log4j.xml & Syslog

[nau10]

I've uncommented the syslog section in the log4j.xml file:







and added it to the section


<appender-ref ref="CONSOLE"/>
<appender-ref ref="FILE"/>
<appender-ref ref="SYSLOG"/>


However, when I startup the server, it bombs spectacularly.

Without the SYSLOG entries, it works just fine.

You only have to add





in your Syslog Appender and it works.

For all those who don't want to view source to see the solution, you need to add a layout element to the Syslog configuration. Just copy it from the file or the console appender config.
