects?

Paul

I really suggest you start here:

steve,

You'll be really appreciated if you can answer me with a clear decision like "yes" or "no" to the quest "is it posssible to use a standalone application to invoke hibernate objects". because I jsut couldn't find a good way to test hibernate objects.

Regards,
Paul

yes

http://www.hibernate.org/5.html

That's really nice...

after reading those badly organized documemnts, i'm still quite confuse how a standalone java application can invoke a serverside hibernate objects....

do they have JNDI names?
