X.509 Web Service Authentication for ABAP AS Web Service Interaction

We are trying to use X.509 web service authentication with SAP Web AS ABAP between 2 different SAP installations. Company 1 is trying to consume a web service set up by Company 2.
Company 1 has installed Company 2's public key, generated the client proxy using Company 2's WSDL and created a corresponding lpconfig entry.
Then company 2 has set up the profile parameter ICM/HTTPS/verify_client to accept certificates and imported Company 1's SLL client certificate and mapped the user in USREXTID. Note that Company 1 uses self-signed certificates, so it does not have a root certificate, which is what the documentation says should be imported into the PSE instead of the SSL client certificate.
When Company 1 tries the web service call, it receives a request to authenticate the web service from Company 2. (basic authentication logon screen, even though the web service configuration is set to X.509 Client Certificate.
Should this work or is there a problem because Company 1 uses self-signed certificates or is there something else we are missing?

I think that the problem is in Service Authentication (in transaction sicf). You have to consume web-service, transmitting user-password for access.

Web based authentication for wired client, Crendentials submission failure.

Hi,
I am trying to set up the functionnality "cisco web based authentication" for the wired clients.
The problem i encountered is that my switch doesnt forward the client's password to the ACS.
When the user validate his credentials on the login page only the login seems to be forwarded.
The result of the command "show ip admission cache" always show the client in the init state.(i use the default cisco web login page).
the connection between aaa servers and the switch is working.
You will find in attachements the running-config and the debug file.
Thanks for your help, any ideas are welcome :) (its t os version c3750e-ipbasek9-mz.150-2.SE7).

Well i took a look on your documents but i didnt find anything that helped me ;S.
I'm still stucked on the same step.

Using Web Dynpro authentication for a Web Service call

Hi all,
I want to develop a Web Dynpro that calls a Web Service running on the same Web AS (7.0). The Web Dynpro will be integrated in a Portal. The web service that has to be called is automatically generated when we create a guided procedure :
http://help.sap.com/saphelp_nw2004s/helpdata/en/44/44c59fd7c72e84e10000000a155369/frameset.htm
In my Web Dynpro, I imported the WSDL of this WS and created a model.
The first time I tried to call the WS in my Web Dynpro I got an authentication error :
Service call exception; nested exception is: com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeException: Invalid Response Code: (401) Unauthorized. The requested URL was:"http://<myHostName>:50100/GPRuntimeFacadeWS/GPProcessExposing?style=document&pid=CA544E9B629A11DB91480017A48D672A&pver=0.5"
So I hard-coded an HTTP authentication :
     model._setUser("myWASuser");
     model._setPassword("myPassword");
And the Web Service call now works.
Now the next step is that the WS call is made by the user that runs the Web Dynpro. So I found this documentation :
http://help.sap.com/saphelp_nw04/helpdata/en/59/e8e95d1eba48dfa86ae91ad8816f5d/frameset.htm
It would resolve my authentication problem, AND the transport issue : at the moment the Web Service URL is stored in the Logical Port of the WD model, and at transport time, a rebuild of the WD project will be needed.
So I applied what is said in the doc : from the point of view of the Web Service consumer, I just had to add :
    model._setHTTPDestinationName("STARTGP");
(where STARTGP is the name of the destination I created in the Visual Administrator with a "Logon Ticket" authentication.)
before the execute(), and I removed my hardcoded authentication.
Unfortunately, nothing changes... I still get a 401 authentication error.
Does anyone have an idea about this ? Or maybe a workaround ?
Thanks in advance for any suggestion.
Regards,
Julien

