All looks correct.

I meant that nobody on this list is going to write your software for you
unless you pay them. You can get help and tips, and maybe some working
code, but at some point, you're going to have to do the work yourself.

The Valve code is easy (and you probably already have it written,
compiled, and working). The hard part is designing the logging component
that you mentioned in your original post. This is what I meant by
"you're going to have to do the work yourself": you need to design your
own "logging object" that consumes log messages and does something with
them. We have no idea what that component should do and how it fits into
your architecture.

You seem to be asking for help to do something that is very unclear. I
can think of many ways to write logging statements to
files/databases/syslog/whatever but you've not really asked a specific
question.

You have basically asked "I want to write a logging valve, and I thought
I'd start by extending AccessLogValve. Anyone have any ideas?!". This is
not a very directed question. You aren't going to get very directed
feedback (at least not from me).

Posting your code would help. Describing what you think you might want
to do with your code would help.
