Rendered Message in JMSAppender messages

["FLYNN, Peter -Syntegra UK" <Pe...@syntegra.com>]

Hi,

Here is my configuration (in XML) of my JMS Appender:

<appender name="JMS" class="org.apache.log4j.net.JMSAppender">
   <param name="TopicConnectionFactoryBindingName"
value="cn=LoggingTopicConnectionFactory"/>
   <param name="TopicBindingName" value="cn=LoggingTopic"/>
   <param name="Threshold" value="DEBUG"/>
   <layout class="org.apache.log4j.PatternLayout">
     <param name="ConversionPattern" value="[%-5p] [%d{DATE}] [%C.%M] -
%m%n"/>
   </layout>
</appender>

As you can see I'm using PatternLayout.  The message is sent out onto JMS as
a serialised java object (org.apache.log4j.spi.LoggingEvent) wrapped in an
javax.jms.ObjectMessage.

On the class org.apache.log4j.spi.LoggingEvent, I can use methods
getMessage() and getRenderedMessage().  

Both return the %m message string, but I would expect getRenderedMessage()
to return the rendered message as defined in the layout in the
configuration.  

Is this a bug, as the message should have been rendered before sending the
message out on the JMS appender?

Regards,
Peter

Message rendering is done prior to serialization. After serialization 
calling getMessage and getRenderedMessage always give the same result 
regardless of how you configure the server (receiving) side. Object 
rendering should be configured on the clients. HTH,
