Need GeronimoTransactionManagerLookup for hibernate 2.1.4.

When i googled i got some documentation to get the GeronimoTransactionManagerLookup.java for hibernate-3.2.jar.

I am using hibernate-2.1.4.jar, which has a different structure from that of 3.2.

hibernate jar has the following folder structure

in 2.1.4 is net/sf/hibernate
in 3.2 is org/hibernate

Can somebody give me an advice on how to get the GeronimoTransactionManagerLookup that is compatible with hibernate-2.1.4 jar.

I am able get the GeronimoTransactionManagerLookup as per the documentation available at the following link