Hello Julien,
I have a scenario similar to yours. A client webdynpro application accessing a EJB methods exposed as web service. Those EJB's methods calls R3 RFC's. The client requirements' was to allow SSO through all the layers (Webdynpro -> EJB WS -> RFC). The Webdynpro and EJB's are deployed on the same WAS.
Solution:
1 - Create a RFC Destination on Visual Administration provide the R3 connection parameters and set the Authentication for "Current User (Logon Ticket)". Save your Destination;
2 - In your EJB Project open your Web Service Configuration, on the Security page, set:
    Authentication Mechanism: HTTP Authentication
    Basic (username/password)
    Use SAP Logon Ticket
3 - In your EJB, implement the following code to create JCO Client for the RFC invocations:
Object obj = ctx.lookup(DestinationService.JNDI_KEY);
    DestinationService dstService = (DestinationService) obj;
    RFCDestination dst = (RFCDestination) dstService.getDestination("RFC", "<YOUR_RFC_DESTINATION_NAME>");
    Properties jcoProperties = dst.getJCoProperties();
    JCO.Client jcoClient = JCO.createClient(jcoProperties);
4 - In your EAR Project, open your "application-j2ee-engine.xml" and add the References:
     "tc/sec/destinations/service" as Service
     "tc/sec/destinations/interface" as Interface.
5 - Create your EAR File and Deploy;
6 - Check if the web service now requires Authentication: go to http://<host>:<port>/index.html and click on Web Services Navigator. Test your Web Service. Your Web Service should requiere you to log in before execute the test;
7 - Go back to your Visual Administrator and create a HTTP Destination. Provide your WS URL (should be something like "http://<host>:<port>/<WS_NAME>/Config1?style=document"). Choose Authentication: Logon Ticket. Save your Destination;
8 - Go to your webdynpro project, import your WS Model. (If you have already created it, you have to delete it and import it again, refer to this blog on how to reimport WS Models: /people/bertram.ganz/blog/2005/10/10/how-to-reimport-web-service-models-in-web-dynpro-for-java How To Reimport Web Service Models in Web Dynpro for Java );
9 - Open your model's Logical Ports node, go to the Security tab, and choose "Use SAP Logon Ticket";
10 - In your webdynpro code, before you call the ws invocation (should be something like that: <YOUR_NODE_DEFINITION>.modelObject().execute();), include the following line:
<YOUR_NODE_DEFINITION>.modelObject()._setHTTPDestinationName("<YOUR_HTTP_DESTINATION_NAME>");
11 - Save All Metadata and deploy your Webdynpro App. Test your results.
I hope it helps you, as the documentation on how to implement this scenario is scattered through the SDN and all the SAP help portal.
Best regards,
Paulo.

Web Service Model for ABAP Web Service

Hi,
I have developed ABAP web service and called it using web service model in WD. The WS is working from WSNavigator. While calling it from WD, im getting the following exception:
Service call exception; nested exception is:
com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeException: Invalid Response Code: (502) Proxy Error ( No data record is available ).
Is some setting required in R/3 where WS is created or on WAS where the WDAppl is deployed?
Regards,
Smruti

Hi Smruti,
Please try the following:
Go to Web Service model
Logical Port
Uncheck "Use HTTP Proxy" settings..
Also make sure the WAS has entry of R/3 in hosts files..

Webdynpro for ABAP versus Enterprise Services

Hi,
With ECC 6.0 the WebDynpro for ABAP will be available. After converting my well-known ABAP-dynpro screens to WebDynpro I will have the possibility to expose all R/3 functionality from within the portal.
Two years from now the Enterprise Services will be there. What will be the reason(s) for using enterprise services instead of WebDynpro for abap to make R/3 functionality available in the portal? I think at the end both functionalities can co-exist but what are the criteria to use one or both methods?
Greetings Theo

