We often use this configuration file in the program:
Listener = org.kyle.net.svr.sample.sampleListenerImpl
ServerAddress = 127.0.0.1
ListeningPort = 80
Listenertimeout = 120
STATELESSSERVICE = TRUE
Loglevel = all
LogPath = Server.log
A source code for processing such a configuration file here is provided here.

Instructions:
String cfgfile = "server.cfg";
GenProfile M_ENV = New Genprofile (cfgfile);
This allows for, for example, M_env. GetServeradDress (), etc., can be used in the program to obtain the corresponding content of the configuration file.
