code: public void setStandardSocketBindingPortExpression(String socketBindingName, String sysPropName, int port)
          throws Exception {
          setSocketBindingPortExpression(STANDARD_SOCKETS, socketBindingName, sysPropName, port);
      }
docs: Sets the port number for the named standard socket binding.
  If sysPropName is null, this simply sets the port number explicitly to the given port number.
  If sysPropName is not null, this sets the port to the expression "${sysPropName:port}".
  
  @param socketBindingName the name of the standard socket binding whose port is to be set
  @param sysPropName the name of the system property whose value is to be the port number
  @param port the default port number if the sysPropName is not defined
  @throws Exception any error
