problem with alternative log4j.properties-file

[Paulicke Stephan \(KISP 53\)]

hi,
i wote a small application (contained in a .jar-file) which also
includes a log4j.properties file.
i also wrote my own logger which depends on org.apache.log4j.Logger
everthing works fine so far. i included a parameter to define an
alternative log4j.properties file
that should be used:
                                logProps.load(new
FileInputStream(logPropFile));
        
PropertyConfigurator.configure(logProps);
if i use this, the logfile will be empty. this was working before i
created my own logger.
any ideas?

thanx in advance
