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!

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.

Calling an Abap Web Service from IBM WebSphere with a MYSAPSSO2 Cookie

Hello,
I have the following problem :
I have to develop a proof of concept between IBM Web Sphere 5.1 and SAP AS JAVA 7.0.
I have created an IBM sevlet in Web Sphere, I use a specific redirect from an SAP AS Java to call it, this way I can have a SAP Logon Ticket, and I manage to call an ABAP module function with JCO with SSO.
Scenario 1 : browser + authentication --> AS Java redirect servlet MYSAPSSO2 cookie -> IBM WebSphere servlet JCO -> Abap module function (ECC5)
This scenario works fine.
I have to do the same scenario with a Web Service and I don't know what to do.
I try to use jax-rpc handlers but I don't know how to pass my cookie from my servlet to my handler.
Scenario 2 : browser + authentication --> AS Java redirect servlet MYSAPSSO2 cookie -> IBM WebSphere servlet JCO -> Abap Web Service (ECC5)
Has someone already done that ?
Regards, Julien.

Julien,
Why are you using 5.1....go for 6.0 and its cake walk, i have integrated WebSphere 6.0 with R/3 uysing xi.....in a week.
Scenario changed to:--
Browser+ authentication --> WebSphere AS servlet request --> XI --> RFC/bapi --> abap webService
Hope that helps

Calling an ABAP web service from a web dynpro

Hello,
I based my application on the: "Creating an E-Mail Client Using Web Dynpro's Adaptive Web Service Model" tutorial but when invoking the web service I get this type of error:
Exception on execution of web service with WSDL URL 'http://mySAPBackendServer:1080/sap/bc/soap/wsdl11?services=Z_MY_WEB_SERVICE&sap-client=XXX&sap-user=XXXX&sap-password=XXXX' with operation 'Z_MY_WEB_SERVICE' in interface '{urn:sap-com:document:sap:rfc:functions}Z_MY_WEB_SERVICEPortType'
Is this because I used Adaptive Web Service Model instead of Adaptive RFC Model? Or is it due to something else?
thanks a lot,
Tanguy Mezzano

The function module is remote-enabled, it is exposed thus as a web-service, I can retrieve it with webservicebrowser application.

I have tried to create a Web Dynpro with the RFC method to create the model but when I run and deploy I get a deployement error with:

Calling abap web service from webdynpro

hi,
i have a problem in that i am trying to call an ABAP web service published from r/3 in webdynpro. when i browse to the url generated by the r/3 application server it asks for my r/3 user name and password (not to be confused with http proxy user name and password). now when i enter it, i can see the generated wsdl without a problem. pressing escape gives me the standard 401 error.
please note this is the r/3 username and password which i am required to enter. when i try to get to the webservice in webdynpro. here is my code:
public void wdDoInit()
    //@@begin wdDoInit()
    try
          Request_YYMJ_WS_TEST1_DEF1_yymjServiceWebTest1 reekvesta = new Request_YYMJ_WS_TEST1_DEF1_yymjServiceWebTest1();
          reekvesta._setPassword("userid");
          reekvesta._setUser("password");
          wdContext.nodeRequest_YYMJ_WS_TEST1_DEF1_yymjServiceWebTest1().bind(reekvesta);
          wdContext.currentRequest_YYMJ_WS_TEST1_DEF1_yymjServiceWebTest1Element().setWfKunnr("0000000011");
          wdContext.currentRequest_YYMJ_WS_TEST1_DEF1_yymjServiceWebTest1Element().modelObject().execute();
          wdContext.nodeResponse().invalidate();
    catch(Exception e)
          IWDMessageManager msgMrg = wdThis.wdGetAPI().getComponent().getMessageManager();
          String msg = e.getLocalizedMessage();
          if ((msg==null) || (msg.length()==0))
               msg = e.getMessage();
          msgMrg.reportException(msg,true);
    //@@end
i have also tried it this way:
public void wdDoInit()
    //@@begin wdDoInit()
    try
          Request_YYMJ_WS_TEST1_DEF1_yymjServiceWebTest1 reekvesta = new Request_YYMJ_WS_TEST1_DEF1_yymjServiceWebTest1();
wdContext.nodeRequest_YYMJ_WS_TEST1_DEF1_yymjServiceWebTest1().bind(reekvesta);     wdContext.currentRequest_YYMJ_WS_TEST1_DEF1_yymjServiceWebTest1Element().modelObject()._setUser("userid");     wdContext.currentRequest_YYMJ_WS_TEST1_DEF1_yymjServiceWebTest1Element().modelObject()._setPassword("password");
wdContext.currentRequest_YYMJ_WS_TEST1_DEF1_yymjServiceWebTest1Element().setWfKunnr("0000000011");
wdContext.currentRequest_YYMJ_WS_TEST1_DEF1_yymjServiceWebTest1Element().modelObject().execute();
          wdContext.nodeResponse().invalidate();
    catch(Exception e)
          IWDMessageManager msgMrg = wdThis.wdGetAPI().getComponent().getMessageManager();
          String msg = e.getLocalizedMessage();
          if ((msg==null) || (msg.length()==0))
               msg = e.getMessage();
          msgMrg.reportException(msg,true);
    //@@end
in both instances i get the error:
Service call exception; nested exception is: com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeException: Invalid Response Code: (407) Proxy authorization required
please note
1. i am trying to test this on my local sap j2ee server, on my workstation. i am not deploying this as of yet to the portal.
2. i do have access to r/3.
3. the r/3 application server is in our corporate intranet, and therefore excluded from being looked up by our proxy.
4. our proxy DOES require a username and password. i added my user name and password to the webservice container section of the visual administrator, and excluded the r/3 server from the proxy list.
what am i missing?

