DFHWBERX uses the EXEC CICS WEB and DOCUMENT API commands to get information about the Web client's request and create and
send the error response.
DFHWBERX is used in the following circumstances:
- When it is configured in the Program setting in a URIMAP definition, if an error response is always wanted for the request.
- When the default analyzer program DFHWBAAX is set as the analyzer program on the TCPIPSERVICE definition, and no matching
URIMAP definition is found for a request. DFHWBAAX sets DFHWBERX as the application program using the wbra_server_program output parameter.
Refer to IBM's CICS Transaction Server documentation for more details of how DFHWBERX processes errors and recommendations
on how to use it.
