Consuming a Web Service with ABAP in WAS 6.40 (SS3)

Hi Everyone,
     Has anyone successfully consumed a web service (based on an EJB) that is published to the J2EE engine of their WAS 6.40 server by creating a proxy from the ABAP layer?
     We are encountering the following problem: When executing method of the proxy to call the Web Service on the J2EE engine, the CX_AI_SYSTEM_FAULT exception is triggered with the message "Unallowed RFC-XML Tag (SOAP_EINVALDOC)".
     This same problem has occurred with multiple web services, even though the proxy generation seems to execute without a problem.  Is there some system setting that could cause this?  We have run the SOAP Runtime trace, but only receive the same basic information about the problem.
     If anyone has any thoughts at all, I'd be grateful to hear them.
     Thanks,
        --Greg

Hi,
We encountered problems when consuming a foreign WS. It seems to be that RPC style WSDL isn't supported by the WAS 6.4 WS proxy. An interesting reading on this is

  • Consuming  a Web Service with PasswordDigest Authentication in ABAP

    Hello,
    I need to consume a web service in ABAP from a non-SAP application. The web service uses wsse:UsernameToken with PasswordDigest in the SOAP Header for authentication. However, I havent seen any documentation for using Password Digest in ABAP.
    Is it possible to use Password Digest in ABAP?
    Thanks

  • Consume a Web Service in ABAP

    Hi,
    We have a Web Service URL on PI. Run time of this Web Service in a Portal Server.
    We need to access the Same URL from ECC using ABAP Programming?
    Can any one tell me how we can call the same Web Service?
    I need to pass few values to the web service using ABAP Code and I need to get back the result into some variables.
    any code available for verify?
    Thanks,
    Sekhar.J

    Hi,
    Steps involved in Consuming a Web Service in ABAP.
    1. You will need to create a Service Consumer Proxy in the ECC system.
    The procedure for this is available in the documentation link [http://help.sap.com/saphelp_erp60_sp/helpdata/en/46/9743916d1115ece10000000a114a6b/frameset.htm] in the section Consuming a Web Service.. The URL access path of the WSDL can be used to generate the Service Consumer Proxy in ABAP.
    2. Using transaction SOAMANAGER create the Logical Port for the Consumer Proxy created in Step 1.
    3. Code the Consumer Proxy call in the ABAP program. Check section Consuming a Web Service --> Programming with Client and Server Proxies --> Sending a Message in the link specified above.
    The Video link [Consuming Services in ABAP |https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/media/uuid/20eb3174-41ab-2a10-a383-907faf60eed3] will provide good conceptual knowledge, steps involved and Logical port maintenance..
    In case you face any problems, shoot your queries.

  • How to use web service with ABAP Web Dynpro

    Hi.
         do you know, how to web service with ABAP Web Dynpro?

    Hi,
    If you have a webservice ready with you then you can generate a proxy from SE80 and you can use that. You just have to create a port and assign to that generated proxy(CLASS) and you are good to go.
    Let me know if you need more information.

  • Consuming a Web Service with WEB AS 6.40

    Hello,
    i try to consume a Webservice from the internet. I have configured the logical port and i created the client proxy as shown in the following real good weblog from
    Thomas Jung.
    /people/thomas.jung3/blog/2004/11/17/bsp-a-developers-journal-part-xiv--consuming-webservices-with-abap
    But when i try to test the proxy in SE80 I retrieve the following error:
    <CODECONTEXT>http://www.sap.com/xml_errorcodes</CODECONTEXT>
      <CODE>SOAP:111</CODE>
      <ERRORTEXT>Unallowed RFC-XML Tag (SOAP_EINVALDOC)</ERRORTEXT>
    What's wrong here? Someone can help me?
    Thanks for your help!
    Klaus

    We had the same error message for one of our Proxy Web Service calls.
    We tried to use an RFC instead of the URL, and performed a TEST CONNECTION.  And low and behold, we received an error message that was much more helpful than the "Unallowed RFC-XML Tag (SOAP_EINVALDOC)" message.
    The problem for us was that the Server that we were trying to consume the Web service from was blocking the IP address of our Web Application Server.
    We contacted the administrator, he verified that was the case, removed the restriction, and all is good now.
    Here was the message we saw when we tested it in the RFC:
    The Web server you are attempting to reach has a list of IP addresses that are not allowed to access the Web site, and the IP address of your browsing computer is on this list.  Please try the following: Contact the Web site administrator if you believe you should be able to view this directory or page.
    Hope this helps!

