By the way: I use the webstart version of chainsaw 2 since the binary 
version had problems finding the LogFilePatternReceiver and I didn't wanna 
go look for it... ;)

The LogFilePatternReceiver will do just that! The tailing functiononality is 
also very fast. I think it checks the file every 10 sec's by default. I have 
just got it to work for me. It was a bit tricky at first but then when i 
found out that the logging pattern was the problem it was solved easily. The 
logFormat in the chainsaw.xml (chainsaw config file) must correspond to the 
ConversionPattern for the logger...

Examples from my setup:

Chainsaw configuration file chainsaw.xml:
-------------------------------------------------------------------
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration >

<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/"
            debug="true">
   <plugin name="logFileReceiver" 
class="org.apache.log4j.varia.LogFilePatternReceiver">
    <param name="fileURL" value="file:///c:/logs/tit_log.log" />
    <param name="timestampFormat" value="yyyy-MM-d HH:mm:ss,SSS"/>
    <param name="logFormat" value="TIMESTAMP LEVEL [THREAD] CLASS 
(FILE:LINE) - MESSAGE"/>
    <param name="name" value="logfileReceiver" />
    <param name="tailing" value="true" />
   </plugin>
            <root>
                        <level value="debug" />
            </root>
</log4j:configuration>
-----------------------------------------------------------------------

Part of my log4j properties file:
-----------------------------------------------------------------------
log4j.rootLogger = DEBUG, appendingLogFile

log4j.appender.appendingLogFile=org.apache.log4j.FileAppender
log4j.appender.appendingLogFile.File=c:/logs/tit_log.log
log4j.appender.appendingLogFile.layout=org.apache.log4j.PatternLayout
log4j.appender.appendingLogFile.layout.ConversionPattern=%d %-5p [%t] %C{2} 
(%F:%L) - %m%n

-----------------------------------------------------------------------

Hope it helps!

//Anders
