I’m running on IS 8.2.2 and have a provider web service with attachments enabled set to true on the WSDL I generated and I’ve set MTOM to true within SOAPUI. In the flow service that receives this attachment, I am calling pub.soap.utils:getXOPObjectContent to retrieve the content as Stream and this is working and I’m even able to write out the image/tiff to our file system. However I am getting these annoying log statements on the server.log every time this is called:

XMLCoder decode invalid data type: com.wm.util.XOPObject
XMLCoder decode invalid data type: java.io.FileInputStream

Both of the above come out of the same call. Is there any way to get rid of or fix this error that is logging? Am I missing something?

Thanks, Diane

you can reduce the logging, on IS admin UI:
Settings > Logging >Server Log
change 0076 Coders to: Error or Fatal (or even off)
default is Info.
