Thats true. But its not *me* thats adding the same appender multiple times.
It is the java plugin that executes the 'log4j.properties' file every time
the applet gets loaded. I as a programmer cannot control this.
An alternative could be to disable the default initialisation precedure and
expicitrly load 'log4j.properties' in the code afer cleaning up all
appenders (using resetConfiguration). But i prefer the default
initialisation procedure. If there exists a way to force a
resetConfiguration before executring the default initialisation, this would
solve my applet problems.
