Execution of BAPI Webservice from webdynpro

Hi
We have a BAPI called CreateUser in backend system and this standard BAPI is exposed as a webservice and not published in ESR or UDDI. Just we have  wsdl.
I want to develope a WD4J application to execute the BAPI Webservice.
Can any body please tell me what is the right procedure i.e Is we need to use LOGICAL DESTINATIONS
(or ) Any configurations required between Java Stack and ABAP Stack.
I am using Adaptive webservice model. I am getting some errors if i import the model using wsdl only.
Please any body give me the step by step procedure in CE environment .
Regards
Kalyan

Hi,
documentation about proxy generation from RFCs/BAPIs is available at: http://help.sap.com/saphelp_nw04/helpdata/en/ed/897483ea5011d6b2e800508b6b8a93/frameset.htm
There's a tutorial how to bind a Web Service to a WD model at: https://www.sdn.sap.com/sdn/developerareas/webdynpro.sdn?page=TutWD7_CarRentalWS.htm
I'm not sure if this tutorial includes the Web Service generation also, but you can search for this in the online documentation of the Developer Studio.

  • Consuming PI Webservice from Webdynpro Java Not working

    Hello SAP,
    Environment: CE 7.2.
    Resolution expected immediately, Helpful answer is highly appreciated.
    Is the namespace should not exceed 60char for PI Webservice, for executing the webservice from Webdynpro Java.
    I tried with all the options in executing the PI Service from Webdynpro Java, None of the options worked. I am facing the below error while I was calling the PI Webservice.
    I don't see any problem from Webdynpro Java, what ever the procedure I have followed is the standard procedure.
    Fortunately when I execute the service from Webservice Navigator, it is working as expected. The same webservice when I consume it from Webdynpro Java it is not working
    Options tried so far:
    1) Published the Services to Service Registry and there by consuming the PI Service from Service Registry - Not worked
    2) Tweaked the URL with few options - Not worked (Tweaking the URL, ex: portType, Binding)
    3) Changing the Business Systems in PI and there after calling the service - Not worked
    4) Initializing the code, instead of creating Service Controller and calling the PI Service - Not worked.
    5) Created a Provider System and tried to call the PI Webservice from Provider System - Not Worked
    For all the Options, I am facing the same error which is provided in the screenshot.
    Below procedure which I have followed for calling the PI Webservice:
    1) Created Adaptive Webservice Model
    2) Provided PI Webservice URL (It prompts for PI System UserId and Password)
    3) Selected Option - No Service Group Configuration
    4) Provided Logical Destination
    6) Completed creation of Model
    7) Added the model as a UsedModel
    8) Right Click on Comp Contr. and selected Apply Template and Created a ServiceController for the model (Entire mapping to comp contr, Initializing the nodes is taken care by Service Contr.)
    9) Created an Template Action button and there by calling execute method which is auto rendered from CompContr..
    10) Build the project.
    11) Activated the code and Run the Application.
    12) Getting the below error which is showed in the message.
    ERROR MESSAGE:
    Exception on execution of web service on destination 'GetPIHRPeopleData' for operation 'SI_CreateHRPeopleData_OS' in interface 'SI_CreatePeopleCompany_OS'

    Hi Sankar,
    If the webservice is working fine in the Wsnavigator then there is some problem with importing the webservice in webdynpro for Java. Please check the required parameter for creating the Adaptive Webservice Model. After adding in the used model and compoent controller binding, you need to write code for to execute the webservice model.
    Please check the code for initialization and execution for the webservice and then test it.
    Best Regards,
    Arun Jaiswal

  • Geeting exception while executing BPM webservice from webdynpro.

    I have created a webservice to start BPM process.
    If I am testing from webservice navigator it works fine and BPM task gets created in my UWL. But when I execute this webservice from webdynpro I get the below error
    Exception on execution of web service with WSDL URL 'http://pepu56:50000/bpm/demosapcom/lngtranslationprocess/StartService?wsdl' with operation 'NewOperation' in interface 'TranslateBPMWSDLFile'
    Please note that : I have deleted the output part from both binding and PortType section of this webservice.

    I was doing a silly mistake. I was not running my webdynpro application from portal. I was running my application through "Deploy new archive and run" option.
    I got this clue to run this app after login into portal from the fact that when I was running webservice from WSNavigator I was prompted to pass user credential to execute this service.  I had not given any authentication option while creating web service, so just guessed if I run it from portal my user credentials might be taken. And it worked for me.
    I really don't know why I was asked for user credentials in WSNavigator and how my user credentils would have taken when I ran this app from portal. But this is how I am not getting this error.

