Resolution: All files referred to are located in the attached file windows_event_log.zip.

1). Modify <TIBCO_HOME>\bw\5.9\lib\log4j.xml by adding new logger and appender . See the attached file log4j.xml.

----------------------
<appender name="NTEvent" class="org.apache.log4j.nt.NTEventLogAppender">
<param name="source" value="SomeServiceName" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%m%n" />
</layout>
</appender>

<logger name="bw.mylogger">
    <level value ="INFO"/>
    <appender-ref ref="NTEvent"/>
</logger>
----------------------

The logger and appender  were named “bw.mylogger” and “NTEvent” separately.

2). Download log4j from http://logging.apache.org/log4j/1.2/ .  Unzip the file and copy NTEventLogAppender.dll to %SYSTEMROOT%\SYSTEM32 .

Also attached is the file NTEventLogAppender.dll and we recommend you download yourself.

3). See the attached demo project.


Note: The default event ID is 4096. It appears there is no way to modify it. As an alternative, the Windows command “eventcreate” can be used along with "External Command" activity.
