Please help: WSDLException for missing namespace attribute

[Juzer Kothambawala <jk...@cisco.com>]

Hi,

I am trying to build a web services that takes in a document and returns a 
zip file as soap attachment. Generating Java stubs and skeletons works fine 
using the wsdltojava tool. However after deploying the service when I try 
to generate the wsdl (using 
http://localhost:8080/axis/services/Pip2A1Bootstrap?wsdl), it throws the 
following exception:


Fault - WSDLException: faultCode=PARSER_ERROR: Problem parsing '- WSDL 
Document -'.: The value of the attribute 
"prefix="xmlns",localpart="tns2",rawname="xmlns:tns2"" is invalid. Prefixed 
namespace bindings may not be empty.: org.xml.sax.SAXParseException: The 
value of the attribute

Also when I look at the client request, it is missing the default namespace 
in the input document inside the soap body. It looks as follows:

POST /axis/services/Pip2A1Bootstrap HTTP/1.0

Content-Type: text/xml; charset=utf-8

Accept: application/soap+xml, application/dime, multipart/related, text/*

User-Agent: Axis/1.1beta

Host: localhost

Cache-Control: no-cache

Pragma: no-cache

SOAPAction: ""

Content-Length: 427

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <soapenv:Body>
   <DataRequest xmlns="">
    <ParamList>
     <Parameter>
      <Name>PriceListId</Name>
      <Value>GLU</Value>
     </Parameter>
    </ParamList>
   </DataRequest>
  </soapenv:Body>
</soapenv:Envelope>


The WSDL file is as follows:

I have spent lot of cycles trying to figure out the problem including 
searching the mailing list. I would greatly appreciate if you can examine 
the wsdl and point out the problem.

Thanks.
