I'm testing a web service server in boomi.
I created two profile for request and response. Boomi process will return a message base on response profile. I got 500 error in the test client process. I found in boomi log, there is
com.sun.xml.ws.streaming.XMLStreamReaderException: XML reader error: com.ctc.wstx.exc.WstxParsingException: Undeclared namespace prefix "wss"
wss is not used in my response profile.
I used such an approach for quite a long time and no sissue.
It seems to Boomi introduced an error recently.
