Calling Web Service of SAP R/3 in SAP PI

Dear Experts,
We have a Web Service in R/3 which is generated from the RFC(Function Module). We have consumed that in PI for some requirements where the application has no direct access to R/3.
But when we are calling the Service from PI, the result tables are coming blank. The same Web Service of R/3 is working in DOTNET application and getting the data.
There are no errors, the authorizations checks are through, but the data is coming blank.
Please help
thanks and regards,
Ravi Siddam

Ravi,
We have tried the same from SOAP UI client also and it is not working,
same result as PI. But I repeat the Service is working from DOTNET applications.
If it is not working in SOAP UI then it will not work in PI also. I suggest you to re-import the WSDL in you .net application and check.
Regards,
Ramesh

Yes, SAPHTTPA (runs on application server) and/or SAPHTTP (runs on front-end pc), one of which, is required for HTTP communication. So far, nothing too elaborate as far as SOAP goes, but the logic is simplistic. Here's some sample code:
DEST = 'SAPHTTPA'.
TRANSLATE HOST TO LOWER CASE.
MYURL = 'wssrvTest/Service.asmx/GetByOrderItem'.
CONCATENATE HOST MYURL INTO MYURL.
REQUEST_HEADERS-DATA =
              'Content-type: application/x-www-form-urlencoded'.
APPEND REQUEST_HEADERS.
CLEAR REQUEST_HEADERS.
*........Convert Order Number to External Format........................

       EXPORTING
            INPUT = ORDER
       IMPORTING

*........Convert Item Number to External Format.........................
CALL FUNCTION 'CONVERSION_EXIT_ALPHA_OUTPUT'
       EXPORTING
            INPUT = ITEM
       IMPORTING
            OUTPUT = ITEM.
*........Convert Material Number to External Format.....................

       EXPORTING
            INPUT = MATERIAL
       IMPORTING
            OUTPUT = MATERIAL.
CONCATENATE 'sOrder=' ORDER

How do i call web services from SAP ABAP

Hello,
Ian working with .net team. they are using sap .net Connector to connect SAP. But my job is In SAP side when Purchase Requisition is created, I have to call web services from ABAP and i have to pass the Purchase Requisition number to web service(.net Program). Please help me how to call web services from ABAP and how to pass value. Any one help me with example.
Thanks
RaviKumar

Hi Ravi,
If you can call EJB from ABAP and from EJB call Web service which you want to call. I am giving code to write in EJB business method processFunction.
public void processFunction(Function function) {
   IRepository repository;
   repository = new Repository("TestRepository");
   JCO.MetaData fmeta = new JCO.MetaData("ZTEST_EJB");
   fmeta.addInfo("REQUTEXT", JCO.TYPE_CHAR, 255,   0, 0,
   JCO.IMPORT_PARAMETER, null);
   fmeta.addInfo("ECHOTEXT", JCO.TYPE_CHAR, 255,   0, 0,
   JCO.EXPORT_PARAMETER, null);
   fmeta.addInfo("RESPTEXT", JCO.TYPE_CHAR, 255,   0, 0,
   JCO.EXPORT_PARAMETER, null);
   repository.addFunctionInterfaceToCache(fmeta);
   JCO.ParameterList input =
   function.getImportParameterList();
   JCO.ParameterList output =
   function.getExportParameterList();
   JCO.ParameterList tables =
   function.getTableParameterList();
if (function.getName().equals("ZTEST_EJB")) {
                    output.setValue(input.getCharArray("REQUTEXT"),"ECHOTEXT");
output.setValue("This is a response " + table.getString("E_NAME") +" " + output.getName(1), "RESPTEXT");
else if (function.getName().equals("STFC_STRUCTURE")) {
JCO.Structure sin = input.getStructure("IMPORTSTRUCT");
JCO.Structure sout = (JCO.Structure)sin.clone();
try {
      System.out.println(sin);
   catch (Exception ex) {
       System.out.println(ex);
                    output.setValue(sout,"ECHOSTRUCT");
output.setValue("This is a response from Example5.java","RESPTEXT");
}//if
Here REQUTEXT, ECHOTEXT are import parameter and RESPTEXT is the Export parameter of Function module ZTEST_EJB in SAP.
Here from this bisuness method you can call web service which you want and give back the result of webservice to ABAP F.M.

Bhavik

It is not possible to directly call a web service from SAP 4.6c.
Indeed, web service enablement is available as from Web AS 6.20, thus as from SAP R/3 4.7
So as described above, the solution is indeed to make use of PI(XI) for this.

