Ideally, the code could be instrumented with logging/trace
calls that behaved appropriately (though perhaps differently)
under both svnserve and httpd. That may be exactly what you're
getting at.

My guess is that your complex Java application actually
has two logging facilities:
1.) Application-level audit-logging of things like "user
logged in", "user logged out", "user changed password", and
perhaps even "user ran report Foo with criteria Bar".
This probably gets logged in a database table (or tables)
in a structured or semi-structured way, and has all kinds
of application-level tools built around it.
If your application doesn't have this, it probably isn't
SOX compliant.
2.) log4j, for troubleshooting, monitoring, debugging,
tuning, etc.

log4j is great at (2), it's not-so-great at (1), especially
in environments where the audit trail is extremely important
(think SOX compliance).

I agree that for (2) it's usually a bad idea. For (1), it
is occasionally the least-evil solution.
