Re: Programmatic Configuration of XMLSocketAppender

[Henry Chou <na...@gmail.com>]

"Nothing I've seen in the log4cxx codebase suggests that XMLSocketAppender
accepts a layout specification. "

I have also been digging through the XMLSocketAppender source files in
0.10.0, but couldn't find it; asking you guru's was my last resort. Weird
though... when using an xml config file with the appender,

>      <appender name="MyXmlAppenderFormated"
> class="org.apache.log4j.net.XMLSocketAppender">
>          <param name="Port" value="2222"/>
>          <param name="RemoteHost" value="192.168.1.101"/>
>          <param name="ReconnectionDelay" value="30000"/>
>          <param name="LocationInfo" value="true" />
>          <layout class="org.apache.log4j.PatternLayout">
>              <param name="ConversionPattern" value="%d [%p] - %m%n"/>
>          </layout>
>      </appender>


I get exactly the desired outcome: a pattern-based log message sent through
a socket. No "serialized LoggingEvent"'s, no XMLLayout logs; just the simple
"%d [%p] - %m%n" layout received from the server. Only when I
programmatically configure, that option is not obvious to configure (if
configurable at all).

Alrighty, *thank you*! I was hoping to eliminate the use of additional
(unnecessary) files, but I guess I'll have to keep the xml config file. And
thanks for the quick reply!

Best regards,
