Proxy class not reading data returned in SOAP response

[Jared]

I'm trying to create a .NET client to consume a Java web service. The
company that owns the web service does not publish a WSDL, but they do
publish an API document with examples of each supported request and
its corresponding response.

I've manually created a WSDL file based on their examples, and
generated a proxy class using WSDL.EXE. The proxy class appears to
send a valid request because I can see a valid response coming back
using a network sniffer. However, when the proxy class calls
Invoke(), it returns an object[] of the correct length, but with each
element null.

------------------------------------------------------
Here's the SOAP response I'm getting from the server (some data
changed to protect the innocent):

<?xml version="1.0" encoding="UTF-8"?>
<?Some_Company_API version="1.0"?>
<SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/1999/XMLSchema">
<SOAP-ENV:Body>
<m:TheResponse xmlns:m="Some API">
<element1 xsi:type="xsd:string">some data</element1>
<element2 xsi:type="xsd:string">some more data</element2>
</m:TheResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
------------------------------------------------------

------------------------------------------------------
Here's the method of the proxy class I'm calling:

[System.Web.Services.Protocols.SoapDocumentMethodAt tribute("http://tempuri.org/Login",
RequestNamespace="http://tempuri.org/",
ResponseNamespace="http://tempuri.org/",
Use=System.Web.Services.Description.SoapBindingUse .Literal,
ParameterStyle=System.Web.Services.Protocols.SoapP arameterStyle.Wrapped)]
[return: System.Xml.Serialization.XmlElementAttribute("elem ent1")]
public string Login(string param1, string param2, string param3, out
string element2) {
object[] results = this.Invoke("Login", new object[] {
param1,
param2,
param3});
element2 = ((string)(results[1]));
return ((string)(results[0]));
}
------------------------------------------------------

If I analyze results[] in breakmode, it has a length of 2, but each
element is null.

Is there something special I need to do to the proxy class to get it
to read the returned data?

TIA

yes, I think you need to set your RequestNamespace and ResponseNamespace to
"Some API"
not [url]http://tempuri.org[/url].

Dino,

I've updated the method attributes as shown below. I tried it with
and without setting the "ResponseElementName" param. It still fails
to populate results[], even though I'm still seeing a valid response
with my network sniffer.

----------------------------------------------------
[System.Web.Services.Protocols.SoapDocumentMethodAt tribute("http://tempuri.org/Login",
ResponseElementName="LoginResponse",
RequestNamespace="Some API",
ResponseNamespace="Some API",
Use=System.Web.Services.Description.SoapBindingUse .Literal,
ParameterStyle=System.Web.Services.Protocols.SoapP arameterStyle.Wrapped)]
[return: System.Xml.Serialization.XmlElementAttribute("elem ent1")]
public string Login(string param1, string param2, string param3, out
string element2) {
object[] results = this.Invoke("Login", new object[] {
param1,
param2,
param3});
element2 = ((string)(results[1]));
return ((string)(results[0]));
}
----------------------------------------------------


----------------------------------------------------
Is there anything wrong with my class attributes?

[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("c ode")]
[System.Web.Services.WebServiceBindingAttribute(Nam e="SomeApiSoap",
Namespace="http://tempuri.org/")]
public class SomeApi :
System.Web.Services.Protocols.SoapHttpClientProtoc ol {
...
}
----------------------------------------------------


Thanks again,

Jared

Here's my own answer based on the following post:

[url]http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&oe=UTF-8[/url]
&safe=off&threadm=avmXa.5874%24Ye.5664%40fed1read0 2&rnum=4&prev=/groups%
3Fq%3Dnull%2520%2522SOAP%253A%253ALite%2522%26num% 3D30%26hl%3Den%26lr%
3D%26ie%3DUTF-8%26oe%3DUTF-8%26safe%3Doff%26sa%3DN%26tab%3Dwg

(Note that the web service is Perl SOAP::Lite)

-----------------------------------------------------------------
[System.Web.Services.Protocols.SoapDocumentMethodAt tribute
("http://tempuri.org/Login",
ResponseElementName="LoginResponse",
RequestNamespace="Some API",
ResponseNamespace="Some API",
Use=System.Web.Services.Description.SoapBindingUse .Encoded,
ParameterStyle=System.Web.Services.Protocols.SoapP arameterStyle.Wrapped)
]
[return: System.Xml.Serialization.SoapElementAttribute("ele ment1")]
public string Login(string param1, string param2, string param3, out
string element2) {
....
}

The fixes were:

1) Use SoapBindingUse.Encoded instead of Literal
2) Use Serialization.SoapElementAttribute("element1") instead of
XmlElementAttribute("element1")
-----------------------------------------------------------------

Great, glad you were able to solve it. sorry I couldn't be more helpful.
SOAP::Lite is nice but I think its lack of WSDL support means that
development is trickier.

It works for me.
