Empty namespace causes INVALID_CHARACTER_ERR Exception
------------------------------------------------------
Key: AXIS2-2718
URL: https://issues.apache.org/jira/browse/AXIS2-2718
Project: Axis 2.0 (Axis2)
Issue Type: Bug
Components: client-api
Affects Versions: 1.2
Environment: Windows XP, IBM JDK
Reporter: Vasyl Zhabko
Server implementation is .NET, SOAP protocol 1.1. Response sent is (actual
server response):
HTTP/1.1 200 OK
Content-Type: text/xml; charset=utf-8
Content-Length:
<?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>
<Insert xmlns="https://localhost";>
<InsertResult>int</InsertResult>
<ResponseMsg>string</ResponseMsg>
<ResponseText>string</ResponseText>
</Insert>
</soap:Body>
</soap:Envelope>
Two issues here:
First: Document header (<?xml version="1.0" encoding="utf-8"?>) raises
exception:
Caused by: javax.xml.soap.SOAPException: com.ctc.wstx.exc.WstxParsingException:
Illegal processing instruction target ("xml"); xml (case insensitive) is
reserved by the specs.

Second: Remove header from response: Exception raised is:
Caused by: org.w3c.dom.DOMException: INVALID_CHARACTER_ERR: An invalid or
illegal XML character is specified.

Fix: build response like this (that I cannot do in production environment) :
HTTP/1.1 200 OK
Content-Type: text/xml; charset=utf-8
Content-Length:
<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>
<a:Insert xmlns:a="https://localhost";>
<a:InsertResult>int</a:InsertResult>
<a:ResponseMsg>string</a:ResponseMsg>
<a:ResponseText>string</a:ResponseText>
</a:Insert>
</soap:Body>
</soap:Envelope>
Everything starts working OK.
I have no control over server responses. I have responded to Axis with custom
HTTP daemon.
Similar problem exists when we are building soap request messages by providing
XML inside input stream (XSLT generated content).
