2.4.1 XML Schema Built-In Simple Data Type Mapping

The following table shows the supported XML Schema Built-In Simple Data Type and the corresponding Oracle Tuxedo FML32 Field Data Type.

Table 2-3 Supported XML Schema Built-In Simple Data Type

XML Schema Built-In Simple Type	Oracle Tuxedo FML32 Field Data Type	C/C++ Primitive Type In Oracle Tuxedo Program	Note
xsd:byte	FLD_CHAR	char	-
xsd:unsignedByte	FLD_UCHAR	unsigned char	-
xsd:boolean	FLD_BOOL	char/bool	Value Pattern [ ‘T’ | ‘F’ ]
xsd:short	FLD_SHORT	short	-
xsd:unsignedShort	FLD_USHORT	unsigned short	-
xsd:int	FLD_LONG	long	-
xsd:unsignedInt	FLD_UINT	unsigned int	-
xsd:long	FLD_LONG	long	In a 32-bit Oracle Tuxedo program, the C primitive type long cannot represent all xsd:long valid value.
xsd:long	FLD_LLONG	long long	In a 32-bit Oracle Tuxedo program, the C primitive type long long can represent all xsd:long valid values.
xsd:unsignedLong	FLD_LONG	unsigned long	In a 32-bit Oracle Tuxedo program, the C primitive type unsigned long cannot represent all xsd:long valid value.
xsd:unsignedLong	FLD_ULONG	unsigned long long	In a 32-bit Oracle Tuxedo program, the C primitive type unsigned long can represent all xsd:unsignedLong valid values.
xsd:float	FLD_FLOAT	float	-
xsd:double	FLD_DOUBLE	double	-
xsd:string (and all xsd:string derived built-in type, such as xsd:token, xsd:Name, etc.)	FLD_STRING FLD_MBSTRING	char [ ] wchar_t [] (Null-terminated string)	xsd:string can be optionally mapped as FLD_STRING or FLD_MBSTRING using wsdlcvt
xsd:base64Binary	FLD_CARRAY	char[ ]	-
xsd:hexBinary	FLD_CARRAY	char [ ]	-
All other built-in data types (Data / Time related, decimal / Integer related, any URL, QName, NOTATION)	FLD_STRING	char [ ]	You should comply with the value pattern of the corresponding XML built-in data type. Otherwise, server-side Web service will reject the request.

The following samples demonstrate how to prepare data in a Oracle Tuxedo program for XML Schema Built-In Simple Types.

• XML Schema Built-In Type Sample - xsd:string
• XML Schema Built-In Type Sample - xsd:hexBinary
• XML Schema Built-In Type Sample - xsd:date

Table 2-4 XML Schema Built-In Type Sample - xsd:string

XML Schema Definition
-	<xsd:element name=”message” type=”xsd:string” />
Corresponding FML32 Field Definition (FLD_MBSTRING)
-	# Field_name Field_type Field_flag Field_comments message mbstring -
C Pseudo Code
-	FBFR32 * request; FLDLEN32 len, mbsize = 1024; char * msg, * mbmsg; msg = calloc( ... ); mbmsg = malloc(mbsize); ... strncpy(msg, “...”, len); /* The string is UTF-8 encoding */ Fmbpack32(“utf-8”, msg, len, mbmsg, &mbsize, 0); /* prepare mbstring*/ Fadd32( request, message, mbmsg, mbsize);

Table 2-5 XML Schema Built-In Type Sample - xsd:hexBinary

XML Schema Definition
-	<xsd:element name=”mem_snapshot” type=”xsd:hexBinary” />
Corresponding FML32 Field Definition (FLD_MBSTRING)
-	# Field_name Field_type Field_flag Field_comments mem_snapshot carray -
C Pseudo Code
-	FBFR32 * request; FLDLEN32 len; char * buf; buf = calloc( ... ); ... memcpy(buf, “...”, len); /* copy the original memory */ Fadd32( request, mem_snapshot, buf, len);

Table 2-6 XML Schema Built-In Type Sample - xsd:date

XML Schema Definition
-	<xsd:element name=”IssueDate” type=”xsd:date” />
Corresponding FML32 Field Definition (FLD_STRING)
-	# Field_name Field_type Field_flag Field_comments IssueDate string -
C Pseudo Code
-	FBFR32 * request; char date[32]; ... strcpy(date, “2007-06-04+8:00”); /* Set the date value correctly */ Fadd32( request, IssueDate, date, 0);
