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........................
  CALL FUNCTION 'CONVERSION_EXIT_ALPHA_OUTPUT'
       EXPORTING
            INPUT  = ORDER
       IMPORTING
            OUTPUT = ORDER.
*........Convert Item Number to External Format.........................
  CALL FUNCTION 'CONVERSION_EXIT_ALPHA_OUTPUT'
       EXPORTING
            INPUT  = ITEM
       IMPORTING
            OUTPUT = ITEM.
*........Convert Material Number to External Format.....................
  CALL FUNCTION 'CONVERSION_EXIT_ALPHA_OUTPUT'
       EXPORTING
            INPUT  = MATERIAL
       IMPORTING
            OUTPUT = MATERIAL.
  CONCATENATE 'sOrder=' ORDER
               INTO REQUEST_BODY-DATA.
  APPEND REQUEST_BODY.
  CLEAR REQUEST_BODY.
  CONCATENATE '&sItem=' ITEM
               INTO REQUEST_BODY-DATA.
  APPEND REQUEST_BODY.
  CLEAR REQUEST_BODY.
  CONCATENATE '&sMaterial=' MATERIAL
              INTO REQUEST_BODY-DATA.
  APPEND REQUEST_BODY.
  CLEAR REQUEST_BODY.
  CALL FUNCTION 'HTTP_POST'
       EXPORTING
            ABSOLUTE_URI          = MYURL
            RFC_DESTINATION       = DEST
            BLANKSTOCRLF          = 'X'
       TABLES
            RESPONSE_ENTITY_BODY  = RESPONSE_BODY
            REQUEST_ENTITY_BODY   = REQUEST_BODY
            RESPONSE_HEADERS      = RESPONSE_HEADERS
            REQUEST_HEADERS       = REQUEST_HEADERS
       EXCEPTIONS
            CONNECT_FAILED        = 1
            TIMEOUT               = 2
            INTERNAL_ERROR        = 3
            TCPIP_ERROR           = 4
            DATA_ERROR            = 5
            SYSTEM_FAILURE        = 6
            COMMUNICATION_FAILURE = 7
            OTHERS                = 8.
  CHECK SY-SUBRC = 0.  "more appropriate msg goes here
  LOOP AT RESPONSE_BODY.
    IF RESPONSE_BODY+0(7) <> '<string' AND
       RESPONSE_BODY+0(8) <> '</string' AND
       RESPONSE_BODY+0(5) <> '<?xml'.
      SPLIT RESPONSE_BODY-DATA AT '=' INTO FIELD_NAME FIELD_VALUE.
      TRANSLATE FIELD_NAME TO UPPER CASE.
      CASE FIELD_NAME.
        WHEN 'HEIGHT'.
          HEIGHT = FIELD_VALUE.
        WHEN 'WIDTH'.
          WIDTH = FIELD_VALUE.
        WHEN 'LENGTH'.
          LENGTH = FIELD_VALUE.
        WHEN 'WEIGHT'.
          WEIGHT = FIELD_VALUE.
        WHEN 'QTY'.
          QTY = FIELD_VALUE.
      ENDCASE.
    ENDIF.
  ENDLOOP.
Hope this helps...

    Thanks in Advance.

    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.

  • Calling web-service from non-SAP client

    Hi,
    Could anyone here help me with the code with which we can call the non-SAP service in java from a java client.
    I have the wsdl and service deployed on the server.
    Regards,
    Manoj

    Hi Eduardo,
    We are trying to consume a non-SAP webservice (https based) which uses a certificate issued by the non-SAP web service provider for authentication.
    We tried consuming the web service using the Web Dynpro Java's Adaptive WebService Model method. We configured the Logical Destinations with X.509 client certificate authentication and have added the certificate to the WebServicesSecurity keystore.
    However, when we run the application, we get the 'Peer certificate rejected by ChainVerifier' error.
    Could you guide us on how to resolve the same ? If possible would you also provide the step-by-step details of how to create the EJB application that you did to achine this ?
    Any help is greatly appreciated.
    Thanks.

  • Is there a way to call web service from 2 servers??

    Hi,
    I need to know if its possible to call web service from 2 different servers without having load balancer??? I mean, if one of the server has heavy work on, then it should call web service from the other server.
    Thanks in advance.
    Best Regards.

    Hi,
    WebLogic Cluster has this feature ( Load Balancing & Failover ). If you will deploy your WebService to a WebLogic Cluster and then If you will put a Proxy in front of it like (Apache)...Then it is Possible.
    <h3><font color=maroon>What All You Need To Do ? ...... as following</font></h3>
    <b><font color=maroon>Step1).</font></b> Create a WebLogic Cluster (minimum two ManagedServers)
    http://weblogic-wonders.com/weblogic/2010/04/28/weblogic-clustering-in-remote-boxes/
    <b><font color=maroon>Step2).</font></b> Install a Proxy like Apache in frot of them like following:

    http://weblogic-wonders.com/weblogic/2010/08/01/weblogic-httpclusterservlet-proxyserver/
    <b><font color=maroon>Step3).</font></b> Now Configure a FrontEnd Host for your Cluster by providing the ProxyServer Host name as the FrontEnd of your Cluster. This step is required to Generate the Dynamic WSDL with the Address of the Frontend.(Not of a perticular WebLogic Server)
    http://weblogic-wonders.com/weblogic/2010/06/21/configuring-frontend-host-and-port/

  • Calling Web Service from CRM using proxy

    Hi all,
    I'm facing a problem trying to call a web service from CRM (WAS 620) via XI 3.0. The response that XI recieves from the web service contains SOAP Envelope, and the mapping fails because of it. I built the proxy manually, because if I load WSDL the proxy generation in CRM generates error that sais that external definition coudn't be used.
    Is there any way to remove SOAP envelope from the response while mapping?
    Is it possible to call web service from WAS 620?
    Thanks!!!!
    Anya.

    Hi Manish,
    SOAP adapter does pass the message to XI (this message contains SOAP envelope although XI expects to get message without it), and during the mapping step i get "Runtime Exception in Message-Mapping transformatio~".
    I suppose it's because i created proxy manually. I did so because when i imported WSDL, and tried to generate proxy in CRM, i got an error message that said that proxy couldn't be generated because external definitions are only allowed in XI 3. But my XI version is 3.0! And when I generate the same proxy in my R/3 system that is installed on WAS 640, it works.
    What can I do?
    Cheers,
    Anya.

  • How do i call web services from SAP ABAP

    Hello,
    Ian working with .net team. they are using sap .net Connector to connect SAP.

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.

  • 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..
