Re: Empty namespace - again

Fri, 11 Mar 2005 12:53:34 -0800

The schema spec leaves no room for doubt on this issue. Here's an excerpt of the schema element definition:

<schema
attributeFormDefault = (qualified | unqualified) : unqualified
blockDefault = (#all | List of (extension | restriction | substitution)) : ''
elementFormDefault = (qualified | unqualified) : unqualified
finalDefault = (#all | List of (extension | restriction)) : ''
...

The elementFormDefault attribute defaults to "unqualified" if not supplied, meaning that only the global elements and types are namespace qualified.

Yes !  Ack!

I have seen this before.

When the schema does not declare an elementFormDefault , .NET assumes it is one way, And AXIS assumes it is the other.

This is a bug in one or the other.(I don't know what a schema parser is
expected to do with EFD is missing). 

The workaround is to specify elementFormDefault, one way or the other,
in the schema.

Good catch, Anne!

Anne,

Please award yourself a gold star! The elementFormDefault="qualified"
solved it, and 18:24 on a Friday night in an empty office after a [very]
long week.  ;-}

I've copied this to Dino for his interest.

Many thanks again,

        Richard.

I'm surprised that .NET got confused by this, because normally it handles valid schema definitions. Perhaps Dino can shead some light on





it. But here's a work around. Add the elementFormDefault="qualified"
attribute to the scehma definition, which will make the <return> element namespace qualified.

Anne,

I did, but it didn't!

Here is my bit of C# built in Visual C#.net pulling in the Web reference of my wsdl as supplied by my Axis server:

static void Main(string[] args)
{
ConsoleApplication1.rjwpc.LookupBorrowerService srv = new ConsoleApplication1.rjwpc.LookupBorrowerService();
String ret = srv.echoString("Hi there");
Console.WriteLine("Response: "+ret); }

It ret is set to null after the echoString() call. Digging


in to the


auto created C# code I get the following:

/// <remarks/>
[System.Web.Services.Protocols.SoapDocumentMethodAttribute("",
RequestNamespace="urn:LookupBorrower",
ResponseNamespace="urn:LookupBorrower",
Use=System.Web.Services.Description.SoapBindingUse.Literal,



ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrappe


d)
]
[return: System.Xml.Serialization.XmlElementAttribute("return")]
public string echoString(string inputString) {
object[] results = this.Invoke("echoString", new object[] {inputString});
return ((string)(results[0]));
}

The ResponseNamespace="urn:LookupBorrower" makes me wonder


what NS it


is looking for 'return' to be in.
Debug shows 'results' is a one element array with that


element being


null.

I'm getting more confused by the hour.

Richard.

P.S. I'm not too concerned about XMLSpy either!

I don't understand what XMLSpy is complaining about, but


there are a


number of known errors in XMLSpy. Perhaps it's just complaining because I used the same namespace for both the WSDL and


the schema


(which is acceptable).

But there's nothing wrong with the second point. .NET will not object to the fact that <return> is unqualified, because


that's what


the schema says it should be. .NET was objecting to the fact that the child element of the SOAP Body was unqualified.

Try. You'll see.

But more importantly,

Richard,

This is not a valid doc/literal WSDL document. You need to define the WSDL differently depending on whether you want rpc/encoded, rpc/literal, of doc/literal.

Here's how you should define your WSDL if you'd like


to create a


doc/literal service conforming to the "wrapped"
programming convention (which offers the best


interoperability with


.NET).

Please provide the rest of the WSDL document.

Can we assume that you have defined the <return> element


in the WSDL?

Hi,

This combination in the WSDL used as input to wsdl2java:

       <wsdlsoap:binding style="document" ...........
       <wsdlsoap:body  use="literal" .........

Results in an empty namespace thus:

     <soapenv:Body>
        <return xmlns="">Hello World</return>
     </soapenv:Body>

Following many threads on this list it is clear


that this


is a problem.


If you are trying to consume an axis service in .net it


appears to be


a 'show stopper'. I have tried use="encoded" but .net


rejects it, and


also style="rpc" but still get xmlns="".

As yet I have not been able to identify a work


around for this.


Although there seems to some hints of a bug fix


for this


in the pipeline, it is still a problem in 1.2RC3.

Questions:
1. Is there a work around for this so


that I can


at


least use


my axis service in .net?

2. Is there a fix for this that will appear in


the next RC?
