Error in application services, CAF

Hello all,
When testear my application services gives the following error me:
<i>"ERROR. The following exception occured while processing your request: com.sap.caf.rt.exception.CAFFindException.:"</i>
To what it can be due?
Best Regards,
Luis Galey.

Luis,
Check the server log for any exceptions. Make sure your project is built and deployed correctly. Could you post your findBy method and what are the parameters your are passing?
Thanx,
Mahesh

  • Error building Application Service because of  Web Service operator

    Hi  Guys,
    I have a CAF Project and I want to import a standard Web Service from a SAP Java System.
    I can import the Web Service, but I can't generate it. The error is, that two operations, called getProperty and setProperty, are in reserved Namespace.
    Because it is an SAP Web Service I can't change the names of these operations.
    Has anyone an idea how I could resolve this problem?

    Hello Madhav,
    You have to maintain your 'business transaction profile' (SPRO->CRM->IC Web->Business Transaction->Define bus. trans. prof.) in the customizing and assign that profile to your IC WebClient profile (the one you assigned in the org. model)
    In the business transaction profile you must make sure that at least one transaction type (e.g. ZSRV) is assigned as 'Dependent business transaction' and that entry is flagged as 'Service'.
    Also make sure that that transaction type (ZSRV) has leading business transaction category 'Service process' (BUS2000116).
    This should solve your problem!
    Kind regards,
    Joost

  • Error in executing RFC or CAF Application Service

    Hello Everybody,
    I am creating course approval process, in which I am calling RFC for user info and after course approval, calling CAF application service to persist this data.
    But, both services are not working in process. I have tested callable objects for these services and tested successfully.
    But, when I am attaching it in the process then process can't go forward from this point.
    I have checked in Log viewer and found following error:
    Path to object does not exist at com.sap.caf.eu.gp.model.pfw.local, the whole lookup name is sap.com/com.sap.caf.eu.gp.model.pfw.local/GPUWLBridge.
    What should be the problem in this?
    If I remove these services then whole process works fine.
    Thanks in advance,
    Bhavik

    Hello All,
    Is there any concept like, I call perticular backgound object first time then I cannot call that object for some period of time?
    I am getting same error in calling RFC callable object as well as CAF service callable object.
    I can execute these callable objects in the process first time successfully. But, When I execute this process second time, these callable objects won't execute.
    I can execute same process after 3 to 4 hours successfully once.
    What should be the reason behind this?

  • Error while testing an application service

    Hi,
    I have created a project wherein I have imported a standard BAPI as an external service and calling this external service in an application service.
    Following is the code used for the same:
    public com.sap.esproj.appsrv.datatypes.CompanyData getUserDetails(java.lang.String id) throws com.sap.caf.rt.exception.ServiceException {
            // logging

            Object[] CAF_parameters = new Object[] {id};
            com.sap.caf.rt.util.CAFPublicLogger.entering(CAF_user, ESAppServiceBean.JARM_REQUEST, CAF_methodHeader, ESAppServiceBean.location, CAF_parameters);

                   try {
    //                  Call the BAPI.

                        BAPI__USER__GET__DETAIL_dot_Response result = bapi_local.BAPI__USER__GET__DETAIL(params);

                     retValue = new CompanyData();
                     retValue.setFirstName(addr.getFIRSTNAME());
                     retValue.setLastName(addr.getLASTNAME());
                   } catch (Exception e) {

    I have also completed external service configuration.
    There is no compile time error and deployment is successful. When I try to test the application service I am getting the following error: ERROR. The following exception occured while processing your request: com.sap.caf.rt.exception.ServiceException.:
    Can anyone help me in resolving this error.

  • Error while using external service from application service

    Hello All,
    I have exposed webservice from a CAF project that i am importing as external service in another CAF project. Now i am using application service to directly call the external service. following is the code in my application service:
    Ns6_getCountryByCode__R inp = new Ns6_getCountryByCode__R();
                   inp.setNs6_countryCode(countryCode);
                   try {
                          HRServicesWSVi__DocumentLocal bn = this.getHRServicesWSVi__Document();
                          Ns6_getCountryByCode__RResponse result = bn.getCountryByCode__R(inp);
                          retValue.setCountryCode(result.getNs6_Response().getNs3_countryCode());
                          retValue.setCountryName(result.getNs6_Response().getNs3_countryName());
                     }catch(Exception e){
                          throw new ServiceException(e);
    I am getting the following error
    ERROR. Problem in server response: [Bad Request].:
    What could be the problem ? Thanks in advance
    Regards,
    Ashutosh Rastogi

    Hello,
    It's always a good idea to check the log file. In many cases you find hints what the reason for the error could be. The log file can be found here: <root>usrsap<SID>JC30j2eeclusterserver0logdefaultTrace.<xy>.trc where <root> is probably c:, SID something like F33, F41, ... and <xy> a number 0, 1, .... -> the highest number is the last and therefore most youngest log file. Please check out this file.
    Another very common (but trivial) error is that you forgot to specify the URL and the end point location of your Web Service in CAF's config tool. This tutorial explains this beginning on page 20 <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/11669cea-0c01-0010-63b2-b98c35b1b370">Using a Web Service as External Service</a>.

