Subject: RE: SocketAppender questions
Using a 1.2.8 SocketAppender to talk to Chainsaw (1.3) has these
limitations:
no MDC
no LocationInfo
By the way, LocationInfo is created as a by-product of defining any
pattern layout that uses the fields provided by location info. So, if you
are writing to a FileAppender that uses these fields in the PatternLayout
as well as a SocketAppender for Chainsaw, be sure to specify the
SocketAppender first in the list of appenders.
One way to get LocationInfo in Chainsaw from a 1.2.8 client is to have
Chainsaw tail a log file that includes all of the LocationInfo fields in
its patternLayout, and use a LogFilePatternReceiver on the Chainsaw side
to parse and tail the file.

You are mixing 1.2.8 and 1.3 on the client and server side? This won't
work.

This was supposed to be fixed in 1.3.