Theo,
This is not a discussion relegated to the bar...
First the short methodology is correct... Id the processes, expose major entry points as Services, orchestrate, publish Service Desc, endpoints, etc., repeat...
The real question remaining is, if I believe my entire process is incorporated with a single SAP system why would I expose Services (and add the additional layer)?
I agree with the comment where if a process completely executes in a single environment there is no need to change its strategy and force it to be an orchestrated set of Service interactions. That is not inconsistent with providing Service interfaces along the process so that it can be composed into other processes either not yet in place or requiring cross-system interaction. ESA is not saying "break open the container and make every little piece operate as Enterprise Services", instead it guides us to Service enable components so that others can consume them in a standard way, regardless of implementation / execution environment.
As we think about leveraging ESA for the benefit of our businesses (our enterprise and the ecosystem of business partners and customers) we have to acknowledge that we do not and will not know where every step of a busines process will execute throughout time. There may be tremendous value in executing part of a process that could be performed in that same SAP system in a completely different environment. The main benefit of Service enabling is business agility for a reasonable cost. I would argue that at least the main entry and exit points to major processes should have Service interfaces, followed by a more comprehensive assessment of internal process steps - looking for opportunities.
The other side of the equation is determining what additional consumers of the process could be found if major parts of the process exposed Service interfaces. To say, "my process executes inside this one system, so I should not expose it as a set of Services", ignores the potential benefit of other systems being able to incorporate that process in their execution (or parts of a process). As we expose more, well defined Services that represent aspects of enterprise business processes we create an environment where there is low cost, opportunistic integration based on standards.
Or put more briefly, make sure to execute your business process in an efficent computing manner, but do not let that constraint limit your thinking when it comes to Services. They are two different (yet related) issues. Services simply give us another way to leverage an asset we already have. Make the asset available and if it has value to the organization, it will be consumed.
Hope that helps...

How to generate a Web Service Proxy for an ESB Routing Service?

Hi,
I have a SOAP service behind an ESB Routing Service. I am aware that i can call this ESB Service at the SOAP endpoint which can be found at the ESB Console after registration.
But, i want to invoke this service using a Web Service Proxy. My understanding is that, i need to use the WSDL generated for the ESB Routing Service to generate the proxy. The WSDL which can be seen in JDeveloper does not have any soap bindings and hence the tool does not allow me to generate any proxy.
Also, the two WSDLs whose URLs can be found at the ESB Console do not have the soap endpoint properties.
Can someone help me out on the same?
Thanks and regards,
Priya.

Priya,
Just take the SOAP endpoint and suffix it with a ?wsdl
Even the Concrete WSDL endpoint should be having a SOAP endpoint.

Service billing for the material and service registers

Dear All,
I have doubt, if i do a sale of material 'X' and for the same material if i have to do a service invoice for rendering some service at the customer end. eg:- service charges for transportaion of the material to the customer place, doing installation charges for the material at the customer end etc.,
how should i go about it in SD .
A. Should i have to create a seperate mm master record for the list of service with the item category group LEIS
B. or is it possible to do a service invoice with out creating a sales order i.e directly based on the billing of the material 'x'
C. Is there any service tax register standard available. or if i wanted to create a service master should i have to ask the abaper to develop a z program for it
d. is this tcode can be used S_ALR_87012357 for service tax registers?
kindly update me on this
thanking you in advance
kumi

Hi
You need to create a material with item category group
a) LEIS (Service without Delivery) or
b) DIEN (Service with Delivery)
Based on the same you could bill the customer.
... Please.

Service accounts for the Workspace Database service permission Error while creating Tabular Mode from PowerPivot

Hi All,
Please help me out against this issue. I have spent so much (3 working days) time just figuring out what is the issue and its solution.
I am learning Tabular Mode and trying to create a mode based on PowerPivot model. I am getting following error message:
'The PowerPivot workbook could not be imported. The service account for the workspace database server does not have permission to read from the PowerPivot workbook.'
Here is my infrastructure:
1. SSAS in Tabular Mode is installed on my Windows 8 Laptop
2. PowerPivot is also in my laptop
3. There is only my account (as Admin of course) for SSAS
Here are my questions:
1. What is this error and how can I cope with that? A step by step explanation would be highly appreciated :-)
2. Do I need to change something in Windows settings or in SSAS?
3. I am confused about my workspace database server as well, Do I have to install SSAS twice; one for development and one for workspace?
Looking forward for the expert advise.
Tahir
Thanks, TA

