Wow! That was a nice hack you gave me. It works perfect. Thanks a ton!!
I've been dealing with that problem for about 2.5 days now. Do you know if
this is a problem with the most recent .NET beta 2 release? I'm wondering
how anyone got a Java client to work with a .NET server before me? I
couldn't find much about my problem in the message archives.
Once again. Thanks a bunch.

The problem seems to be that some versions of .Net require that the
paramaters be explicitly specified as being in the same namespace as the
method name. Looking at the Apache code you don't seem to be able to turn
off the 'ns1' prefixing the method name or specify that the parameter names
should be prefixed with 'ns1'. Hence your parameter names are not in the
same namspace as your method name. If the method name is not explicity
qualified then the parameters, as children of the method element,
automatically belong to the method names namespace as in your first
example. The only way round this that I found was to explicitly specify the
parameter names with "ns1:" in front of them. YUCK!!
for example...
params.addElement (new Parameter("ns1:FirstNum", .... ));

Subject: response from method is zero in my Apache Java client
Ok I am still having this problem. I am passing two values to the MS
(Microsoft .NET beta 2) SOAP server to a method, "test_AddThem" which
returns, gasp, the value of the two numbers added together. If I pass the
exact XML the server requires, using an example without the Apache
libraries
which passes a static XML file, the server responds correctly. If I use
the
Apache libraries to build the XML, the server returns zero as the response.
I've found out now exactly what the difference in the XML is that is
causing
the value to be returned to be incorrect. I don't know how to make the
Apache libraries generate the 'correct' XML so that the MS server will
understand it.
The MS server does not like the "ns1" (namespace?) being added to the
test_AddThem element.
Here is the XML that works:
<?xml version='1.0' encoding='UTF-8'?>
<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance";
xmlns:xsd="http://www.w3.org/1999/XMLSchema";>
<SOAP-ENV:Body>
<test_AddThem xmlns="http://telemetrytech.net/VnocngWebService";
SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";>
<FirstNum xsi:type="xsd:int">3</FirstNum>
<SecondNum xsi:type="xsd:int">17</SecondNum>
</test_AddThem>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
Here is the XML generated by the apache libraries that results in zero
returned as the answer:
<?xml version='1.0' encoding='UTF-8'?>
<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance";
xmlns:xsd="http://www.w3.org/1999/XMLSchema";>
<SOAP-ENV:Body>
<ns1:test_AddThem xmlns:ns1="http://telemetrytech.net/VnocngWebService";
SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";>
<FirstNum xsi:type="xsd:int">3</FirstNum>
<SecondNum xsi:type="xsd:int">17</SecondNum>
</ns1:test_AddThem>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
Do you notice the difference? The 'ns1' appended to the "test_AddThem"
method. Here is the response from the first XML listing, the one that
works:
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:xsd="http://www.w3.org/2001/XM
LSchema">
<soap:Body>
<test_AddThemResponse xmlns="http://telemetrytech.net/VnocngWebService
">
<test_AddThemResult>20</test_AddThemResult>
</test_AddThemResponse>
</soap:Body>
</soap:Envelope>
This would be the response with the from the first XML listing. The
response from the Apache generated XML is exactly the same except the value
returned instead of 20 is 0.
Some reason the MS server doesn't like that "ns1" being appended to the
beginning of the "test_AddThem" element name. I don't know enough about
XML
to understand why the Apache libraries are generating this XML.
Does anyone know of a fix for this? If someone knows how to use the Apache
SOAP libraries to not add that "ns1" that would be great. If there are any
other solutions that would be great as well.
I've been trying to solve this problem for about 2.5 days now, if anyone
can
help me I will greatly appreciate it. Oh, and my Java client is listed
below if anyone would like to see it.
Thanks

Is "test_AddThemResult" the correct name of the XML element the response is
comming back in? Have you used the TCPTunnelGui to verify the XML that is
comming back? That's all I can think of.

see this article.
http://www.perfectxml.com/articles/xml/soapguide.asp
Apache SOAP doesn't like a response without xsi:type. This is a known
interop issue between Apache client and MS server. Also an Integer
serializer (and a lot others) is built in SOAPMappingRegistry for SOAP
encoding style. You don't have to set your IntSerializer.
Hope this helps.

Subject: response contains zero when should be a value in my Apache Java
c lient to a MS server
I am getting bogus data back from my IIS .NET beta 2 WebService. I am
using
the Java client below, which calls a method (test_AddThem) to add two
numbers and return the result. This result is always a '0' (zero). I have
another version of this method which adds the xsi:type attribute to each
element in the returned XML, since Microsoft's server does not normally do
this. This method works fine and returns the correct result.
I am adding to the mapping registry the deserializer to deserialize the
'test_AddThemResponse' response element as an Integer yet I still get zero
as the result.
I have been trying to find my bug for about 4 hours now with no luck.
Could
someone help me out? I will be very grateful. Thanks.
