Hi Umberto,

Did you verify if the name and the namespace is correct in the integration directory (please use always the value help and do not type in the names manually)? Did you reference the correct Message Mapping in your Interface Mapping? Did you activate your Interface Mapping?

Best regards

Umberto, i have at times faced this classnotfound exception at runtime. This used to happen in our qa box, when we are having messages in the integration engine, at the same time, we are trying to transport object from dev to qa. When we do an import, a cache refresh happens, and i think there is some kind of lock that happens when a class file is refreshed. Thsi may lead to this error. We used to do a restart of this message and it will go through. If this is the case , you can restart the message.

I don't understand, as i can restart the message??

Hi,

I am not sure if this is will help, but to restart a message, just go to SXMB_MONI, and seelct your message and then from there , you can click on the button RESTART, to restart your message.

I have tried more times to regenerate the message but it always goes in error.

Umberto, Do you see this mapping program in SXI_CACHE ? At runtime, mapping runtime will look at this cache. If for some reason , it is not reflected(!!) there, may be u can try reactivating the mapping in IR. Not sure thoe, Is it happening for all ur mapping programs or for this one alone ?

The error says:

<i>Class not found: com.sap.xi.tf._Z_MM2SUSSupplierPortalTradingPartner_</i>

are you using graphical message mapping?

If you are using Java mapping then its all about your imported archive. Verify the same.