Zafar,
Check the endpoint in generated WSDL. Probably there is a host name that is not in "exclude list" for proxy settings (like IP vs host name, or FQDN vs short host name).

Call ABAP Web Service with Java code only

Hi all,
First of all, I am writing script in Adobe form but am not using the one in SAP.
I am trying to call the web service and process the result with script open (i.e. no dataconnection created), because I am trying to do that in a dialog.
I can call a non-SAP web service without problem, but I am not able to call a simple web service with only a single string input, anyone have any example?
Here is the SOAP for input:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:sap-com:document:sap:rfc:functions">
 <soapenv:Header/>
 <soapenv:Body>
 <urn:Z_RFC_GET_STAFF_BANK_INFO>
 <A_STAFF_ID>0123456</A_STAFF_ID>
 </urn:Z_RFC_GET_STAFF_BANK_INFO>
 </soapenv:Body>
</soapenv:Envelope>
Here is my code to call:
 var cURL = "http://some-host-name:port/sap/bc/srt/wsdl/bndg_DEDB492BB032E7F1B09F001CC4FBCEC9/wsdl11/allinone/ws_policy/document?sap-client=300";
 var response = SOAP.request(
 cURL: cURL,
 oRequest: {
 "urn:sap-com:document:sap:rfc:functions:Z_RFC_GET_STAFF_BANK_INFO": {
 A_STAFF_ID: "0123456"

Hello I have the same problem, were you able to execute the WS through the JS code now?
I would like to call an ABAP WS using JavaScript to return complex structures that I would like to manage directly with JS.
I tried with this code and I get the error "RaiseError: Acrobat Raise." when the request is executed:
var WSUrl = "http://<server>:<port>/sap/bc/srt/wsdl/bndg_4D15C75529330AF1E10000000A150429/wsdl11/allinone/ws_policy/document?sap-client=500";
var VendorNumber = xfa.form.DATA.DATAFLOW.SF_HEADER.VENDOR_NUMBER.rawValue;
try {
// Create request structure, read Input out of text field
var request = {
 "urn:sap-com:document:sap:soap:functions:mc-style:ZWsTest" : {ILifnr: VendorNumber}
SOAP.wireDump = true;
// Call web service using SOAP object
var response = SOAP.request ({
 cURL: WSUrl,
 oRequest: request
// cAction: "urn:sap-com:document:sap:soap:functions:mc-style"
} catch (e) {
 xfa.host.messageBox(e.toString()); //pop-up "TypeError:service.CelsiusToFahrenheit is not a funciton"
with this other code I get the error "SOAPError: CX_ST_MATCH_ELEMENT:XSLT exception.System expected element 'ILifnr'":
try {
 var myProxy = SOAP.connect(WSUrl);
 var result = myProxy.ZWsTest( { ILifnr: VendorNumber } );
 xfa.form.DATA.DATAFLOW.SF_HEADER.E_DESCRIPTION.rawValue = result;
// Display the response in the console:
 console.println("Result is " + result);
} catch (e) {
 xfa.host.messageBox(e.toString()); //pop-up "TypeError:service.CelsiusToFahrenheit is not a funciton"
in the second option, if I make the field ILifnr optional the call is succesfully performed but the parameter is not passed to the WS. So the call is working.
Using stand-alone LiveCycle designer 8.1 and Adobe Reader 8
Any suggestions?
Many thanks,
G.

