Call a service with an document output in an portlet

Hello all

I currently try to create a portlet which calls an IS service. The output of this service is a IS Document (i simplify it in way that this document contain only a few strings). In the Designer I can successfully create this with a table as output (as provided by the drag and drop assistant).
When i deploy this to MWS (all 7.1) i get different error messages. The same scenario with a standard string output work fine.

Thanks for all your hints

Regards
Josef

Hello

I normally get a:

Invalid byte 2 of 3-byte UTF-8 sequence.

error message. Which means to my knowledge a not UTF-8 conform content. But i dont use any special character in this, only lower case string and numbers.
As follow up error message i normally get

java.rmi.UnmarshalException: java.io.IOException: no argument constructor is missing.

Hello all

I solved the problem by modifying the Output of the service (the Document). In this Document was a Document list which contains an “ä” in the naming. Under normal circumstances UTF-8 supports such character.
Anyway after doing this it works.
