BAPI_Flight_GetList throwing error

Hello Everyone,

I am connecting SUP with SAP as backend.


I have created the application in SUP.

I have created the MBO, workflow and have successfully deployed it.

After starting MDS and simulator connection to the server is successful.

However on retrieval of data from SAP i.e. call from BAPI it is throwing java.lang.NoClassDefFoundError.

Could anyone please come up with some suggestions to resolve the same.

I am following the tutorial

Connect, Create, Consume, and Control an SAP Mobile App using SUP

at URL

Thanks & Regards,

    Usually when you get a NoClassDefFoundError the error includes the name of the class it cannot find... can you try to see if you can see more of the error trace?

    Perhaps you have neglected to include the SAP JCo JAR files that are used to connect to the backend at runtime?

    More info on the class that cannot be found will help to diagnose this issue better.

    Hope this helps,