  • Problems consuming a web service in ABAP

    We wish to consume an external web service from ABAP but the provided WSDL file contains syntax not supported by SAP - namely "mixed content".  A response from Roman Glushkov      in forum thread [Call Sharepoint Web Service; seemed to offer a solution. 
    The WSDL file was edited as suggested by Roman and the Service Consumer proxy was successfully created from this edited version.  However, in our SAP release (Basis release 700 support pack SAPKB70018) the "untyped mapping" indicator is not shown anywhere so we are unable to set that for those elements that were set edited in the WSDL.
    The problem now is that when calling a method where the return parameters include one of these edited elements we get the error "SOAP:1,001 CX_ST_MATCH_TYPE:XSLT exception.System expected a value for the type g" presumably because SAP is trying to de-serialise the response rather than just return the data as an XML string.
    Does anyone know how to get this "untyped mapping" indicator or can anyone suggest another way to solve this mixed content issue?
    TIA
    Gareth

    Hi Tim
    I've sort of got further in that I I can now call the web service method without error but structure returned is empty even though I know the SOAP response has data. 
    What I did was to go back to the WSDL and re-write the type declaration bit to fully describe the response message.
    The appropriate portion of the original WSDL was;
          <s:element name="getActionListResponse">
            <s:complexType>
              <s:sequence>
                <s:element minOccurs="0" maxOccurs="1" name="getActionListResult">
                  <s:complexType mixed="true">
                    <s:sequence>
                      <s:any />
                    </s:sequence>
                  </s:complexType>
                </s:element>
              </s:sequence>
            </s:complexType>
          </s:element>
    The response SOAP message was;
    <getActionListResponse xmlns="http://webcominc.com/">
         <getActionListResult>
              <RESULT xmlns="">
                   <RESULT>
                        OK
                   </RESULT>
                   <REASON />
                   <ACTION>
                        View
                   </ACTION>
                   <ACTION>
                        Change Status
                   </ACTION>
              </RESULT>
         </getActionListResult>
    </getActionListResponse>
    So I re-wrote the WSDL as follows;
    <s:element name="getActionListResponse">
       <s:complexType>
          <s:sequence>       
             <s:element minOccurs="0" maxOccurs="1" name="getActionListResult">
                 <s:complexType>
                   <s:sequence>
                      <s:element minOccurs="0" maxOccurs="1" name="RESULT">
                         <s:complexType>
                            <s:sequence>
                               <s:element name="RESULT" type="s:string" minOccurs="1" maxOccurs="1" />
                               <s:element name="REASON" type="s:string" minOccurs="1" maxOccurs="1" />
                               <s:element maxOccurs="unbounded" name="ACTION" type="s:string" minOccurs="0" />
                            </s:sequence>
                         </s:complexType>
                      </s:element>
                   </s:sequence>
                </s:complexType>
             </s:element>
          </s:sequence>
       </s:complexType>
    </s:element>
    Using this new version of the WSDL I recreated the ABAP Proxy but as I said this now returns an ABAP structure that is empty.  I'm new to WSDL so its very probable that my attempt at defining the response message is incorrect or maybe it is something to do with the fact that the response message has two elements called RESULT - one being the child of the other?

  • Consuming Domino web service with JAXB encounters Method Response element

    I am able to consume a Domino R7 (Axis) web service with JAX-WS using Dispatch<SOAPMessage>. When I try using Dispatch<Object> however, JAXB throws an exception because it encounters an unexpected tag.
    The XML from the web service looks like this:
    <Envelope>
        <Body>
            <WebServiceMethodResponse>
                <WebServiceMethodReturn>
                    The meaning of life
                </WebServiceMethodReturn>
            </WebServiceMethodResponse>
        </Body>
    </Envelope>With Dispatch<SOAPMessage>, I can get to the meaning of life quickly using SOAPBody.getElementsByTagName( "WebServiceMethodReturn" ) but with Dispatch<Object>, it appears I must also create a class for the WebServiceMethodResponse element to make JAXB happy. I don't see this happening in other people's examples. Has the Return-element-within-Response-element design been eliminated in pure JAX-WS web services, or is this something that only IBM does?

    In case anyone's search leads them here, I've posted the solution at:
    *[http://www.pby.com/general.nsf/webarticles/dominowebservice01]*
    It is an exhaustive article (not "Hello World"!) that goes through several versions of the web service and client - hopefully explaining all+ pieces of the puzzle:
    ~ web service code,
    ~ WSDLs
    ~ schema
    ~ thoroughly-documented clients that do and do not use JAXB
    ~ ... that use generated artifacts
    ~ ... that customize existing POJOs
    ~ the SOAP messages generated in each direction
    ~ the necessary JAXB annotations
    ~ explanations of how the code works
    ~ explanations of how namespaces affect the code
    ~ on and on and on...
    My constant goal was to write an uncomplicated solution that uses as few artifacts (two) and annotations as possible. The end result is a small, fast JAX-WS 2.0 client that uses JAXB to invoke and consume a secured Domino 7 (1.4.2 JVM + AXIS) web service, using RPC/literal SOAP messages.

