Authentication while consuming a BAPI exposed as a web service

[Former Member]

Hi all,

This is the scenario - I am consuming a web service in my web dynpro application. The web service is nothing but a BAPI which is exposed as WS.

My query - how do I achieve authentication from the web dynpro application to the web service using SAP Logon ticket?

In NWDS, after I import the Web service and create a WS model, there's a node called 'Logical Ports'. In that node, I've set the authentication type in the security tab as 'Use SAP Logon Ticket'. But that doesn't work.Is there any other configuration to be made?

Also, immaterial of the type of authentication I specify(even if I specify 'no authentication'), only if I set the userid & password for accessing the backend in my code, does my application work!! Otherwise, it throws an authorization error!!

I'm struck with this issue for quite sometime. Have gone through help.sap links and also SAP docs. Most of the docs deal with either security for an RFC model or for a Web service project(EJB). I am not able to find a solution for my case.

Can somebody help me solve this?

Points assured.

Thanks & regards,

hi,

the authentication for the webservices could be set through ABAP.

In ABAP go to SICF tcode, find your web service over there,

double clicking it , will open the windo where u can set the logon procedure , security requirement etc.

hope it helps,

Hi Abhijeet,

Thanks for that answer. Can you please tell me where to navigate to change the logon procedure of the web service?

Thanks & regards,

go to the tcode SICF, navigate as follows,

default host->sap->bc->srt->rfc->sap

here you will find your web services , double click on the relevant ws and set the security or logon or basic authentication procedure over there...

hope it helps

Thanks Abhijeet.. But I was not able to find the web service there!!

I need to find the standard web services.(standard BAPIs exposed as web services).

Am using ECC6.0.

hi,

if you kno the web service name or have abstract idea about its name, then go to tcode WSCONFIG, search your web service over there through value help.

There it will give you the Access Address of your ws. Then access that using the path given (in WSCONFIG) from SICF tcode and then double click ws to set the security requirement.

hope it helps .

Hi all,

Solved the problem. I had to create a HTTP destination in Visual Admin and set the destination in my webdynpro implementation.

Then,I had to add a service reference tc_secwssec~service in the webdynpro project.

Hai,

You can Pass Authorizations to web service model before executing

wdContext.currentRequestXXX.modelObject()._setUserName();

wdContext.currentRequestXXX.modelObject()._setPassword();

wdContext.currentRequestXXX.modelObject().excecute();

Hi Naga Raju,

Kindly go through my post carefully. I do not want to pass the username/password. Instead I need to use Logon ticket.
