Cross language operation *never* worked with Java serialization, did it? It's not a new problem, is it?
I wonder how difficult it would be to *efficiently* transmit LoggingEvents over the wire, possibly in language neutral way.
Java's Object Serialization Stream Protocol is publicly available (http://java.sun.com/j2se/1.5.0/docs/guide/serialization/) as is the source for LoggingEvent. There is no technical reason that I can see why log4cxx and log4net could not mimic the serialization of log4j's LoggingEvent, however it would require some exploration and experimentation to get it right. I think the most complex aspect would likely be trying to mimic the serialization of Exceptions.
log4cxx isn't in a great spot to attempt it now since it does not use UTF-16 or LocationInfo objects in its LoggingEvent's, but that should be changing within the month. If it were to be done, it could be faster to get it working with log4net and then port the code to log4cxx.