  • Consuming SAP web services with tables

    I'm doing kind of feasibility study on consuming SAP web
    services from CF.
    So far so good, but I'm stuck dealing with tables
    (import/export parameters in SAP world).
    I know how to receive a table object from SAP functions:
    * With Apache Axis v1.2: pass an empty CF structure as a
    parameter
    * With Apache Axis v1.4: pass an empty CF array as a
    parameter
    Then the parameter is filled with data (replaced with Java
    object) and we can just parse the object accordingly.
    My question here is whether or not we can pass a *table with
    actual records*.
    For example, I want to pass a table with multiple records to
    update DB records under SAP.
    I tried passing (1) CF array of structure and (2) Java
    ArrayList with no chance.
    The web service call itself completes without errors (no
    method signature error), but the SAP function seems to see the
    parameter as an empty table.
    Anyone has been successful with this case?
    Any suggestion would be much appreciated.

    Thanks Dan,
    Unfortunately CF query object didn't work either.
    Now I'm looking at the code generated by Flex Builder to see
    how the classes are like ;-)
    It's just an ArrayCollection of simple value objects
    (representing a row).
    So CF array of structure or Java ArrayList looks a reasonable
    approach though they don't at all.

  • Exporting to Microsoft Excel from a DataView Web Part consuming a Web Service with Parameters

    In Sharepoint Designer, I've developed a page displaying a DataView Web Part which consumes an XML Web Service with three parameters.  These parameters are passed in from a simple Form Web Part containing three input fields.  I am able to provide default values for the web service so the dataview is initially populated, and when I enter in new parameters, the web service goes back, grabs the requested data and displays in the dataview nice and slick.
    The problem I'm having is this: In Internet Explorer 7, when I right-click on the DataView Web Part and select Export to Microsoft Excel, Excel opens up, says "ExternalData_1: Getting Data..." and returns the data from the web service which applies to the default parameter values each and every time, regardless of whether I have changed the parameters on the web page, and contrary to what the DataView Web Part displays on the screen.
    Has anyone else run into this, and is there a solution to the problem?
    Best regards,

I'm guessing I need to somehow include jax-ws objects in my deployment, but how do I do this? - I'm a little out of my depth here, so please explain thoroughly
    Thanks

    Hi,
    We encountered problems when consuming a foreign WS. It seems to be that RPC style WSDL isn't supported by the WAS 6.4 WS proxy. An interesting reading on this is

  • Consuming Java Web Service with complex return types

    Hi,
    I'm consuming a Java Web Service and the return I get in
    ColdFusion is a typed Java Object (with custom Java classes like
    com.company.project.JavaClass ...)
    Within this object I don't get direct accessible properties
    as when I'm consuming ColdFusion Web Services, instead I get a
    getPROPERTYNAME and setPROPERTYNAME method for each property.
    How can I handle this? I don't want to call this methods for
    each property (and there are nested objects with arrays of custom
    classes below, which would really make this complicated).
    What's the best way to cope up with this?
    Thanks a lot,
    Fritz

    The web service is actually the function, not the cfc and you
    didn't show a function.
    My own opinion is that since webservices by definition should
    be available to any calling app (cold fusion, .net, flash, etc),
    whatever gets returned from the method should be as universally
    recognizable as possible. This generally means text, numbers,
    boolean, or xml.

  • Consuming a web service with header

    Hi
    I am trying to consume a web service in BIP.
    But the problem is that the authentication is in the header of the SOAP, it does not take the values provided in username/password field in complex type service.
    (However i am able to see the methods in the body of the web service.)
    hence i get an error "username not specified"
    how do i pass the credentials in the header of the soap?
    I am using BIP 10.1.3.4

    This is the output at the oc4j when I try to execute:
    After WSS soapMessage = <soap:Envelope xmlns:soap="http://sche
    mas.xmlsoap.org/soap/envelope/">
    *<soap:Header></soap:Header>*
    <soap:Body xmlns:ns1="urn:XYZ_Request">
    <ns1:OpGet>
    <ns1:Request_ID>000000000000019</ns1:Request_ID>
    </ns1:OpGet>
    </soap:Body>
    </soap:Envelope>
    Notice that Header is null. I want to pass the authentication in the header.

  • JAVA Stack for consuming and providing Services with ABAP?

    Hi Experts,
    I would like to know if I need to have a Java Stack when I want to build a Web Application with Web Dynpro Abap and consume Enterprise Services from the Enterprise Service Repository. Additional own created services in ABAP should be provided. Is a Java stack necessary for that? Or is an ABAP Stack enough?
    Thanks a lot for your answers?
    Best regards,
    Ingmar

    Hi Ingmar,
    You do not need a Java stack to build or run Web Dynpro ABAP application. Web Dynpro ABAP runs on ABAP stack.
    Just to consume a web or enterprise service from Web Dynpro ABAP application, or any ABAP application for that matter, you do not need Java stack, either. NetWeaver Application Server contains a component called ICM (Internet Communication Manager) that enables the AS to play both as a service provider as well as a consumer.
    The part about consuming Enterprise Services from the ES Repository is more complicated, though.
    ES Repository is only a modeling tool. Services are actually implemented  in the respective backend systems and then registered in central Services Registry. So, if the Enterprise Service you want to consume comes from an application that runs on Java stack, although I do not have any example of that handy, then obviously - Java stack is needed. This is irrelevant, however, if your question only pertains to the consumer part.
    I hope this helps.
