RE: Problems calling Axis service from .NET C# client
Peter
I have seen this happen in case of dotnet .. and the reason it fails is
because dotnet expects the XML corresponding to the object that it
deserializes to have no prefixes ..
if all the prefixes are stripped off for the elements in the following
part I guess it shld work.
<ns1:loginResponse
SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:ns1="http://service.xmlinterface.xcut.clareos.com">
<loginResult href="#id0" />
</ns1:loginResponse>
<multiRef id="id0" SOAP-ENC:root="0" xsi:type="ns2:XcutResponse"
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:ns2="http://service.xmlinterface.xcut.clareos.com">
<ns2:ReturnCode xsi:type="xsd:int">0</ns2:ReturnCode>
<ns2:ReturnStatus xsi:type="xsd:boolean">true</ns2:ReturnStatus>
<ns2:ReturnString xsi:type="xsd:string">Logged

Stan,
Thanks for taking a look. I've tried proxy DLL from "wsdl.exe", adding a
web reference through .NET, and the webservice studio. While I can
generate and build the proxy in all methods named and see the SOAP
request and response, I cannot get a valid response back in .NET land
(as described in original note).

The usual way to build a C# client is:
1) Create proxy DLL from wsdl file, using this executable:
c:\Program Files\Microsoft.NET\FrameworkSDK\Bin\wsdl.exe
2) Write your client, which uses the proxy.
Did you create your client this way? If not, maybe you should give it a
try.
Another (better) way to create the proxy is via ".NET WebService Studio"
which you can download here:
http://www.gotdotnet.com/team/tools/web_svc/default.aspx
Personally, I love the studio, because it:
1) generates both proxy and client, and
2) provides a nice GUI for entering input data to test your service.
I tried your wsdl file with .NET WebService Studio, and it seems to be
okay
(I was able to create a proxy and client).
Good luck.

Hi Stan,
Attached is the entire wsdl file. Thanks!
I added a trace extension to the .NET method to follow the message
through the various stages... no luck so far.

Send me the entire wsdl file, and I can prolly help. Or send me the
URL, if you have deployed your service to the web.

Subject: Problems calling Axis service from .NET C# client
I have a web services method running on Axis (beta 1) that looks like:
XcutPlay1Response login (String id, String pw);
The return type is complex (see WSDL below). Calling from an Axis client
works fine. When invoked from .NET, I get an empty response object back
(string = null, int = 0, bool = false) and no errors. I look at the
actual SOAP messages and everything going up and down looks good (see
response message below). My service is getting invoked. Calling Axis
from .NET works with methods that do not involve complex types.
Anyone have any ideas?
Thanks.

Hello Vidyanand,
Thanks for the info. I updated my AXIS to the 4/3 build and now the
response coming back from AXIS no longer has the prefix and it works
(see details below). So, something must have changed between builds
because I am not doing anything different today? Here is the response
message that works:

I am still having problems sending a complex type as a parameter from
dotnet client to Axis web service. The WSDl for this one is attached.
When I call the AXIS service using dotnet web service studio client, I
get a java.lang.NullPointerException exception. There is nothing in the
Tomcat log. Here are the request and response messages:

The request looks good to me? The service just returns true. I would