Hi,
I suspect you might have more luck if you try the SSAS forum: http://social.msdn.microsoft.com/Forums/sqlserver/en-US/home?forum=sqlanalysisservices

FAQ : BlackBerry Web Signals Technology for Third Party Content Services

hi,
back in October, 2008, RIM announced the new Web Signals technology
the official Press Release is here :
http://supportforums.blackberry.com/rim/board/message?board.id=Hello&thread.id=56&jump=true
The following is my understanding of the Web Signals technology.
Get information : state of the art
To this day, users who want to get updated have many ways:
going on the website and look at the News page
subscribing to a newsletter and have notifications sent by email that stacks in regular mail flow of information
using an RSS feed (inside the BlackBerry Browser, or using a dedicated application like Viigo)
Why a new thing?
All these information channels are standard and have been used for years, but all these were not using the abilities of the BlackBerry technologies. So the idea was to create a new channel that would be pushed directly from server-side, but to a cool location.
So what is exactly? For the layman?
Web Signals is basically an icon on your home screen, with a little indicator so show when there are new things. It's the same indicator as on the Messages icon and the SMS icon.
How does it work?
you go on website that has created a web signal, and subscribe to it. It is usually free. The icon then appears on your Home Screen.
FAQs
1) seems like installing a Web Signal on BES is influenced by the IT policy. If you cannot install Themes or Applications, you can't install Web Signals
2) unsubscribing to Web Signals is easy but you must know how. You just have to go to the following page, using your BlackBerry device: http://push.na.blackberry.com/mss/PM_subList
3) you can move the Web Signals icon just like any other static icon on your Home Screen.

But do please keep in mind that security is a 2-way street...the human element play an equal part in that security, and you have failed at that in this situation, yet desire for the automated methods to still recover for you. Such just isn't possible, because your failure has exceeded the capabilities of the automated methods.

Integrate Function module in Web Dyn Pro for Abap

Dear Experts,
Im new to WDA, i want to integrate function module (which will display the smartform) in webdynpro abap.
is there any option to do that?
With Regards,
P.Arun
Edited by: Arun Padmanaban on May 27, 2009 12:30 PM

Dear Arun,
you can call the function module it is as same as how you call from abap editor.
or else instead of smart form you can call adobe form.
WD works with adobe forms to integrate smart form i am also not sure.
to work with adobe forms just search in this forum you will get lot of links.
or check this link to displaying a smartform in pdf format using webdynpro

Service Items for Line Type as Service

I have created a new line type in purchasing as 'Service'. The Value Basis is 'Amount' and Purchasing Basis is 'Services'. Now when I am trying to create a PO for this line type, the Item field is non updateable. I cannot search for any items.
Can I not create and select items for this line type?

Hi,
This seems to be the current functionality. Instead of choosing the item, you can fill the category and description.
If you are trying to treat your purchasable services as item, than try using line type with similar setting as Goods
Thanks

Can you run multiple Excel Services Applications against a single Web Application?

I have been struggling with this one for a while now, hopefully someone can help me understand what I am missing...
I have a single SharePoint Farm. This farm runs multiple Web Applications & the Service Applications.
1. SharePoint Only Server with Multiple Site Collections (http://sharepoint.com/...)
2. MS Project Server with Multiple Site Collections (http://pwa.com/...)
3. My services applications all exist on the same farm.
I was under the impression, and believe that I validated this through testing and from this site (http://blogs.office.com/2009/11/16/excel-services-in-sharepoint-2010-administration-improvements),
that you can only run a single Excel Services Application against each unique Web Application. In essence, I can run one Excel Services Application against the SharePoint Only Server, and another Excel Services Application against the MS Project
Server... However, I can NOT run multiple Excel Services Applications against the different Site Collections within the MS Project Server becuase it is only aware of its "default" Excel Service Application.
ie. I can NOT do the following: ExcelServiceApp1 for
http://pwa.com/SiteA & ExcelServiceApp2 for
http://pwa.com/SiteB
Is that correct?
If that is not correct, then I must be missing a way to specify a different Excel Service App for each Project Web App Site.
Some other solutions that I think may work, but would really appreciate if someone could validate:
- Create multiple Project Server Service Applications for each instance of PWA/Excel Service? (but wouldn't this still have to use one of the two WebApplications and cause the same limitation?)
- Create a new Web Applciation for each PWA/Excel Service? (ie.
http://pwasite1.com;
http://pwasite2.com; http://pwasite3.com, etc.)
Thoughts/suggestions are very greatly appreciated!!!

