  2. What are your namespace prefixes?[ Go to top ]

    Well, "invalid QName prefix" suggests that there could be an issue with the characters in a namespace prefix that you are using. Can you list the namespace prefixes that your instances and Schemas are using? Cheers, Tony.

  3. wsdl[ Go to top ]

    the wsdl it generates there all all the prefixes <?xml version="1.0" encoding="UTF-8" ?> - - - - - - - - - - - - - - - - - - -

  4. What about the instances?[ Go to top ]

    I don't see any obvious prefix issues in the WSDL, but the exception occurs during an invocation, which I guess means it happens as a message arrives. That means the prefixes in the arriving instance could also be the problem. Are you able to see the instance/message that triggered this exception when it occurs? Do you log it anywhere, for example?