  • How to call a webService from WebDynPro ABAP ?

    We are trying to call a webService from WebDynPro-ABAP application. It is not working, While if we are calling the WebService from a Report, it is working.
    How exactly do we call a WebService from a WebDynPro-ABAP application?
    What are the main steps involved ?

    Hi Phani,
    You will need to create a service call as follows.
    Right click on your WD component name and select Create->Service Call
    The wizard will guide you through a series of steps to make a Web Service Call. On the 3rd screen, it will give you options such as Function Module, Web Service, etc
    Before making a service call, you will need to create a proxy for the Web service in the ABAP Workbench using a WSDL document as a basis. To create or consume Web services, you will need the authorizations associated with the role SAP_BC_WEBSERVICE_ADMIN.

  • Calling webservice from webdynpro thru model(webservice created from BAPI)

  • Problem in calling Webservice from Webdynpro ABAP

    I want to call a BAPI FM which is available in SAP ECC server when user is clicking on a button in a web dynpro application which is available in SAP Portal server.
    For example,
    Portal server name is DVP-EPP &
    ECC server name is DVP-ECC
    I have the done the following steps to achieve it,
    In Server DVP ECC:
    1) Created Web service from the standard BAPI FM (SE37-->Utilities-->More Utilities-->Create WebService --> From the the Func.Module)
    2) Downloaded the WebService as WSDL file from SOAMANAGER
    3) Tested the Web service through SE80, it is correctly calling the BAPI & creating necessary data.
    In Server DVP EPP:
    4) Created a Proxy class as follows,
    a) SE80 --> Package --> Create --> Enterprise service
    b) Selected Object type "Service Consumer"
    c) Selected Service Consumer "Local File"
    d) Browsed and selected WSDL file downloaded from DVP ECC
    e) Selected the Package, Prefix, Request, Completed the process & Activated it.
    5) Configured the Logical port as follows,
    a) Selected my Proxy class through F4
    b) Wrote a name for Logical port, Selected 'Default port' checkbox and selected 'Create'
    c) In the next screen, in 'Call parameters' tab, selected the 'URL' radio button & mentioned the URL of the WSDL-Document created in DVP-ECC system
    d) Saved the data & activated it
    5) Now, tested the service through (SE80-->Package-->Enterprise Services-->Client Proxy) option.
    6) When I test it, system prompts a dialog box for User-Name & Password (as available in DVP-ECC system).
    After the details are given, system throws the Information message as "SOAP:14 Unexpected element -el=definitions ns=http://schemas.xmlsoap.org/wsdl/" - Exception of class CX_AI_SYSTEM_FAULT
    No record is created in DVP-ECC through the WebService BAPI.
    Please tell me whether the steps that I followed are correct as per my requirement and a solution for the above interruption.
    Thanks in advance

    Good day guys,
    Somehow I managed to resolve the above error.
    Now in DVP-EPP system, I am able to Test the Web service Client Proxy (through SE80) and a record is successfully created in destination system (DVP-ECC).
    Now, in Webdynpro I am unable to call this webservice proxy class.
    System throws the error,
    Error (id=SoapFaultCode:5): Web service processing error; more details in the
    web service error log on provider side (UTC timestamp 20141006045544;
    Transaction ID 9A144DE49C12F1B5A6B9E41F137BE3CC)
    I just created a sample WDA application and on click of a button I am calling the Webservice Proxy class as follows,
    Method on_submit_click().
    TRY.
          CREATE OBJECT wd_assist
            EXPORTING
              logical_port_name = 'ZLOG_PORT'. "Logic port creatd for Proxy class (in SOAMANAGER)
          CALL METHOD wd_assist->bus1240create     "Method available in generated Proxy Class
            EXPORTING
              input  = ls_inp                                        
            IMPORTING
              output = ls_outp.
        CATCH cx_ai_system_fault.
      ENDTRY.
    ENDMETHOD.
    Do I have to do any thing additionally in order to call the WebService in WDA?? Because, in the same system, if I test it in SE80, record is perfectly created in destination server.
    Also please suggest if I have to do any other configuration changes related to this.
    Keenly awaiting your reply.
    Have a nice day .
    Thank you.

