Has anyone tried the latest WebSphereExtendedJTATransactionLookup? I'm Having a problem hooking the WebSphereExtendedJTATransactionLookup into Websphere 6.0 for CMT participation. I'm wondering what the proper configuration should be to support the new WebSphereExtendedJTATransactionLookup.
Any help is appreciated.

Hibernate version:
Hibernate 3.0 beta1 w/ latest src download from sourceforge for WebSphereExtendedJTATransactionLookup

Mapping documents:
in hibernate.cfg.xml
<property name="hibernate.transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</property>
<property name="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.WebSphereExtendedJTATransactionLookup</property>


Full stack trace of any exception that occurs:
Either a NamingException from the JTATransaction when the WebSphereExtendedJTATransactionLookup has
public String getUserTransactionName() {
return "java:comp/UserTransaction";
}
-or -
A ClassCastException from JTATransaction if WebSphereExtendedJTATransactionLookup has
public String getUserTransactionName() {
return "java:comp/websphere/ExtendedJTATransaction";
}

Put that to JIRA please.
Websphere is a mess

I see there is a Websphere transaction management issue...HB-1354...I've added my findings to the comments.

I've done some further research. The ExtendedJTA... API for WAS 6.0 contains different methods than that of 5.1. I've developed what I believe are the appropriate fixes and would be happy to provide them. To whom should I provide this information?

Attatch it to the JIRA issue please.