  • Error when trying to create a Composite Application Services project

    Hi Experts,
    I am facing a problem while trying to create a project using NWDS 7.0 SP 13
    New Development Component Project-> Composite  Application Services
    then pressing finish, it throws an error as follows
    "Generation can not completed due to one or more error"
    Reason :
    Errors occurred during code generation
    Warning :
    EAR-META-INF generation failed : null
    Plz help me to solve this
    Thanks in advance,
    John

    Hi John,
    It looks like there might be issue with CAF services related plugins. Check if there are any errors in log file under metadata folder of your workspace.Try deleting the metadata folder & restart the NWDS or start in a new workspace.
    I feel if the issue persists, it is a bug & you can raise an OSS ticket.
    Kind Regards,

  • Errors in Virtual interface after editing application service

    Hi all,
    I have an external service in CAF which connects to the backend to an RFC.
    This external service is being used by an application service.
    I recently added an extra import parameter to the RFC in the backend. So in CAF I deleted my old external service and imported the
    RFC again with the correct import parameters.
    In the Application Service I added an extra import parameter to the input node of the corresponding operations in which the external service is being used. And I inserted a line of code to fill in the correct value in the import parameter.
    After doing this and saving the CAF project a lot of errors are being generated in the ejbmodule of the caf project. (in the Virtual Interface files <servicename>.videf)
    Errors like:
    Type com.spe.portal.foa_serv.appsrv.datatypes.AddressDS of field addressDS0 in type com.spe.portal.foa_serv.appsrv.datatypes.BPartnerLightDS_R has been exchanged by type com.spe.portal.foa_serv.appsrv.datatypes.AddressDS_R
    These errors even occur in the VIs of the services that I didn't change.
    Can somebody tell me what the Virtual interface is for and why they are throwing these errors,
    Thanks
    Kr
    Wouter

    Hi Wouter,
    A virtual interface ia actuallly a xml-file with a description of all the operations and fields of de webservice.
    To solve your problems: go to the navigator view, select the <CAFname>EJB project, navigate to the <servicename> folder under the ejbModule folder.
    Open the wsdef file with the WSD editor and push the button Edit VI....
    Remove the operations under <servicename>Bean and add them again using the buttons below the pane.
    Save and rebuild your work and everything should be ok.
    Hope this helps.
    Regards,
    Alain

  • Unable to instantiate GP process from CAF application service

    Hi,
    I am trying to instantiate a process from my CAF application service as follows.
    IGPProcess process = GPProcessFactory.getDesigntimeManager().getActiveTemplate("7CE44BF090BF11D99817000D60B211F1",user);
    When the execution reaches this step, I am getting the following exception.
    com.sap.engine.frame.core.load.SAPClassNotFoundException
    I suspect that CAF runtime is not able to load GPProcessFactory class. Is there any settings that need to be done or I have to deploy something on the server?
    Please help.

  • Web Service and CAF Application Services - How to return a table

    Hello,
    I'd like to build a CAF Application Service and expose it as a Web Service. This service should return an array or table which I'd like to display in a Visual Composer model.
    I understand that there're limitations at CAF regarding supported data types.
    Does anyone know how to get a workaround?
    Any information is very appreciated.

    You can return a list.
    The standard way to do this is you have to create a complex data type for response.
    Configure the cardinality of this data type to 1..n so as to accomodate a list.
    In your implementation add your list to this response message and return the list.
    This waly you can return collections.
    Hope it helps.

  • Web Dynpro and CAF (BOs, Application Services, returning Complex Types)

    Hi All,
    I am trying to develop an application using Web Dynpro and CAF for days now and did not get it running.. I need some help here.
    What I am trying to do / have done is the following:
    - Design a Business Object (BO) in CAF
    - Implement an Application Service that has a method called getAllBOs that calls the findAll method of the BO
    - call this method using AWS model or EJB model in Web Dnypro, show the result in a table.
    My getAllBOs returns a set of BOs (Data Type is the Complex Type of my BO in CAF). I was able to design the Application Service so that it returns a collection of BOs (using a Wrapper Comple Type), but I was never able to call the generated Web Service successfully in Web Dynpro. The WebService worked fine when testing it in wsnavigator...
    However, i never got it running.. is there anybody out there who is able to explain what to do to import a AWS model or an EJB model in Werb Dynpro and particularily how to implement the stuff so that it returns a set of BOs successfully...
    Thanks in advance.. Useful help is highly appreciated
    Please note: THIS IS ABOUT Netweaver CE 7.1 - do not post stuff about 7.0!

    Hi,
    You have to return a single object from caf layer to webdynpro layer.
    Since you are returning a list of BOs, create a wrapper in caf which contains the list of your BOs.
    Your application service should return this wrapper.
    Creating Wrapper:
    1. Create a complex data type.
    2. Include your BO as one of the properties in it. and set the cardinality to 0..n.
    In Application service invoke your findAll() of BO and use the returned list to populate the wrapper's BO list.
    Return this wrapper.
    Hope it helps.

    Hi,
    I too got an exception like that.
    1. Instead of code
    patentServiceLocal local = this.getpatentService();
    local.update(OBJECT);
    use the following
    this.getpatentService().update(OBJECT);
    I got by problem solved this way.
