public class NumberGenerator
extends AbstractNumberGenerator
implements NumberGeneratorIF, java.lang.Runnable

The CORBA File Server.

Property Keyword	Datatype	Default	Description
NameServiceName	String	NameService	The name of the requested CORBA Name Service. This value is an application property.
NameServicePort	String	2809	The port number of the requested CORBA Name Service. This value is an application property.
NameServiceHost	String	localhost	The host name of the requested CORBA Name Service. This value is an application property.
CORBAProtocol	String	""	The CORBA protocol in the corbaloc (CORBA locator) to find the name service. The default of CORBA is iiop, which is identical with an empty string "". For IIOP over SSL the protocol must be ssliop. This value is an application property. It is ignored if ORBInitRef is set.
ORBInitRef	String	none	The full corbaloc (CORBA locator). If this value is set, the values of NameServiceName, NameServicePort, NameServiceHost and CORBAProtocol are ignored. This value is an application property. Example: NameService=corbaloc::1.2@MyServiceHost:MyServicePort/NameService
ORBProperty[???]	String	null	An ORB property. The property name of the property is defined in the brackets. Example: ORBProperty[com.sun.CORBA.codeset.charsets]=0x05010001, 0x00010109 ORBProperty[com.sun.CORBA.codeset.wcharsets]=0x00010109, 0x05010001
ServiceName	String	NumberGenerator	The service to be used by the service. This value is an application property.
PrintNameServiceIOR	boolean	false	This flags tells the server to print the NameService IOR to the console. This IOR can be used by the client to find the name service used by service.
NameServiceContext	string	"com/highqsoft/"	This property set the name service context. The name service context is the context in which servicename will be published. The conext must ends with '/' character.
DebugLevel	int	none	To get verbose output set this value. Currently there is no convention at what is printed at what level.
StdOut	File	none	The name of a file that service uses as standard output stream. This value can not set via a property files (parameter Properties), because it will be used directly after startup and before the property file is evaluated.
StdErr	File	none	The name of a file that service uses as standard error stream. This value can not set via a property files (parameter Properties), because it will be used directly after startup and before the property file is evaluated.
ConfigFile	XML File	none / required	The name of the XML configuration file.
Properties	filename	none	A file that contains the properties. The properties defined directly as parameters have higher priority.
