Consuming webservice in a webdynpro component

Hi Experts,
I have a third party free webservice as WSDL link.My requirement is to make use of that webservice in my webdynpro component.
Can any body give me a step by step approach to consume that webservice in my webdynpro Component.
If possible, Provide me some good material for consuming webservice in a webdynpro component.
Awaiting for a useful reply.
Thanks,
Ramanan.p

It is possible to create webservice in ABAP as well as in Webdynpro.

In Web Dynpro ABAP there is nothing special about calling a web service. Unlike WD Java, there are not dedicated model object types in WD ABAP. WD ABAP simply has the ability to interact with other ABAP development object types. You can call function modules, ABAP classes, even modules in old dynpro apps.
So calling the webservice from ABAP therefore is just the process of generating the ABAP Proxy Class. This is the same process regardless of if you want to use this proxy class from WDA or any other type of ABAP development object. You can then call the proxy class from WDA just like any other type of ABAP class. There is a service wizard option in later support package levels that includes an option for ABAP Proxy classes - although it doesn't generate the proxy class it just generates the code and context for the call to an already existing proxy class. The service wizards in WD ABAP are not required however. They are just shortcut code generators and often can't even generate a complete context for a complex web service proxy - so expect to do some manual adjustment after running the wizard.

  • Consuming WebServices in ABAP WebDynPro via webservice proxy code

    Hi,
    My requirement is to consume a webservice using WSDL(basic authentication) in WebDynPro ABAP. then based on the SOAP response I need to show a pop up message whether the response valid or not.?
    I first tested the webservice by creating LPCONFIG Logical Port and generated WebService Proxy class.
    It got response correctly with basic authentication enabled each time I send a request.
    Secondly I generated webservice proxy code using service calls on creating webdynpro test application with some UI elements. Service call created Nodes,attributes and method correctly.
    it's giving me error when it tries to invoke webservice method through generated code.
    Question is that How do we code authentication to the webservice method via WebDynPro ABAP code.
    I appreciate anyone who worked on this area and taken basic authentication via coding. or worked successfully through coding.
    Thanks

  • XI Webservice Exception within Webdynpro component

    Hi All,
    I have created a model for an XI webservice within the webdynpro project and created 2 view one for search and the other for search results and have accordingly associated the context variables of these views to the import and response parameters of the web service.
    Now when I execute the method associated with this service I receive a service exception as enclosed below :
    Service call exception; nested exception is: com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeException: Invalid Response Code: (401) Unauthorized
    Can someone please tell me if there any settings to be done on the client or server settings.

  • Consuming Webservices in webdynpro ABAP

    Hello,
    I want to work with consuming Webservices in Webdynpro ABAP. Can anybody give an example for the same.
    Any help would be highly appreciated.
    Thanks.

    Hello
    Here is a link.
    It has many links for the webservice consumption in abap and web dynpro
    Consuming webservice in a webdynpro component
    actaully process on a high level is like this.
    1. first you need to create an client proxy., For creating this go to SE80
    and follow this link
    http://help.sap.com/saphelp_nw04/helpdata/en/bf/d005244e9d1d4d92b2fe7935556b4c/content.htm
    2. then you can consume this service using the service call option of the web dynpro
    here go to the web dynpro comp and right click on it and create-> service call
    and use  the proxy created in the first step here.
    it will create one custom controller which you can use.
    thanks

  • Consuming MII WebService in Java WebDynpro

    Hello,
    We are facing a strange situation...
    We define a transaction in MII to be consumed as WebService in Java WebDynpro. This transaction is a simple query on a DB returning 4 fields :
    Shift code : SHIFT
    Shift description : DESCRIPTION
    Start time : START_TIME
    End time : END_TIME
    It works fine, we use the import adaptative web service wizzard in netweaver developper studio to use this WS...
    But if we to an update on the webservice, changing a field name for example (SHIFT -> SHIFTCODE), we start to have trouble...
    We got then the very helpful error message :
    Exception on execution of web service with WSDL URL '<sever>/WebServices/GetShift' with operation 'Xacute' in interface 'XacuteWSSoap'
    If I display the model info using wdContext.currentRequest_XacuteElement().modelObject().associatedModelClassInfo().getModelInfo().toString()
    I got the following (extract) :
    <ModelClassPropertyInfo name="SHIFT" dataType="com.sap.tc.webdynpro.model.webservice.types.string(java.lang.String)" readOnly="false" qName="SHIFT" required="true" backendType="null"/>
    As you can see, the model definition is NOT updated and we still have SHIFT as name instead of SHIFTCODE...
    If someboby has an idea, it will save us our life ;o)
    Thank you
    PS:it the same behaviour if we add a field...

    Oliver -
    Did you try to reimport the WS model ..? If yes and still doesn't work...Try  to delete the old proxy in webdynpro ( adoptive ws) and import again.
    To avoid code changes,you can give same old name while fresh import.
    Adoptive WS in webdynpro  is not really like Adoptive RFC .It has some limitations.
    Thanks

  • How to consume a ABAP webservice in a  webdynpro app?

