Hi Gautam,

This has helped me a lot. I had posted a similar question a month back (on
30/9/02 with subject :SocketAppender help required).
Today I've got my answer. Thanx a ton to you.

Problem)


Hello Thomas,

Found the problem. It is in SocketAppender. The SocketAppender uses 
an option called "LocationInfo" which defaults to "false". As a 
result, the LoggingEvent object written to the socket does not 
contain any location information. That is, it does not contain a 
reference to a "LocationInfo" object. Hence, no location information.

Add  the following to your log4j configuration for the client (the 
classes logging to the ServerSocket) :

log4j.appender.socketserver.LocationInfo=true

When you are done, your configuration file should have the following:

log4j.appender.socketserver = org.apache.log4j.net.SocketAppender
log4j.appender.socketserver.RemoteHost = 127.0.0.1
log4j.appender.socketserver.Port = 8889
log4j.appender.socketserver.LocationInfo=true

This is not mentioned anywhere in the documentation (at least I 
couldn't locate anything). The JavaDoc for SocketAppender does 
mention the following:

"getLocationInfo() 
          Returns value of the LocationInfo option
          
setLocationInfo(boolean locationInfo) 
          The LocationInfo option takes a boolean value. "

Hope this helps.

Regards,

Gautam Satpathy
