Character codeset conversion support for the Java Object Request Broker service

The CORBA/IIOP specification defines a framework for negotiation and conversion of character codesets used by the Java ORB service. WAS supports the framework and provides the following system properties for modifying the default settings...

com.ibm.CORBA.ORBCharEncoding Name of the native codeset that the ORB is to use for character data (referred to as NCS-C in the CORBA/IIOP specification). By default, the ORB uses UTF8. (In contrast, the default value for versions 3.5.x and 4.0.x of WAS was ISO8859_1, also known as Latin-1.) Valid codeset values for this property are shown in the table that follows this list; values that are valid only for ORBWCharDefault are indicated.

com.ibm.CORBA.ORBWCharDefault Specifies the default codeset that the ORB is to use for transmission of wide character data when no codeset for wide character data is found in the tagged component in the Interoperable Object Reference (IOR) or in the GIOP service context. If no codeset for wide character data is found and this property is not set, the ORB raises an exception, as specified in the CORBA specification. There is no default value set for this property. The only valid codeset values for this property are UCS2 or UTF16.

The CORBA codeset negotiation/conversion framework specifies the use of codeset registry IDs as defined in the Open Software Foundation (OSF) codeset registry. The ORB translates the Java file.encoding names shown in the following table to the corresponding OSF registry IDs. These IDs are then used by the ORB in the IOR Codeset tagged component and GIOP Codeset service context as specified in the CORBA/IIOP specification.
