Since there have been some recent requests of the Log4J Appender that I have mentioned earlier, I now publish the current source for it here. Please don´t ask me of any documentation other than the one in the present source, because I don´t have any. The files are published under the GPL, so please respect that. The extra DominoUtils class is used to get a java.util.Properties object from a Domino View, and is used in the DominoConfigurator class.
You may want to take a look at my Log4LS project at Sourceforge. It is a simple port of the Log4J functionality into LotusScript.
