WSACONTEXT BUILD
Use the WSACONTEXT BUILD command to insert or replace WS-Addressing message addressing properties (MAPs) in the addressing context.
Description
Use the WSACONTEXT BUILD command for any of the following actions:- To insert or replace the Action or Message ID MAPs
- To insert or replace the To, From, ReplyTo, or FaultTo endpoint reference MAPs.
- To insert the RelatesTo MAPs.
You can use the command repeatedly to supply different data on each call, for example different endpoint references (EPRs). The MAPs are applied to all outbound SOAP messages created by the INVOKE SERVICE or INVOKE WEBSERVICE commands and to response SOAP messages from a service provider.
Options
- ACTION(data-value)
- Specifies an input value containing an Action MAP of the request
or response SOAP message; for example,
http://example.ibm.com/namespace/bookingInterface/MakeBooking. Actions are supplied in the WSDL or are calculated by the web services assistant, but can be overridden by this option. The data value must be 255 characters in length. If the Action MAP is less than 255 characters, you must pad the data value with trailing blanks. - CHANNEL(data-value)
- Specifies the name of the channel that holds
the addressing context. The name of the channel can be up to
16 characters in length. If the channel name is fewer than 16
characters, you must pad the data value with trailing blanks. If
you do not specify this option, the current channel is implied.
Acceptable characters for the channel name are A-Z a-z 0-9 $ @ # / % & ? ! : | " = , ; < > . - and _. Leading and embedded blank characters are not permitted. The accepted set of characters for channel names includes some characters that do not have the same representation in all EBCDIC code pages. It is therefore recommended that, if channels are to be shipped between regions, the characters used in naming them should be restricted to A-Z a-z 0-9 & : = , ; < > . - and _.
You can specify the channel name DFHTRANSACTION to use the transaction channel.
- EPRFIELD(cvda)
- Specifies the endpoint reference field. You can use this option
multiple times to build a full endpoint reference.
- ADDRESS
- The Address field of the endpoint reference is specified as a URI in the EPRFROM option.
- ALL
- A complete endpoint reference, described in XML, is specified in the EPRFROM option.
- METADATA
- The Metadata section of the endpoint reference, described in XML, is specified in the EPRFROM option.
- REFPARMS
- The ReferenceParameters section of the endpoint reference, described in XML, is specified in the EPRFROM option.
- EPRFROM(data-value)
- An input data value that contains a complete or partial endpoint reference that is to be placed in the addressing context. The EPRFIELD option describes what part of the endpoint reference is specified in this option by the application. The endpoint reference can be supplied by a web service application that uses the WSAEPR CREATE command or from another source, such as a service registry.
- EPRLENGTH(data-value)
- A fullword binary input data value used to contain the length of the supplied EPR.
- EPRTYPE(cvda)
- Specifies the type of EPR that is being built:
- TOEPR
- The destination EPR to which a SOAP message is sent.
- REPLYTOEPR
- An EPR to which a SOAP response message is returned.
- FAULTTOEPR
- An EPR to which a SOAP fault message is returned.
- FROMEPR
- An EPR that represents the sender of the SOAP message.
- FROMCCSID(data-value)
- Specifies the current Coded Character Set Identifier (CCSID) of
the character data to be put into the addressing context, as a fullword
binary number. If you want to specify an IANA name for the code page
or if you want to specify the CCSID as alphanumeric characters, use
the FROMCODEPAGE option instead.
For CICS® Transaction Server for z/OS® applications, the CCSID is typically an EBCDIC CCSID.
The default CCSID of the region is specified on the LOCALCCSID system initialization parameter.
For an explanation of CCSIDs, and a list of the CCSIDs supported by CICS, see CICS-supported conversions .
- FROMCODEPAGE(data-value)
- Specifies an IANA-registered alphanumeric charset name or a Coded
Character Set Identifier (CCSID) for the current code page of the
character data to be put into the addressing context, using up to
40 alphanumeric characters including appropriate punctuation. Use
this option instead of the CCSID option if you prefer to use an IANA-registered
charset name, as specified in the Content-Type header for an HTTP
request. CICS converts the
IANA name into a CCSID, and the subsequent data conversion process
is identical. Also use this option if you prefer to specify the CCSID
in alphanumeric characters, rather than as a fullword binary number.
Where an IANA name exists for a code page and CICS supports its use, the name is listed with the CCSID in CICS-supported conversions .
- MESSAGEID(data-value)
- Specifies a data value for a URI that uniquely identifies a SOAP message. The data value must be 255 characters in length. If the URI is less than 255 characters, you must pad the data area with trailing blanks.
- RELATESTYPE(data-value)
- Specifies a URI denoting the relationship type between the message to be sent and another message. The value must be 255 characters long. If the URI is less than 255 characters, you must pad the data value with trailing blanks. You are allowed to specify multiple RelatesTo MAPs. Subsequent calls of the RELATESTYPE and RELATESURI options create new RelatesTo MAPs.
- RELATESURI(data-value)
- Specifies a URI denoting the message ID of a message that the message to be sent is related to. The value must be 255 characters long. If the URI is less than 255 characters long, you must pad the data value with trailing blanks.
Conditions
- 123 CCSIDERR
- RESP2
values:
- 1
- The CCSID specified on the FROMCCSID option is outside the range of valid CCSID values.
- 2
- The CCSID specified on the FROMCCSID option and the CCSID of the addressing context are an unsupported combination.
- 4
- One or more characters could not be converted. Each unconverted character has been replaced by a blank in the converted data.
- 5
- There was an internal error in the code page conversion of the addressing context data.
- 6
- Either the text encoding is not compatible with the specified CCSID on the FROMCCSID option, or one or more characters are truncated.
- 122 CHANNELERR
- RESP2
values:
- 1
- The name specified for the CHANNEL option contains an illegal character or combination of characters.
- 2
- The specified channel was not located.
- 125 CODEPAGEERR
- RESP2
values:
- 1
- The code page specified on the FROMCODEPAGE option is not supported.
- 2
- The code page specified on the FROMCODEPAGE option and the CCSID of the addressing context are an unsupported combination.
- 4
- One or more characters could not be converted. Each unconverted character has been replaced by a blank in the converted data.
- 5
- There was an internal error in the code page conversion of a container.
- 6
- Either the text encoding is not compatible with the specified CCSID on the FROMCCSID option, or one or more characters are truncated.
- 16 INVREQ
- The INVREQ RESP2 values and the corresponding messages are shown below. For this command, if the EIBRESP2 value is > 100, the fullword EIBRESP2 field is regarded as a structure containing two halfwords. The low-order halfword always contains the error number. The high-order halfword contains the offset into the XML data where the parsing error occurred.
- 22 LENGERR
- RESP2 values:
- 20
- This condition occurs when the length of the stored data is greater than the value specified by the EPRLENGTH option. This condition only applies to the EPRINTO option and cannot occur with the EPRSET option.
