SimpleSocketServer error

[Nick Verma]

I am trying to run an example of log4j SimpleSocketServer to accept logging from remote clients. The properties file that I am using is:

log4j.rootLogger=DEBUG, x
log4j.appender.x=org.apache.log4j.net.SocketAppender
log4j.appender.x.RemoteHost=localhost
log4j.appender.x.Port=4445
log4j.appender.x.LocationInfo=true
log4j.appender.x.layout=org.apache.log4j.PatternLayout
log4j.appender.x.layout.ConversionPattern=[%d{MMM dd HH:mm:ss}] %-5p (%F:%L) - %m%n

While running I get the following error.

C:\logging-log4j-1.2.9\examples\chapter1>java org.apache.log4j.net.SimpleSocketS
erver 4445 log4j.properties
log4j:ERROR Could not connect to remote log4j server at [localhost]. We will try

Please advise where is the problem.
Thanks

That looks like the properties file the clients should use, not the server. The server configuration would more likely include something like a RollingFileAppender.

For example, here's a socket server's properties file from Ceki G�lc�'s The complete log4j manual (highly recommended):

# -------------------------------------------------------------------
# This config file is intended to be used by a SocketServer that logs
# events received from various clients on the console and to a file
# which is rolled over when appropriate. The interesting point to note
# is that it a configuration file like any other.
-------------------------------------------------------------------

log4j.debug=true

log4j.rootLogger=debug, CONSOLE, ROLL

log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d %-5p [%t] %c - %m%n

log4j.appender.ROLL=org.apache.log4j.RollingFileAppender
log4j.appender.ROLL.File=rolling.log
log4j.appender.ROLL.MaxFileSize=10KB
log4j.appender.ROLL.MaxBackupIndex=2
log4j.appender.ROLL.layout=org.apache.log4j.PatternLayout
log4j.appender.ROLL.layout.ConversionPattern=%d %-5p %c - %m%n
