From my application some times I print messages using System.out.println. These messages are being printed on Console and server.log in this format:

yyyy-mm-dd hh:mm:ss,SSS INFO [STDOUT] <message>

what I want is to print those messages in this format:

yyyy-mm-dd hh:mm:ss,SSS <message>

So basically only for those messages I want to use:

<param name="ConversionPattern" value="%d %m%n"/>

For all other messages, I want to continue to print in the default format specified in /conf/log4j.xml

How can I do that? I know for a fact that all my messages start with the following 5 characters: "PEND:" or "WEBF:".

Thanks
