Description

There is a problem of interaction Axis WebService Client (as console application) with Microsoft WebService Server (as .Net application)

Here WEBService method description is from MS side:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<SetParameterValues xmlns="http://tempuri.org/">
<strUser>string</strUser>
<strBusinessSystem>string</strBusinessSystem>
<strParameter>string</strParameter>
<strValues>
<string>string</string>
<string>string</string>
</strValues>
</SetParameterValues>
</soap:Body>
</soap:Envelope>

Here real Axis SOAP envelope is from Java applicaton:

<?xml version="1.0" encoding="utf-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
<SetParameterValues xmlns="http://tempuri.org/">
<strUser>test</strUser>
<strBusinessSystem>SYS</strBusinessSystem>
<strParameter>100</strParameter>
<strValues>
<string xmlns="">123</string>
<string xmlns="">234</string>
</strValues>
</SetParameterValues>
</soapenv:Body>
</soapenv:Envelope>

As you can see in section <strValues> all of inner elements contain attribute xmlns="".
This notation does not work in MS (It is very strange, but I don't know why).
MS ignores all such lines and returns empty collection.
If I'm removing empty "xmlns" attributes all works fine.

I've already found the point where you can place fix code.

CLASS: org.apache.axis.encoding.SerializationContext
CODE:
if (!(map.getNamespaceURI().equals(Constants.NS_URI_XMLNS) && map.getPrefix().equals("xmlns")) &&
!(map.getNamespaceURI().equals(Constants.NS_URI_XML) && map.getPrefix().equals("xml")))

It need to be added one more check in the condition. Here modified condition

if (!(map.getNamespaceURI().equals(Constants.NS_URI_XMLNS) && map.getPrefix().equals("xmlns")) &&
!(map.getNamespaceURI().equals(Constants.NS_URI_XML) && map.getPrefix().equals("xml")) &&
!map.getNamespaceURI().equals(""))

Maybe I didn't take into account something, but after this change all have worked fine.
