WD ABAP SICF services

Under SICF if I find a WD ABAP service, how can I change it. Do I copy the service or is there a way to create the service?
Thanks
Mikie

What are you wanting to change? The security settings perhaps. It this is a customer created Web Dynpro ABAP application then you can edit the SICF service settings directly. However if this is an SAP delivered WDA, then you should create a serivce node alias for the node and change the alias to avoid having your changes overwritten in a futue updates.

Call a ABAP Web Service externally

Hi Experts,
I have a question on ABAP Web Service:
is it possible for Company A to call a ABAP Web Service from Company B externally? If yes, how would the it be done? How would the authority be controled? The calling of a Web Service externally, is there anything to do with XI?
Looking forward to your help!
Thanks!
Hua

Yes it is possible. It is possible with or without XI (based upon the WebAS release you are on). WebAS 640 has extensive functionality over WebAS620. Authority can be controlled in several different ways (HTTP authentication -Basic or HTTPS, Client Certificates, WebService Profiles).
There is lots of good on-line help and a sub-area of Web AS on SDN dedicated to Web Services where you can find many of your answers.
You can also check out my weblogs. I have written on the subject of ABAP WebServices without XI several times. There are real world examples from my compnay.
One thing that I might add is that that if you are going to call outside of your company's network you will likely have to configure the client proxy settings in transaction SICF.

Publish Abap Web Service in ICF virtual host

Hello
We have configured our abap aplication server with two virtual host in SICF
one the default_host that listen in http 8080 port and other virtual host that
listen in http 8090 port.
We need define some ABAP web services that listen in default_host:8080 and other virtual host in virtualhost2:8090.
We define de web service with SE80 wizard and then create the configuration end point
with SOAMANAGER.
Our problem is that soamanager ever create the entrie of endpoint in sicf transaction, under default_host:8080 service tree not under virtualhost2 service tree. and so we can not call
the web service like http://virtualhost2:8090/sap/bc.... because don't exist, only exist
http://defaul_host:8080/sap/bc....
we try to copy the entry of the tree under virtualhost2 in the proper place of the tree,
but when call the webservice with soaui the system report the error:
No Web service configuration for this access path: ""
i can see that there are entries in the table SRT_CFG_SRV_ASGN that are related with this
problem, because assign the url of the endpoint of the ws to virtual host, but i don't
know how the system generate this entries.
someone know how call ABAP web service with icf virtual host?
thanks
regards
diego

Hi Trevor
For test purpose i can do it works.
The key point is create the proper entry in the table SRT_CFG_SRV_ASGN that refer to the correct VIRTUAL_HOST.
When you genreate the endpoint of the service with soamanager, the system generate an entrty in this table with the fiel VIRTUAL_HOST = 0, you can copy this entry and change only two fields.
VIRTUAL_HOST = <the number of your virtual host>
HASH --> you can calculate this field with the FM CALCULATE_HASH_FOR_CHAR, in the parameter DATA contatenate the content of the fiels VIRTUAL_HOST and URL (be careful with the upercase), this function module return you the hash.
(First you have to replicate the icf tree that soamanager create under your virtual host tree)
With this configuration i can call to my WS over the virtaual host, using soaui.
I hope this can be useful for you.

diego

404 error while accessing sicf services via apache reverse proxy

Hi,
I set up an reverse proxy with apache 2.2 and try to access SICF Services via this proxy. I got the following error message from the sap system:
Service cannot be reached
The termination occurred in system SMP with error code 404 and for the reason Not found.
The selected virtual host was 0 .
What can I do?
Please select a valid URL.