Call a web service in an interactive form within SAP

hi experts
I need to call a Web service into an interactive form within SAP, but to do so fails to press on the button that calls the Web service, the strange thing is that if I keep the PDF in my PC, then open that PDF download button works correctly if I am doing something wrong?, you can do what I need?.
Greetings.

Hi asdasdasdasd1,
not sure if I fully understand your problem but it sounds like you are trying to execute your Web Service in the preview tab of LiveCycle Designer. When you do this, features of the Reader Extension Rights are not available so you will have to generate the form via the ADS and test the WS on the generated rendition as you have done.
Let me now if this helps.

Ben.

Calling Web Services between two SAP systems.

Hi Experts,
I am trying to trigger a web service created in one of the SAP system from a different R/3 system through WDA.
Kindly help me out on what are the configurations to be done like linking two systems (do i require this?) etc..
I have successfully obtained the WSDL file, but could not use it in my second system. It says , it encountered an error. I wonder if i am required to do any configurations.
All suggestions are welcome.
Thanks and Regards,
Anto.

Hi Antony,
By Proxy Object, I meant Class to consume WebService in your second system.
Lemme summarize, what you have done and lemme know where I am wrong.
System A.
You exposed an RFC enabled Func Module or BAPI as a webservice.
After this you have checked it using WSADMIN, and you have tested this as well.
And finally you saved the WSDL file of this Web Service.
System B.
you create a Proxy Object as specified in the link I provided.
you create the RFC destination n did the Logical Port Configuration as per that link.
Now you can use this proxy class any where , in any abap code.
you can use this in WDA as well.
But before doing so, I would suggest to write a test report as suggested in the link and test if your webservice is working fine.
Now please tell me where did you do the things differently.
Regards
Pushkar

Calling web Service from the Custom Adapter.Is it Possible?

Hi Experts,
I am having requirment in which i have to cal com.sap.aii.mapping.lookup.LookupService for calling web Service from the Custom Adapter.Is it Possible?
Regards,
Rajesh.D

Hi Rajesh..
Just looking the problem in another angle.. if there is no constraint that you have to use XI specific API to call the web service, why dont you use usual Java API used for calling a web service inside you custom adapter (I have Microsoft background.. donno exactly how it is done in Java,, but in .NET kind of a language it is possible). SInce your adapter is in Java itself and is capable of calling web service.. collect or lookup the data whatever you want and validate...
Just a thought..

How to call web service using J2SE 1.3?

Dear All,

i generate the ws proxy (jdev 10.1.3) and run it with wsclient_extended.jar (required JDK 1.4.1 or above??).
but one of my client say he has to use J2SE 1.3.x (as OS=AIX 4.3 that without J2SE
1.4.x ), could anyone tell me how can generate ws proxy (with supporting
library) for jdk 1.3.x?
if oracle don't have such library / tools, any third party tools / library available?

Hello,
I have found some Debug entries into my log file when this BPM process executes and go in Suspend mode. I do not understand the error. But this Begun entries have Green symbol which I understand there should not be any problem. But then why my process goes to Suspend mode??? If you like then I can also provide this Debug entry message from log file in order to get the idea about this problem.
I use Logical destination on automatic BPM step. Which has WSDL link. This wsdl link I have test into WS Navigator which works fine. But I am wondering why it is not working in my BPM process?????
does any one has idea what to do?

Problem call Web Service SAML on PI 7.0

Hi experts,
I have a problem very estrange on one scenario and maybe somebody could help me:
Our PI version is 7.0.
The BPM has got the following steps:
- Call WebService for get the SAML. Message Synchronous with request and response Authentification.
- We add the Authentification Response on Envelope message.
- Call web Service with Envelope, inside of this one there is the Authentification (step 1).
The las Web Service always returns that the Authentification is error.
We execute the same steps manually using SAOPGui program ( a free program for test WebService ) and the same steps works.. and the structures are the same, but on PI 7.0 never works.
We researh on forums and we have seen that the SAML Authentification is soported only for PI 7.1.
Could anybody confirm it? It is possible use SAML Authentification on PI 7.0? Are there other process to execute a SAML WebService using PI 7.0?
Any response or any idea will be very appreciated.
Thank you very much...
Regards,
Gemma

It is possible use SAML Authentification on PI 7.0?
at least the help section on 7.0 mentions the use of SAML...check this link