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.

ABAP Web Service with tables

Hello,
 
 
We need to build a web service with a predefined message in our ERP (ABAP), without PI or WebAS JAVA.
 
 
We thought it should be a simple task, because we had no problem with many other applications and systems when building the same service, but were not able to build it with SAP ABAP, probably as a consequence of our lack of knowledge on ABAP SOAP runtime.
 
 
We have an external asynchronous process that delivers information to many other systems using web services (information diffusion). Concecuently, the web service call's structure is determined by the caller, so we have to fulfill this structure if we want to receive the info.
 
 
The owner of the process defined a very simple service call, in which one kind of "record" can be repeated 1 to n times:
 
 
 
 
 
 
<reglasSuscripcion>
 
 <!Zero or more repetitions:>
 
 <nombre>?</nombre>
 
 <valor>?</valor>
 
 <nombre>?</nombre>
 
 <valor>?</valor>
 
 <nombre>?</nombre>
 
 <valor>?</valor>
 
 
 <nombre>?</nombre>
 
 <valor>?</valor>
 
</reglasSuscripcion>
 
 
 
In order to receive this info, we have to implement an abap web service handler to accept this kind of call, the same way other applications/systems have already done.
 
 
We tried to build a RFC function call and create a web service with the wizard and it resulted in a web service with the following WSDL:
 
 
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:sap-com:document:sap:soap:functions:mc-style">
 
 
 
 
 <reglasSuscripcion>
 
 <!Zero or more repetitions:>
 
 <item>
 
 <nombre>?</nombre>
 
 <valor>?</valor>
 
 </item>
 
 
 
 
<item>
 
 <nombre>?</nombre>
 
 <valor>?</valor>
 
 </item>
 
 </reglasSuscripcion>
 
 
 
 
We found two main problems:
 
 
1.- When "wrapping" the RFC as a WS with the wizard, for a table datatype it automatically includes the <item></item> tag, so we break the predefined calling rules.
 
 
2.- The namespace is fixed by the wizard, and we would like to use a common namespace for all the "susbscribers", logically, the namespace fixed by the information diffusion service.
 
 
We also tried to find info on the outside-in approach for building a web service from the WSDL, but all the info we found required the ESR and we have no PI, just the ERP.
 
 
Any ideas on how to proceed?
 
 
Thanks in advance,
 
 
Joseba M. Iturbe

#2. I've recently had to "zap" some namespaces in an ECC5 system because the calling (TIBCO) system didn't appreciate the default SAP "urn" default - something to do with multiple colons in the address. There were, I think, just three table this affected, all VEP* ones. I think I should have been able to change these via the virtual interface in SE80 except that the ECC5 code was a bit "light" in this respect, so you may be able to do this now in SOAMANAGER in ECC6 (btw, I also had to re-save the WS definition within WSCONFIG and re-activate the virtual interfaces after this "zap" to generated the associated handler class again).
#1. Given your "name / value" pairs represent a complex type, then it might be better practice to have them as "item" which is probably why SAP proposes it this way... what does your custom function module parameter list look like?

