Error - Creating a Web Dynpro Application Accessing ABAP Functions

[Former Member]

Dear All,

we are trying to implement a web dynpro application with accessing ABAP functions.

Previous tasks:

- insert the ABAP system into the SLD from the NWDI System (Transaction RZ70; the ABAP system is correctly insert into the SLD => technical systems)

- equipped the JCO connections with the web dynpro content manager (ping and test = OK)

It’s the standard tutorial out of the SDN called “Creating a Web Dynpro Application Accessing ABAP Functions”.

Some hints:

- There are no errors after the implementation and the “rebuild” of the project in the NWDS

- The auto deployment works fine to the development runtime system. The application is shown in the Web Dynpro content manager

- The In the build log I found these entries:

- I’m able to start the application out of the Web Dynpro content manager with “run” => only the user interface is displayed without any functionality

- The “normal” start over the NWDS fails => error text

“com.sap.tc.webdynpro.services.sal.core.DispatcherException: The requested deployable object 'local/J08_Flugdat_D_aventdcflight~xxx.com' and application 'FlightListApp' are not deployed on the server. Please check the used URL for typos.”

There two different URLs in use.

Start via NWDS:

http://frasapp562:50000/webdynpro/dispatcher/J08_Flugdat_D_aventdcflight~xxx.com/FlightListApp

Start via web dynpro content manager:

http://frasapp562:50000/webdynpro/dispatcher/xxx.com/aventdc~flight/FlightListApp

For test purposes, we started the BAPI (BAPI_Flight_Getlist) on the ABAP system directly. It works.

Any ideas about the system behaviours (different URLs and missing functionality)?

Thanks a lot in advanced!

Best regards

The Error has been solved – The implementation of a method was missing....

Thx
