Handle hex return values in mapping

Hi

I have a return from SAP Content Server that comes in hex format. My message mapping are not happy and as far as I have understood, normal message mapping and XSLT cannot handle this return.

I have tried with ABAP mapping, but the output stream is still on hex format. Does anyone know how a java mapping can handle this? The input stream is ok, but I would like to output a string (or something else readable for the mapping) instead of the outputstream from the java mapping. Do I have to use StreamTransformation for the java mapping, or do I have any other options?

Thanks!

regards Ole
