Class org.omg.CORBA.ORB

java.lang.Object
   |
   +----org.omg.CORBA.ORB

public class ORB

extends Object

Standard Java CORBA Properties:

Property Name	Property Value
org.omg.CORBA.ORBClass	class name of an ORB implementation
org.omg.CORBA.ORBSingletonClass	class name of the ORB returned by init()

When creating an ORB instance, these values are located using a standard search order:

1. check in Applet parameter or application string array
2. check in properties parameter, if any
3. check in the System properties
4. fallback on a hardcoded default behavior
