TOPLink 3.6 in WebSphere 5

Question

Can anyone please help....
A client of mine is in the process of migrating from
IBM WebSphere V4 to V5...
They use TOPLink 3.6 and don't use CMP. However, they
do use the WebSphere external transaction controller
class:
TOPLink.Public.JTS.WebSphere.WebSphereJTSExternalTransactionController
server_.setExternalTransactionController(new WebSphereJTSExternalTransactionController());
They now get a class not found exception in WebSphere5
for:
com.ibm.ejs.jts.jts.Current - class not found
Assuming IBM has now removed this class from
WebSphere 5, is there a replacement WebSphereJTSExternalTransactionController
class for TOPLink 3.6 under WebSphere 5 ?
My client does not (yet) want to migrate to TOPLink 9 !!

Don,
Thanks for your help and for sending the source code
to TOPLink 9's WebSphereJTSExternalTransactionController class.
I changed the source for TOPLink 3.6's WebSphereJTSExternalTransactionController class..
Instead of this code:
org.omg.CosTransactions.Control control = Current.getCurrent().get_control()
I changed it to:
org.omg.CosTransactions.Control control = com.ibm.ejs.jts.jts.CurrentFactory.getCurrent().get_control();
It looks like IBM changed to a factory design pattern in
WAS 5 !!
I also had to make this change to TOPLink's
WebSphereJTSSynchronization class as well.
It was a bit of a 'bitch' to figure out the the ibm jar
files to include in my class path so I could compile
my changes, but once I did this, my client's TOPLink 3.6 now
works fine under WebSphere 5