    Hi,
    I have a BAPI in ABAP that is exposed as a webservice. I want to use this to build a webdynpro app so that i can consume this webservice. This BAPI returns the Employee data. As soon as the person logs into the portal i am going to pass his login id to this BAPI so that it retrieves the Employee data for that user id. But i need to know the procedure of consuming this webservice in a webdynpro app. Any pointers in this regard will be greatly appreciated.
    Thanks,

    Hi Arun,
    Consumption of a web service is univesal I guess so it wont matter if it is an ABAP webservice. For consumtion of webservice in Web Dynpro you can go through the following tutorials

  • Consuming Webservice in WebDynpro - Content-Type issue

    Hi,
    I am getting a shortdump when consuming WebService in WebDynpro.
    I trace it back to the class CL_SOAP_HTTP_TPBND_ROOT method GET_HTTP_HEADERS whereby the
    value = 'text/html; charset=iso-8859-1' while the constants tsrc_soap_11_http_content_type = 'text/xml' ; tsrc_soap_bx_http_content_type = 'application/x-sap-bxml' ; tsrc_soap_mtom_http_cont_type = 'application/xop+xml' ; tsrc_soap_mp_http_content_type = 'Multipart/Related'. Because of this Content-Type difference my WebDynpro application dumps?

  • Invalid WSDL while consuming webservice

    Hi ,
    I have done with soap to proxy interface  in PI7.1 EHP1,
    Now i am trying to publish the sender agrement to service registry i am facing the issue as
    Service Registry configuration issue
    because of this i have created wsdl file from display wsdl tool  in directory using the
    http://<host>:<J2EEport>/XISOAPAdapter/MessageServlet? channel=<party>:<service>:<channel>
    and now  i tryed tested this wsdl file by using soapui its working fine.
    the same wsdl when i am using in creating a webdynpro applicaiton to consume this wsdl file i am getting as invalid wsdl file.
    i have followed the link to create a consume webservice
    http://www.riyaz.net/blog/xipi-consuming-xi-web-services-using-web-dynpro-part-ii/
    Kindly suggest me is there any new way to create wsdl in 7.11 as i see old version 7.0 wsdl are wroking fine while creating a model in webdynpro application.
    Regards

    Edited by: vijay Kumar on Jun 9, 2010 1:31 PM

    Hi,
    Since you are using PI 7.1, you need not to define the websierce by using wizard in the integration directroy.
    In PI 7.1 it is not required to manually formulate your sender SOAP URL, generated WSDL contains all the required information.
    Directly Go to Integration Directory - - - -> Sender Agreement - - - > Display WSDL
    This would help you:

    To enhance the layout of the view, you can create new UI elements. This procedure is no different u2013 from a technical viewpoint u2013 from creating UI elements in components themselves. All UI elements created within the enhancement implementation can then be processed as usual.
    Enhancements  means inserting user developments into SAP development objects at predefined positions.
    The Enhancement Framework enables you to add functionality to standard SAP software without actually changing the original repository objects, and to organize these enhancements as effectively as possible.

  • How to call a RFC of a remote system from an ABAP webdynpro component

    Dear Experts,
    I am a newbie in ABAP Webdynpro.
    I am working on a requirement where I have a webdynpro component on ECC system.I need to call a RFC located on CRM system from my webdynpro component on the ECC system.
    How do I do that ?? Please help.
    Regards,
    Mamai.

    Calling RFC from some other system is same as local except the difference is that you have to give destination name while calling.
    And the regarding the method of calling it depends on your FM.
    if it is big RFC with complex structure, you can create the service call for it with destination given as RFC desitination.
    if it is simple straight forward RFC you can directly call it.
    for creating RFC service call call use this method
    1. Starting the Wizard
    To start the wizard, position the cursor on the Web Dynpro component to be edited in the object list at the left margin of the
    workbench window. Open its context menu and choose the entry Create->Service Call. The wizard is started and leads you
    through the creation process.
    Press Continue.
    2. Choice of Controller
    On the second dialog window of the wizard, you can choose whether the service call is to be embedded in an existing
    controller or whether a new controller is to be created for this purpose. Service calls can only always be embedded in
    global controllers u2013 that is, in the component controller or in additionally created custom controllers. It is not possible, to
    embed service calls in view controllers.
    a. Select radio button Use Existent Controller
    b. Do not change the default entry for component: <CC name>
    c. Enter for controller COMPONENTCONTROLLER
    d. Press Continue.
    3. Service Type and Service Selection
    a. You now select, which service type should be used for this service call. Select radio button Function Module. Fill the
    destination here. Press Continue.
    b. Select the service: for Function Module enter <RFC name>. Press Continue.
    4. The Required Methods and Context Elements
    On the two subsequent dialog windows, default values are listed for giving names to the context nodes and attributes
    required by the service call as well as to the required methods. The proposed names are based on the names of the
    embedded service, but you can change them as required. However, heed the respective notes in the corresponding dialog
    box.
    a. Adapt Context: Select from Nodes/Attributes . Press Continue.
    b. Specify Method Name: leave all entries as provided: Component:  Controller: COMPONENTCONTROLLER Method: EXCUTE_ Press Continue.
    5. Completing the Choice
    When you have confirmed the last dialog box, the generation is triggered. Afterwards you now have the required methods
    and contexts at your disposal for using them within your Web Dynpro component.
    or if you want to call directly the use the call statement with destination
