Hi,
Well my hope/idea was that I could log any kind of Object (that was serializable) and
then I could deside at JMS receiver side what to do with the logged object. Write it
to DB or something else determined by the object/class type.
But this doesn't seem to be possible. It looks like it would have to extend the
LoggingEvent class or put all information into the message (String) and then take it
out again on the receiving side. The first solution seemed somewhat more beautiful to
me.
