Apr 19, 2004 at 02:58 PM | 6 Views

Hi ...

I am facing a serious problem while trying to run the Web Dynpro application.

The JCO connections are tested fine while trying from WAS server, but giving the following error when tried to run ...

com.sap.tc.webdynpro.services.exceptions.WDTypeNotFoundException: type extern:com.sap.model.examples.types.IFlightsModel:com.sap.model.examples.types.Bapisfldst could not be loaded: com.sap.dictionary.runtime.DdException: failed to create provider: null

Please help.

    Hi there

    I ran it to the same problem, but when I changed the way the models are bound to the nodes , it worked . Are you testing this on some standard Function modules . I could check this up for you

    Regards

    Pran

      Hi Pran,

      Thanks a lot for the reply. I am not using the nodes. I am using the simple application where I have a view set and 2 views. when I press a button, the results shud be displayed.

      I am using the BAPI GET_FLIGHT_LIST.

      It gives the error

      "com.sap.tc.webdynpro.services.exceptions.WDTypeNotFoundException: type extern:com.sap.model.examples.types.IFlightsModel:com.sap.model.examples.types.Bapisfldst could not be loaded: com.sap.dictionary.runtime.DdException: failed to create provider: null

      Please help.

    Hi,

    it seems that your JCO-Destinations are not defined in a proper way..

    It is important, that you use two JCO-Destinations;

    one for the Dictionary Data and the other one for the Application-Data.

    You have to define two differnt Destinations, one of Type 'Dictionary Meta Data' and one of Type 'Application Meta Data'. Both point to the same R3 System!

    The first one could access the R3 System only via MessageServer, so you have to take care, that accessing the R3-System via MessageServer must work properly.

    Hope this helps, Frank.
