Exception using JTATransaction in WebSphere 6 --------------------------------------------- Key: HHH-1064 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1064 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.0.5 Environment: Hibernate 3.0.5, 3.1b3, IBM WebSphere 6 AS, Spring 1.2.5 Reporter: Andrey Grebnev Assignee: Gavin King Fix For: 3.1 rc3 I have already posted this bug to you http://opensource2.atlassian.com/projects/hibernate/browse/HHH-1053 but you rejected it. Now I concrete it according discussion in forum http://forum.hibernate.org/viewtopic.php?t=948460 I am porting my application AtLeap (https://atleap.dev.java.net) from Hibernate 2.1.8 and Spring 1.1.5 to Hibernate 3.0.5 and Spring 1.2.5. AtLeap was working correctly under IBM WebSphere 6 AS with following settings: <property name="hibernate.transaction.factory_class" value="org.hibernate.transaction.JTATransactionFactory"/> <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.WebSphereTransactionManagerLookup"/> However when I have ported AtLeap into Hibernate 3.0.5 and Spring 1.2.5 I have the following error: [05.10.05 22:12:06:531 GEST] 00000058 Helpers W NMSV0605W: A Reference object looked up from the context "agrebnevNode01Cell/nodes/agrebnevNode01/servers/server1" with the name "jta/usertransaction" was sent to the JNDI Naming Manager and an exception resulted.

Please look at the following code from JTATransactionFactory utName = props.getProperty(Environment.USER_TRANSACTION); if (utName==null) { TransactionManagerLookup lookup = TransactionManagerLookupFactory.getTransactionManagerLookup(props); if (lookup!=null) utName = lookup.getUserTransactionName(); } if (utName==null) utName = DEFAULT_USER_TRANSACTION_NAME; We can see that we call getUserTransactionName Now let's look at WebSphereTransactionManagerLookup public String getUserTransactionName() { return version==5 ? "java:comp/UserTransaction": "jta/usertransaction"; } the version variable will be initialized only after calling getTransactionManager, but we do not do it. As result we have utName equals jta/usertransaction, but it should be java:comp/UserTransaction -- Andrey Grebnev http://www.jroller.com/page/agrebnev