When I access J2EE services via the proxy it works.
Is there any configuration which have to be done in the ABAP Stack for accessing Services via the proxy server?
For tests I tried to access the simple ping service ( /default_host/sap/public/ )
Thanks and best regards,
Tim

Hi Oliver,

ABAP Web service - Virtual Interface Not Found

Hi,
I have created a ABAP web service based on RFC. I changed the authentication to "Basic username/password" from SOAMANAGER. Also tested the web service from WSNAVIGATOR (of different portal) using WSDL url. Web service successfully returned response.
Now, I have a AJAX client where I have hardcoded the request (from wsnavigator) and trying to call this web service in SAP BW web template (from HTML/JavaScript). But its not giving error as "Virtual Interface Not Found". Also, i get 500 error. But the end point of the web service if looked up from browser gives response. The SICF service is active and upon tests gives valid response.
Found couple of discussions regarding this:
http://wiki.sdn.sap.com/wiki/display/VC/VirtualInterfacenotfounderror
But i'm not finding the setting to activate virtual interface in SE80. ALso, we have created many such web services and they used to work fine prior to upgrade to Ehp1 SP05 (BI) but the newly created web service is not working.
Any inputs?
Abhijeet

Hi can you please let me know how you resolved this issue?

ABAP web service security

hi guys,
we have a couple of abap web services here that are called by an external .NET application. Currently, the .NET application can call the web service without passing on any username and password. Hence, there is no security. I wanted to change it and make it secure, so in SICF, i selected my WS, logon data tab and changed the procedure to standard and left the u/p blank. Also, made sure that the WS definition in se80 is set to basic authentication and SOA Manager is also set to HTTP authentication - username and password. But the .NET application can still call the web service without passing on any username and password. I cleared out all the caches etc.
Any idea as to why .Net app is not getting prompted for u/p ??
thanks

Hi Anuja, to publish a web service without authentication you only have to configure the endpoint/service from transaction "SOAMANAGER" without marking any "Authentication Method" in the "Provider Security" tab.

How to consume the Abap web service in Java web-dynpro

Hi Everyone,
I want to consume ABAP web service in java web dynpro.
so when i tried to create model in java web-dynpro, it gave me an error message saying "Invalid WSDL or WSDL not found".
i think this error message is because, to access the WSDL of abap web-service, we need username and password, but the dialog box in java web-dynpro is not programmed to take username and password from us and send it to the server to get the WSDL.
i came to this conclusion because i was able to successfully test my abap web-service in java portal. the java portal asked me the username and password to open the WSDL.
So, please help me to consume the abap web service in java web-dynpro.
Thanks in advance
Regards
Vikas

Hi Vikas ,
while creating a model in web-dynpro try to use the "import web service model" option and if you are using local server choose the local server option so that you can get the available web services which are in server, select one among them and continue you process.I think this is the some what easy way .
If you want use the URL for wsdl better to once test the available service in server and copy that WSDL URL and paste over WSDL textbox.
I think this is pretty help ful to you

SSO and ABAP Web Services

I am opening this thread on behalf of my colleague Bala regarding SSO and ABAP Web Services.
We have gone through single sign on options and found several options are available within 5.0.
We would like to know the options available for SAP ABAP web services access from a Non-SAP system with user authorization but without Portal/ITS installation.
Also I would like to avoid any hard coding of user id in Non-SAP system .
Could you provide any information.
Thanks,
Bala

We have gone through single sign on options and found several options are available within 5.0.
Tell me what are the several options and what is your Non-SAP system?
without Portal/ITS installation.
ITS is now an integral part of ECC 5.0 system. So would not need a seperate installation, unlike earlier versions.

Issue regarding access of ABAP related services from portal

Dear All,
We need your input in the following issue:
Scenerio:
we have implemented ess 1.2 on ep7.0
here we have gone for "Enhanced Package 2" for TRAVEL for client requirements so Travel Services are ABAP WEBDYNPRO instead of Standard JAVA WEBDYNPRO and we have 2 transaction iviews on portal.
Now when an end user clicks on travel services, the request is forwaded to ABAP WAS. So, we need to maintain two entries in DNS: 1. Portal url, 2. ABAP WAS
Now the client doesnot want to maintain ABAP WAS entry in their dns. BUT if they do not maintain this than end users are not able to access ABAP related services...
Can you please suggest any possible solution for this issue.
Thanks & Regards,
JJ

