Somewhere back on this same thread, I got the following answer from Yoav Shapira at
Millennium ChemInformatics
...
Have you considering the use of a mapped diagnostic context (MDC)? The
pattern would include %X{username} %X{applicationName}
%X{transactionName} etc. See the JavaDoc for the MDC class and the
manual for examples.
...
I haven't tried it yet, but at first look it would be exactly what we need...

I will also need such a jdbc appender since we have to
audit req/response messages along with certian user
info into a database.
It would be great if such a pattern mechansim is added
so that it will be easy to retieve the values and
store them into a database.
