Exception:attribute must be specified for every parameter.
Hello Everybody,
I am trying to communicate with MS soap server from Apache client.
I am using ATL to create COM objects.
Server method declaration
HRESULT GetData([out,retval]BSTR *str) // which returns String and does not
take any input args
Client side my java code looks like this
Call call = new Call ();
call.setTargetObjectURI (URI);
call.setMethodName ( methodName );
call.setEncodingStyleURI( Constants.NS_URI_SOAP_ENC );
Vector params = new Vector()
call.setParams (params)
I am able to communicate with MS soap server and get the soap response.
I can see the result in the debug mode.
But when it comes to unmarshaling the returned data its throughing this
exception.
exception The 'http://www.w3.org/1999/XMLSchema-instance:type' attribute
must be specified for every parameter.
In this case there are no parameters involved in this except return value.
Is there any problem with MS soap or am I missing something in my client
code?
Thanks in advance
Prasad Vangavolu

Hi,
After I tried with modified Listener.asp its working fine (thanks to James
Snell). Only thing is MS Wizard generates Wrong ProgId value if I generate
.asp file from ATL COM Dll/Exe. After I changed it to correct ProgId its
working fine.
Thanks

Hi,
I'm not a SOAP expert, but I did have the same problem. I think it's
not possible to use Apache SOAP for a client with MS SOAP Toolkit for
the server, because MS knows the types of parameters and return values
by looking at an SDL file, while Apache has to discover the type in the
SOAP message itself. Since the MS server doesn't include this
information in the SOAP response, you get this error.
