Version 3 of TCLWS (Web Services for Tcl) as SAP Client

Updated 2015-05-27 16:48:00 by oehhar

HaO 2015-04-27: I am attacking the subject to write a more or less generic TCLWS Web Service client for SAP. This is my "progress report page", which might involve the next days when I progress.

Thanks to Gerald W. Lester for the great package !

Literature

This is the book I am using for reference: [L1 ]

Authentication

SAP has many authentication and transport security options. I tried HTTP Basic Authentication and no transport layer security.

Within this clt thread [L2 ], JMar wrote how to use basic authentication:

#-- http basic authentication
set authinfo [ base64::encode $szUsername:$szPassword ]
set httpHeader [ list Authorization "Basic $authinfo" ]

set szResponseDct [ ::WS::Client::DoCall $szServiceName myMethod $myRequest $httpHeader ] 

This worked out of the box.

WSDL File

The WSDL file delivered by SAP parses out of the box.

CALL

2015-05-27: So far, each call ended in a 'Variable missing' error from SAP. Passed arguments were not found by SAP.
