Transaction id within a trigger

For some testing I'm doing, I need to be able to extract a reasonably unique
transaction id from within a trigger, an id that changes after a commit (or
rollback). I'm sending a .zip file containing the modified source classes to
your private address, only to prevent the file from being reflected to
everybody on the list. The base for the changes is a CVS sync done
yesterday. The changes themselves are fairly simple and are marked with an
RWS comment in the source:

 

o Add a long transactionId attribute to DatabaseConnection

o Increment the transaction id in the commit() and rollback() methods

o Modify the inner class in DatabaseConnection used by ProcedureConnection
with a getTransactionId() method that references its enclosing
DatabaseConnection

o Modify ProcedureConnection with a getTransactionId() method that a trigger
can use

 

I've tested this enough to be confident that there are no unfortunate
side-effects, so I'm offering the mods to you.
