This figure shows how parameters that are passed to the weblogic.Server class in the startup command override the configuration MBean values that are otherwise set in the domain config.xml file. This figure shows the example of setting the server listen port. The config.xml file sets the listen port to 8010. However, he startup command includes the -Dweblogic.ListenPort=7501 option, which sets the listen port to 7501 instead.
