How to configure port in Apache Chainsaw with Log4j2

Question

I got log4j2.xml that generates log files. Here is the config:

<Configuration status="INFO" advertiser="multicastdns">
    <Properties>
        <Property name="layout">%d | %-5p | [%t] | %c{2} | %M | %m%n
        </Property>
    </Properties>
    <Appenders>
        <RollingFile name="LogFile" fileName="${sys:user.home}/logs/webapp.log"
            filePattern="${sys:user.home}/logs/webapp-%d{yyyy-MM-dd}-%i.log"
            bufferedIO="false" advertiseURI="file:///C://users/bilguuna/logs/webapp.log"
            advertise="true">
            <PatternLayout pattern="${layout}" />
            <Policies>
                <TimeBasedTriggeringPolicy />
                <SizeBasedTriggeringPolicy size="1 MB" />
            </Policies>
            <DefaultRolloverStrategy max="10" />
        </RollingFile>
    </Appenders>
    <Loggers>
        <Root level="INFO">
            <AppenderRef ref="LogFile" level="INFO" />
        </Root>
    </Loggers>
</Configuration>

I'm able to see a log file using

file:///C://users/bilguuna/logs/webapp.log

on the browser.

A problem is that on the ZeroConf tab, my appender "LogFile" is appeared with Connection status "Connected". But when I double click on that row, it's just changed to disconnected/connected. When I check Chainsaw-log. It said that Connection refused as image below:

I guess it's because of that Chainsaw chooses 4555 as a default port which is not open on my machine. So what port should choose and how to set it in my log4j2.xml file?

Thanks

UPDATE: After I used the developer snapshot version as @Scott suggested, it seems like "connection refused" problem went away. But still I can't see the logs. When I click on entry at ZeroConf tab, it still changes the Connection Status to Connected/Not Connected. Here is the log from chainsaw-log tab:

Again, was I supposed to see the actual logs when I double click on entry at ZeroConf tab? Update: I got following exception on my console:

The problem is you need to use the latest developer snapshot of Chainsaw to work with log4j2. The webstart-runnable version works only with log4j1.

Developer snapshot is available at: http://home.apache.org/~sdeboy/
