Could not create JCOClientConnection

[Former Member]

Hi,

I have follow closely to the tutorial 'How to... execute an RFC model with inputs from Interactive Forms', but a problem encounter during the testing.

Error :

Could not create JCOClientConnection for logical System: WD_MODELDATA_DEST - Model: class com.sap.demo.flightchecking.model.FlightCheckingModel. Please assure that you have configured the RFC connections and/or logical system name properly for this model!

What causes this? Anyone have any solution for this error?

Thank you in advance.

Best Regards,

Hello,

The answer is in the error:

<i>Please assure that you have configured the RFC connections and/or logical system name properly for this model!</i>

Register your backend system in the SLD, then create corresponding JCo destinations in the web dynpro administration interface accordingly. By default you have one for the Metadata and one for application data.

Hi Francois,

Thanks for your valuable feedback. I'm quite puzzle why there is JCO connection involve as the tutorial never mention anything on JCO connection. Pardon me, I'm new to interactive form.
