Please help: WSDLException for missing namespace attribute

[Juzer Kothambawala]

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 "prefix="xmlns",localpart="tns2",rawname="xmlns:tns2"" is invalid.

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:

<?xml version="1.0" encoding="UTF-8"?>

</wsdl:port>

</wsdl:service>

</wsdl:definitions>

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.
