That's a great example, but it does not help us folks strapped to 
Oracle 8i.  If I could somehow get a handle to the transaction, I 
could register a Synchronization to be called after a commit puts an 
empty_lob() in the DB as a locator.  I could then stream the content 
to the locator from my Synchronization.  This, of coarse, assumes that 
I am able to find the locator again, which does not seem hopeful given 
the limited context at this point.

Does anyone have any ideas here?
