[Java-Mapping] Error with wrong input

Hey,

I created my first Java mapping and included it in a working SOAP->XI->RFC

scenario. Now I have an strange behaviour, because if I fill the web service

with correct information everything works fine. Did I insert wrong information

he returns following error:

<i>

com.sap.aii.af.mp.module.ModuleException: com.sap.aii.af.ra.ms.api.DeliveryException: XIServer:NO_MAPPINGPROGRAM_FOUND: caused by: com.sap.aii.af.ra.ms.api.DeliveryException: XIServer:NO_MAPPINGPROGRAM_FOUND:

</i>

What happend here? Is it because he couldn't handle a rfc error? The response of

the rfc is still handled with a standard message mapping.

thanks

chris