  • Webservice Exception from Webdynpro

    Hi,
    We are on 7.1 SP04 Patch 1. We have created a webservice with http and None Authentication and deployed on EP 7.0 server. We have set a constant User Name and Password in Visual Admin.
    We are able to execute this webservice successfully from Webservice navigator.
    We have developed a Webdynpro appln with this webservice. We are getting an exception when the webservice is getting executed from Webdynpro appln.
    "Exception on execution of webservice with WSDL url '<wsdl url>' with operation 'webservice name' in interface"
    We checked in the trace file and got the following message
    com.sap.mdm.logging.MdmLogger warning
    WARNING: PingServerCommand failed
    Have any one faced this issue?
    Thanks,
    Arun prabhu

    Hi Walter,
    The webservices are developed using MDM Webservice generator. The webdnpro application has to access MDM Data using MDM Webservices / MDM Java APIs.
    This was working fine with MDM 7.1 SP03. Now we have upgraded to MDM 7.1 SP04.
    When I try to access MDM Data from webdynpro using MDM Java API commands, I am getting an exception at AuthenticateUserSession Command. While access using MDM Webservices, I am getting an webservice exception and an entry in trace file.
    Thanks,

  • Update data in r/3 from webdynpro using bapi

    Hi ,
    i am new to webdynpro.
    i want to update data say sales order in r/3 backend from webdynpro.
    can i have some links for the same.
    i have seen previous forums in following link, but couldn't open.do i need to register to have some extra rights.
    /thread/12846 [original link is broken]
    thanks in advance

    Hi Satya
    In order to update data in R/3 from web dynpro you need to use RFC or BAPI
    The Adaptive Remote Function Call (Adaptive RFC) is a technology that enables the Web Dynpro application developer to use the business functions encapsulated in Business APIs (BAPIs) even after a structure modification, without having to provide the new data using a second back end or a new structure with subsequent regeneration of the proxies.
    Procedure for Importing Adaptive RFC model is as follows
      1. Choose the context menu entry Create Model on the Models node of the relevant Web Dynpro component.
    2. In the model wizard, choose Import Adaptive RFC Model followed by Next.
    3. Make the required entries – for example, to specify where the generated RFC model instances and RFC metadata are to be stored.
    4. In the next wizard window, you enter your user data for the SAP System that contains the BAPIs from which you want to generate the proxies. You use it to log on to the SAP System online.
    To be able to log on to the SAP System, it must be entered in the logon group.
    5.  Next select the BAPIs for which you want to create Java proxies in a generation process. Then choose Next to proceed to the next wizard window.
    6.The import log provides information about the generated model classes, properties, and model relations. Choose Finish to start the generation process.
    Now add this model in "Used Model" for your application
    Now for graphic display you create view,for the progarm control create controller and used this model to retrieve & update data.

    since when i deploy the application into the  SAP portal´s application server, it runs , but  inputfields cannot be written.i dont mean unabled, what i mean, is. cannot write anything on them.ECXEPT the file upload UI element.
    I have reviewed sap help page, 3 sappress books, about dynpro, and the procedure i am performind is agree with them.
    endpoint test answers the folloiwng:
    Message Servlet is in Status OK
    Status information:
    Servlet com.sap.aii.af.mp.soap.web.MessageServlet (Version $Id: //tc/xi/NW04S_20_REL/src/_adapters/_soap/java/com/sap/aii/af/mp/soap/web/MessageServlet.java#1 $) bound to /MessageServlet

    ModuleProcessorClass not instantiated
    ModuleProcessorLocal is Instance of com.sap.aii.af.mp.processor.ModuleProcessorLocalLocalObjectImpl0_0
    ModuleProcessorRemote not instantiated
    what i did is the same as before(in another projects weh i used to import rfc models):
    1.- import webservice model,and add it to component
    2.-map web service model to controller context
    3.-map controller´s context to view context
    4.-create actions and methods
    5.-binding context controller to ui elements
    Dear experts, my questions are:
    What am i doing wrong?
    should i permorm another steps because the web service is in another application server (SAP PI)?
    Should i create a stand alone proxy and then access it from webdynpro?
    when i call the web service model excution it seems does not run, neverthless the invocation does not have any syntax error , what coul it be?
    Thanx in advance!!

    just for the sake of other who may hit this thread , the solution is to add sap-client=<clientno> in the url for wsdl

  • Problem regarding BAPI call from a webdynpro applications

    Hi,
      We are trying to call a BAPI in R/3 system from a webdynpro application through the standard method. But we are getting some problems in JCO settings. We already wasted so much time in solving those problems. Is there anyway where i can access BAPI from Webdynpro application.
    Rgrds,
    Anna

    Hello Anna,
      You can do it by using SAP Java Connector API's in the implementation of the Webdynpro application. You can refer to the sample programs for JCO at http://service.sap.com/connectors and download the latest version of SAP JCo in that install those files as per the installation document in the downloaded zip. The downloaded zip contains information about JCo APIs and sample programs.
    Hope this will solve your problem.
    Best Regards,
    Srinivas.
