I am consuming the wsdl file for web service given by the external client i have tested in SoapUI which was working fine when i tried to do test in designer it was giving the below exception message.
Unexpected EOF in prolog
at [row,col {unknown-source}]: [1,0]
please check with an editor which can display special characters if there is additional content in front of “<?xml version="1.0"?>”.
Sometimes you will find the so called ByteOrderMark here which might be confusing the WSD-Creation Dialog.
