My service replies correctly when the correct input is given, but when a bad SOAP message is sent, such as a typo in an opening tag but not a closing, the client gets no reply and the server logs an exception a la:

15:21:29,103 ERROR [STDERR] [Fatal Error] :4:60: The end-tag for element type "CustomerID" must end with a '>' delimiter.
15:21:29,104 ERROR [SOAPFaultExceptionHelper] SOAP request exception
java.io.IOException: org.xml.sax.SAXParseException: The end-tag for element type "CustomerID" must end with a '>' delimiter.