Proxying ABAP Web Service on NW CE

Hi,
Assume that we have a Web Service created in ABAP System and can be accessed anywhere.
We want to publish this web service to external 3rd party companies but don't want them to access directly SAP R/3 System.
One way is to create another Webservice on CE and call ABAP Web Service from there and also publish this CE Web Service.
But I remember that it is possible to create a Web Service Proxy on CE for anther Web Service.
Could you help me to choose the best option and also if there are sample solutions
regards

Hello,
I think you must create a Web Service proxy client and expose this client as a Web Service.
For creating your Web Service you must follow the outside-in approach:
1.Import the WSDL document from your ABAP system.
2.Generate the Java bean skeleton based on the imported WSDL.
This is the link to the help documentation: http://help.sap.com/saphelp_nwce10/helpdata/en/46/935a636110581de10000000a1553f7/frameset.htm

Debugging ABAP web services

Hello,
I have an ABAP web service created from a remote enabled function module. The web service is called from a BSP application. How can I debug the code within the function module?
I activated debugging for the web service in ICF. I set external breakpoint in the function module. However, the execution does not stop in the function module.
Any ideas?
thank you
Benolin

Hello,
I found a way to debug my ABAP code called from the web service.
I have an http connection configured in sm59 of type H. My proxy class uses this http destination to connect to the web service. Target host of this http destination is an application server of the R/3 system where my web service is available.
If I logon to the ABAP system to this particular application server and set breakpoints in my code, the execution stops at the breakpoints.

Calling a java web service from R/3 6.0

hi experts,
can anyone please tell me how to call a java web service from R/3 6.0?
i found some answers to this question but all those were for 6.4 or 6.2 but not for 6.0.
i want to generate a outbound flow from ERP system. so please tell me something about web service in that context.
Thanks in advance,
Sagar.

Hi!!!
I would do this scenario as a synchronous one:
[SAP R/3][ABAP proxy objects] <-> [XI]<->[SOAP Adapter]<--->[external java app]
In your ABAP transaction you will have to execute ABAP proxy method to send a message to XI. If it's not your transaction, you can use user-exit.
BTW, I have an experience with XI 2.0, not with 3.0, so I used a XI 2.0 terminology.

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.

Calling a soap web service from a java desktop application

Hi,
Does anyone know how to call a soap web service from a java desktop application? I've seen examples using Apache Axis, but it sounds like Axis needs to run on a web server and we are trying to avoid that. My initial thought was that, "of course we need a web server", but I'm wondering if there is a way to do this without a web server.
Any help is greatly appreciated.
thank you,
Julie

If you are the consumer you don't need any web server. The web server is only needed in the provider end.
In java 6 there is a built in framework to call web services without the need of third parties (such as apache axis)
take a look at:
https://jax-ws.dev.java.net/guide/Developing_client_application_with_locally_packaged_WSDL.html
http://java.sun.com/webservices/technologies/index.jsp
For the provider end there is also a built in http server to expose web service via HTTP without the need to
use any external web server.
take a look at:
http://java.sun.com/javase/6/docs/api/javax/xml/ws/Endpoint.html

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,

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..

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.
Regards
diego

Problem with ABAP Web service

Hello Experts,
Some unusual thing is happening.
Till this time my scenario was HTTP to RFC. So i have imported RFC in XI and its structure was perfact.
Tables having cardinality as 1...1, and fields were having cardinalities as 0....1.
Now we have planned to switch to the proxies and ABAP Web services. I have created the ABAP Web service with the same function module and imported it into the External definations.
When i am trying to use it into the mapping, Table cardinalities are 1....1 and fields are also having cardinalities as 1...1.
Now because of that i hv to map all the fields with some constants, but m not comfortable with it as there are nearly 1000 fields.
Do anyone of you have any idea what might be the problem? or how can i solve it.
Hope the question is clear.
Please help in this problem.
Thanks,
Hetal

Hello Hetal,
This is happening because when you genarte the Webservice out of a Function Module, all the fields in your are mendatory in the generated WSDL.
This can be avoided. The WSDL that you have generated for your webservice, can be manually edited in Stylus studio etc to change the cardinality and make it optional. We also did the same in one of our scenario and it is working fine.
As you are mapping these fields with constants, so it doen't make a difference if those are optional too.
Just edit the WSDL/xsd and reimport it.
Thanks
