Im trying to port a J2EE application to Web AS 6.30 that uses the Hibernate framework (http://www.hibernate.org) and container managed transactions. To make it work I have to write a class that looks up the transaction manager and define it as transaction.manager_lookup_class in my hibernate.cfg.xml.
This would be easy if I know how to lookup or instantiate the javax.transaction.TransactionManager implementation. I appreciate any help.
have you seen this article: https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/documents/a1-8-4/working with transactions in sap web application server java 6.40.article
It explains how to use transactions in your applications on Web AS 6.40.
Hope that helps!