Hi,
Per SAP Note 1040325, it says "It is not possible if there is another component between the browser and the message server (for example, a portal)." In your case a firewall between the portal and WAS. So a direct connection between the client and the WAS system is required which is a security risk. The section below gives more detail on why this is the case/
The following is a excerpt from the Portal "Network and Communication Security" guide:-
Please note that the requirement for direct access between the client and the backend is well flagged in the documentation. For instance, please refer to the Portal Security Guide, specifically the section "Network and Communication Security" (http://help.sap.com/saphelp_nw04s/helpdata/en/b9/c892f1ffc34156883ddd24aec01253/frameset.htm):
'Neither the portal nor the AS Java provides a proxy function. [...] If you have set up a network architecture with one or more firewalls, and your portal integrates iViews that initiate client-backend communication, you must set up access for the client through the firewalls to the application server in the back end.'
So the only secure solution is to install a webdispatcher in your DMZ and forward the requests from the (5) Portal to the (6) webdispatcher as in the graphic below :-
........................................./-> (3) Webdisp -\....................../-> (5) Portal
(1) Client (IE) -> (2) Firewall |.........................|-> (4) Firewall |
.........................................\-> (6) Webdisp -/......................\-> (7) WAS
The original requests bound for the (5) Portal are relayed via the (3) webdisp1 as you can only have one webdisp connecting to one backend SAP system (Portal OR WAS).
Hope this helps.
Michael

SICF Service not available in Production

Consuming ABAP Web Service in Non SAP system

Hi
I have created an ABAP web service form the RFC and configured it in the SOAMANAGER. I have tested it in Web Service Navigator using the URL and it is working fine.
Now I am trying to access it from the Non SAP system using Java Code. I am able to access the WSDL using the URL from the step 1 but not able to receive any output when providing inputs.
So I am not sure if I am missing any configuration on the Provider System (SAP) or on the Consumer system (Non SAP) to access the web service. As far I have not configured anything on the consumer system. Please let me know how to consume the web service in the Non SAP system.
Thank you,
Rohit

not necessarily an answer to your question, but i find that when creating SAP web services, before we create the code for consuming them, I always test them with the SOAPUI package. with this test suite you can import the WSDL, and run individual tests, seeing the input, output, exceptions, etc. This is a good way to check the connection, the flow and the service logic, before writing any code. This will also let you know whether it is a WS issue, or an issue with your code.
just a thought, from someone who has been there...
http://www.soapui.org is where you can find the SOAPUI. It helped me out a lot.

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..

ABAP Web Service client proxy - generation problems

Hi!
I tried to create an ABAP web service client proxy for many different web services -
for instance some of that listed at <a href="http://www.xmethods.net/">http://www.xmethods.net/</a> .
Almost on 99% of the WSDLs the client proxy generation failed.
For istance "<extension> not supported", or "<message...> must have at least one part",... .
Could anybody tell me what restrictions are to web services you can create a
ABAP client proxy for ?
In the SAP Web AS Java Stack there is no problem at all to generate a
client proxy for almost all of the xmethod-WebServices !
Is the ABAP Web Service proxy generation for production use ?

How to debug ABAP Web services from Microsoft Visual Studio

When developing .NET based Web services clients using Visual Studio that call Web services in SAP NetWeaver .NET developers would like to be able to debug inside SAP. In my blog <a href="/people/andre.fischer/blog/2007/02/07/how-to-debug-abap-web-services-from-microsoft-visual-studio to debug ABAP Web services from Microsoft Visual Studio</a> I would like to point .NET developers to the fact that SAP NetWeaver offers the option of external debugging to perform this task. Though the steps that have to be performed are described in the SAP Online Help I am sure that this option is not well known amongst the .NET developer community.

Hello WilliamIV,
>>How can I "configure" Visual Studio debugger to allow validation to work?
Since I do not have a VS2012 environment, according to your provided link, I created a test demo with VS2013, however, both ways catch the validation error:
If possible, you could have a try with VS2013 to see if it works or run the example on other machine with VS2012 to see if this is caused by the VS environment, in my side, I do not change any configuration, all are default.
If I misunderstood this issue, please feel free to let me know.
