Error in tutotial "How to ... Build a Web Dynpro Application"

[Former Member]

Hi,

I deployed this tutorial in my WAS 6.40 and had the configuration in the SLD and in the Jco connection.

When I tried to execute it I received the messages below:

Error stacktrace:

Important: I execute the tutorial "FlightBooking" and it is working well, and I'm using the same Jco specifications.

Hi Flavio,

It looks like your back end box does not have the type FlightListModel in it. This can happen for any of a couple of reasons, the Metadata JCO connection could be wrong (but you indicate it is just fine), the back end function module and associated types may not exist on your back end system, or the metadata cache on the J2EE engine is filled with the wrong data (or is simply missing data). If the first two are double checked and there is no problem, you might try restarting your J2EE engine which would re-load the metadata cache.

Hope this helps,