Hello Trpy2k
I have not done what you are doing and I assume that you are using project server 2010. However, you answer lives in PowerShell.
The New-WebServiceProxy show that you can create a new proxy by spacing a URL and not a web application. The default proxy from the web application is directing to the default excel service. If you need another excel service, you must specify another
proxy and this may do it for you.
Also, don't forget the Secure State service and that each excel report will need this configured, that is with the assumption that the other excel service requires different authentication.
PS. This question may get a better answer in the SharePoint forums.
Cheers!

What is used for WebDynpro for ABAP?

hi all friends,,
what is used for WebDynpro for ABAP?
Thanks,

Hi
Web Dynpro for ABAP - Getting Started
Web Dynpro for ABAP is SAPs new standard UI technology for developing user interfaces in the ABAP environment. In the long term Web Dynpro for ABAP will be the successor of the traditional screen (Dynpro) based user interface technology which is based on the SAP GUI. Available with NetWeaver 7.0 (2004s) Web Dynpro for ABAP provides the same declarative UI development paradigm as Web Dynpro for Java directly out of the NetWeaver ABAP Application Server. Web Dynpro for ABAP allows the development of user interfaces directly within the ABAP Workbench (SE80) and the Web Dynpro runtime environment is a central part of the ABAP server and can be used in any SAP solution based on NetWeaver 7.0 (2004s) without the need of an additional server installation.
Web Dynpro for ABAP allows the development of user interfaces in a declarative way by providing a mighty framework which abstracts the rendering technology from the core UI definition tasks. The Web Dynpro developer declares the layout and behavior of the UI without caring about HTML, JavaScript, browser specifics or the HTTP protocol. Instead the focus lies on designing graphically Web Dynpro components based on the Model View Controller model, which enforces a clear separation between the UI layer and the underlying business logic.
This declarative Web Dynpro programming model enforces the developer to focus on the tasks of
Designing the layout of the visible views (where should the table be placed, do I need tabs, how should the button look?)
Declaring the flow and behavior of the application (flow between views, which event is triggered by which button click, etc)
Defining the data binding (which internal table is displayed in a specific table, etc)
Implementing the event handlers and controller methods.
Without making any assumption about the used rendering technology, like which browser should be supported or if the Web Dynpro application will be later displayed in a web browser via HTML at all or in another kind of client with completely different rendering capabilities.
The Web Dynpro Frameworks provides all important UI features directly out of the box:
All elements (tables, buttons, trees, dropdown list boxes, etc) necessary for state of the art user interfaces are provided by the Web Dynpro Framework in the form of predefined UI element libraries.
Complex features and behavior of UI elements.
Internationalization of the UI. All visible strings in a Web Dynpro ABAP UI are handled by the translation system and are translated in the same translation environment like other ABAP language dependent resources. All texts are displayed automatically at runtime, dependent of the users credentials.
Accessibility features are directly built into the framework and UI elements.
A unified rendering engine generates at runtime the data which is sent to the specific client application, which is not limited to browsers but includes the NetWeaver Business Client.
All this is available in the established environment of the ABAP application server and well known capabilities like the transportation and change management system, security environment, test and performance analysis tools or remote debugging can be used like in common ABAP development.
